Abstract
Anticholinergic medications have long been a mainstay of overactive bladder (OAB) treatment. Oxybutynin, a first-generation anticholinergic, still accounts for more than half of all OAB medication prescriptions, despite associations with impaired memory and cognition, as well as mounting evidence that it may increase the risk of incident dementia. This review details the current literature regarding oxybutynin and cognition, including evidence from preclinical, clinical, and real-world studies that show that oxybutynin binds nonspecifically to muscarinic receptors in the brain and is associated with adverse cognitive outcomes. We also discuss society recommendations to reduce use of oxybutynin and other anticholinergics to treat OAB.

Park JS, Choi SB, Jang WS, Kim J, Ham WS. Risks of Dementia After Treatment with an Anticholinergic, Beta-3 Agonist, or Combination of Both for an Overactive Bladder: A Korean National Cohort Study. Eur Urol Focus 2024:S2405-4569(24)00019-1. [PMID: 38388215 DOI: 10.1016/j.euf.2024.02.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2023] [Revised: 12/15/2023] [Accepted: 02/11/2024] [Indexed: 02/24/2024]
Abstract
BACKGROUND AND OBJECTIVE An overactive bladder (OAB) is primarily managed with behavioural therapy and using anticholinergics and beta-3 agonists. Reports have shown that the use of anticholinergics by OAB patients was associated with an increased risk of new-onset dementia compared with those using beta-3 agonists. This study compares the risks of dementia among patients with an OAB starting on a beta-3 agonist alone, an anticholinergic alone, or a combination treatment. METHODS Using data from the Korean National Health Insurance Service database, we studied a nationwide population cohort comprising patients newly diagnosed with an OAB who initiated their OAB medications between 2015 and 2020. The treatment types were categorised as anticholinergics (oxybutynin, solifenacin, tolterodine, trospium, fesoterodine, flavoxate, and propiverine) alone, a beta-3 agonist (mirabegron) alone, and combination therapy (an anticholinergic plus the beta-3 agonist). To evaluate the impact of cumulative drug exposure, we quantified the cumulative exposure to solifenacin and mirabegron as cumulative defined daily doses (cDDDs) using proportional hazards regression analyses, adjusted for factors known to be associated with dementia. KEY FINDINGS AND LIMITATIONS Among the study's 3 452 705 patients, 671 974 were new users of a beta-3 agonist alone (19.5%), 1 943 414 new users of anticholinergics alone (56.3%), and 837 317 receiving combination therapy (24.3%). The most common anticholinergic used both alone and as part of a combination treatment was solifenacin (42.9% and 56.3%, respectively). There was an increased risk of dementia between the users of an anticholinergic alone (adjusted hazard ratio [aHR] = 1.213; 95% confidence interval [CI], 1.195-1.232) and those taking a combination treatment (aHR = 1.345; 95% CI, 1.323-1.366) compared with the users of beta-3 agonists alone after the adjustment of covariates. However, the incidence of dementia was also significantly higher, with an increase in the cumulative dose of mirabegron (aHR = 1.062 [1.021-1.106] for 28-120 cDDDs and aHR = 1.044 [1.004-1.084)] for patients who received >121 cDDDs compared with those who received <27 cDDDs). A marked increased risk of dementia was associated with the use of solifenacin, tolterodine, fesoterodine, and propiverine, both separately and in combination with mirabegron. CONCLUSIONS AND CLINICAL IMPLICATIONS In this large Korean cohort, the use of anticholinergics with or without a beta-3 agonist increased the risk of new-onset dementia compared with the use of a beta-3 agonist alone. Given that the risk of dementia was most significantly elevated with combination treatments, care should be taken when considering combination treatment for OAB patients with risk factors for dementia. Furthermore, there could be a possible association between beta-3 agonists and dementia, although future studies are needed. PATIENT SUMMARY This study investigated the risk of dementia induced by overactive bladder (OAB) treatment in a large Korean cohort. Two representative OAB treatment drugs, anticholinergics and beta-3 agonists, both increased the risk of new-onset dementia. Clinicians should be cautious in using OAB treatment drugs since no drugs could be concluded as safe.

Abstract
INTRODUCTION Older adults are susceptible to anticholinergic effects. Dysphagia and pneumonia are associated with anticholinergic usage, though a definitive causative relationship has not been established. There is no effective way to predict the prognosis of older adults with pneumonia; therefore, this study investigates the predictive value of anticholinergic burden. METHODS Patients aged 65 years and above admitted for community-acquired pneumonia from 2011 to 2018 in Denmark were included through Danish registries. We calculated anticholinergic drug exposure using the CRIDECO Anticholinergic Load Scale (CALS). The primary outcome was in-hospital mortality, and other outcomes included intensive care unit admission, ventilator usage, length of stay, 30-day/90-day/1-year mortality, institutionalisation, home care utilisation and readmission. RESULTS 186,735 patients were included in the in-hospital outcome analyses, 165,181 in the readmission analysis, 150,791 in the institutionalisation analysis, and 95,197 and 73,461 patients in the home care analysis at follow-up. Higher CALS score was associated with higher in-hospital mortality, with a mean risk increasing from 9.9% (CALS 0) to 16.4% (CALS >10), though the risk plateaued above a CALS score of 8. A higher CALS score was also associated with greater mortality after discharge, more home health care, more institutionalizations and higher readmission rates. CONCLUSIONS High anticholinergic burden levels were associated with poor patient outcomes including short-/long-term mortality, dependence and readmission. It may be useful to calculate the CALS score on admission of older patients with pneumonia to predict their prognosis. This also highlights the importance of avoiding the use of drugs with a high anticholinergic burden in older patients.

Abstract
The evidence for the risks associated with anticholinergic agents has grown considerably in the last two decades. Not only are they associated with causing peripheral side effects such as dry mouth, blurred vision and constipation, but they can also cause central effects such as cognitive impairment; and more recently, they have consistently been linked with an increased risk of dementia and death in older people. This paper reviews the evidence for the associations of anticholinergic agents and the risk of dementia and increased mortality in dementia.

Abstract
Overactive bladder prevalence increases in older adults often complicating the management of other comorbidities. The theoretical antagonism between the parasympathetic-blocking anticholinergic agent and the parasympathetic stimulatory agents concomitantly used by patients is only recently being explored. The primary aim was to determine the frequency of the annual use of acetylcholinesterase inhibitors, overactive bladder anticholinergics, and the use of both agents in the same year. The secondary aim was measurement of the association between annual hospitalization and same-year use of both acetylcholinesterase inhibitors and anticholinergics. The US nationally representative MarketScan® Medicare databases were analyzed. In the Medicare enrollees, there were 122 020, 141 920, and 15 639 users of acetylcholinesterase inhibitors, anticholinergics, and both agents, respectively. The percentage of acetylcholinesterase inhibitor users who also used anticholinergics was 12.8%. Comparing users of both acetylcholinesterase inhibitors and anticholinergics to those using AChEI alone, 5 608 of the former experienced a hospitalization (35.9%) compared to 33 182 of the latter (31.2%). There was an increased risk of hospitalization for those using both acetylcholinesterase inhibitors and anticholinergics in the same year, with an odds ratio (OR) of 1.23 (95% CI, 1.19, 1.28). Clinicians should consider improved monitoring of the usage of both medications and clarify alternative regimens that avoid anticholinergics in at-risk older adults.

Anticholinergic burden risk and prevalence of medications carrying anticholinergic properties in elderly cancer patients in Jordan. Saudi Pharm J 2023; 31:101710. [PMID: 37559866 PMCID: PMC10406854 DOI: 10.1016/j.jsps.2023.101710] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Accepted: 07/20/2023] [Indexed: 08/11/2023] Open
Abstract
BACKGROUND Geriatric cancer patients are susceptible to adverse drug events due to the complexity of their chemotherapy regimens and collateral treatments for their comorbid conditions. Prescribing medications with anticholinergic burden characteristics can complicate their condition, leading to negative impacts on their health outcomes and quality of life, including an increase in adverse drug event frequency, physical and cognitive impairments. OBJECTIVE This study aims to examine the prevalence of anticholinergic prescribing and identify the cumulative anticholinergic load risk associated with drugs prescribed to elderly cancer patients. Also, to identify the predictors that might lead to raised anticholinergic burden in these patients. METHODOLOGY This retrospective cross-sectional study included elderly patients (age ≥ 65) diagnosed with cancer and admitted to the adult oncology unit at King Abdullah University Hospital (KAUH) in Jordan during the period between (January 1st, 2019, and January 1st, 2022). The medication charts of 420 patients were evaluated for study outcomes. RESULTS Of the total subjects, females represented 49.3%, and the average age was 72.95 (SD = 7.33). A total of 354 (84.3%) patients were prescribed at least one drug carrying anticholinergic burden properties. Median for anticholinergic medications was 3 (IQR = 4). Our study found that 194 (46.2%) patients were at a high risk of adverse events associated with anticholinergic load (cumulative score ≥ 3). Metoclopramide, furosemide, and tramadol were the most frequently prescribed drugs with anticholinergic properties. Alimentary tract drugs with anticholinergic action were the most commonly encountered items in our study population. CONCLUSION Our study revealed a significantly high prevalence of anticholinergic prescribing among elderly cancer patients. Nearly half of the patients were at high risk of developing serious effects related to anticholinergic activity from the drugs administered. Polypharmacy was strongly associated with increased anticholinergic burden score. Evidence-based recommendations utilizing prescribing strategies for safer alternatives and deprescribing of inappropriate medications could reduce such inappropriate prescribing.

Abstract
Over the past two decades, considerable data have emerged on an association between drugs with anticholinergic activity and serious adverse effects in older people. Well-recognised anticholinergic adverse effects include dry mouth, blurred vision, constipation and urinary retention. Of particular concern is the potential impact on cognitive function with several studies showing that long-term use of medicines with anticholinergic activity is associated with worsening of cognitive function, increased incidence of dementia and increased mortality. This article gives an overview of the evidence, discusses some of the tools used to identify high-risk drugs and highlights issues to consider when prescribing drugs with anticholinergic activity with a view to reducing potential risks in older people and those at highest risk of cognitive impairment.

Abstract
BACKGROUND Drugs with anticholinergic properties are associated with cognitive adverse effects, especially in patients vulnerable to central muscarinic antagonism. A variety of drugs show weak, moderate or strong anticholinergic effects. Therefore, the cumulative anticholinergic burden should be considered in patients with cognitive impairment. This study aimed to develop a Swedish Anticholinergic Burden Scale (Swe-ABS) to be used in health care and research. METHODS A systematic literature review was conducted in PubMed and Ovid Embase to identify previously published tools quantifying anticholinergic drug burden (i.e., exposure). Drugs and grading scores (0-3, no to high anticholinergic activity) were extracted from identified lists. Enteral and parenteral drugs authorized in Sweden were included. Drugs with conflicting scores in the existing lists were assessed by an expert group. Two drugs that were not previously assessed were also added to the evaluation process. RESULTS The systematic literature search identified the following nine anticholinergic burden scales: Anticholinergic Activity Scale, Anticholinergic Burden Classification, updated Anticholinergic Cognitive Burden scale, Anticholinergic Drug Scale, Anticholinergic Load Scale, Anticholinergic Risk Scale, updated Clinician-rated Anticholinergic Scale, German Anticholinergic Burden Scale and Korean Anticholinergic Burden Scale. A list of drugs with significant anticholinergic effects provided by The Swedish National Board of Health and Welfare was included in the process. The suggested Swe-ABS consists of 104 drugs scored as having weak, moderate or strong anticholinergic effects. Two hundred and fifty-six drugs were listed as having no anticholinergic effects based on evaluation in previous scales. In total, 62 drugs were assessed by the expert group. CONCLUSIONS Swe-ABS is a simplified method to quantify the anticholinergic burden and is easy to use in clinical practice. Publication of this scale might make clinicians more aware of drugs with anticholinergic properties and patients' total anticholinergic burden. Further research is needed to validate the Swe-ABS and evaluate anticholinergic exposure versus clinically significant outcomes.

Abstract
In this review, we first describe the current understanding of glial-mediated vascular function affecting the role of the blood-brain barrier (BBB) in central nervous system (CNS) disorders. BBB, mainly composed of glial and endothelial cells (ECs), is the protective structure that orchestrates the transport of substances, including ions, molecules, and cells from brain vessels into or out of the CNS. Then, we display the multiple communication between glial and vascular function based on angiogenesis, vascular wrapping, and blood perfusion in the brain. Glial can support microvascular ECs to form a blood network connecting to neurons. Astrocytes, microglia, and oligodendrocytes are the common types of glial surrounding the brain vessel. Glial-vessel interaction is required for the permeability and integrity of BBB. Glial cells surrounding the cerebral blood vessels can transmit communication signals to ECs and regulate the activity of vascular endothelial growth factor (VEGF) or Wnt-dependent endothelial angiogenesis mechanism. In addition, these glial cells monitor the blood flow in the brain via Ca2+/K+-dependent pathways. Finally, we provide a potential research direction for the glial-vessel axis in CNS disorders. Microglial activation can trigger astrocyte activation, which suggests that microglia-astrocyte interaction may play a key role in monitoring cerebral blood flow. Thus, microglia-astrocyte interaction can be the key point of follow-up studies focusing on the microglia-blood mechanism. More investigations focus on the mechanism of how oligodendrocyte progenitor cells communicate and interact with ECs. The direct role of oligodendrocytes in modulating vascular function needs to be explored in the future.

Abstract
Acanthamoeba species are capable of causing amoebic keratitis (AK). As a monotherapy, alpha-mangostin is effective for the treatment of AK; however, its bioavailability is quite poor. Moreover, the efficacy of therapy is contingent on the parasite and virulent strains. To improve readiness against AK, it is necessary to find other derivatives with accurate target identification. Beta-tubulin (BT) has been used as a target for anti-Acanthamoeba (A. keratitis). In this work, therefore, a model of the BT protein of A. keratitis was constructed by homology modeling utilizing the amino acid sequence from NCBI (GenBank: JQ417907.1). Ramachandran Plot was responsible for validating the protein PDB. The verified BT PDB was used for docking with the specified ligand. Based on an improved docking score compared to alpha-mangostin (AM), two modified compounds were identified: 1,6-dihydroxy-7-methoxy-2,8-bis(3-methylbut-2-en-1-yl)-9H-xanthen-9-one (C1) and 1,6-dihydroxy-2,8-bis(3-methylbut-2-en-1-yl)-9H-xanthen-9-one (C2). In addition, molecular dynamics simulations were conducted to analyze the interaction characteristics of the two bound BT–new compound complexes. During simulations, the TRP9, ARG50, VAL52, and GLN122 residues of BT-C1 that align to the identical residues in BT-AM generate consistent hydrogen bond interactions with 0–3 and 0–2. However, the BT-C2 complex has a different binding site, TYR 258, ILE 281, and SER 302, and can form more hydrogen bonds in the range 0–4. Therefore, this study reveals that C1 and C2 inhibit BT as an additive or synergistic effect; however, further in vitro and in vivo studies are needed.

Abstract
Bladder dysfunction, which involves inadequacies of urine storage or emptying, increases with age. Conventional medications may have insufficient efficacy for patients with refractory lower urinary tract symptoms, and their concomitant adverse events (AEs) may be intolerable for the older adult population. For decades, the botulinum toxin type A (BoNT-A) injection has been an option for managing urine frequency, urge incontinence, and voiding dysfunction in the general population refractory to conventional management. This review focuses on studies of BoNT-A application in the management of bladder dysfunction in older adult patients aged ≥ 65 years. In this target population, intravesical BoNT-A injections provide similar efficacy in idiopathic overactive bladder to that in younger adults. Good clinical response has also been demonstrated in older adult patients presenting with storage dysfunction and with various concomitant underlying neurological diseases. However, caution must be taken for the AEs that occur after intravesical BoNT-A injection, including increased post-void residual urine, acute urine retention, and urinary tract infection. Most evidence shows that age is not a major determinant of AEs after adjusting for other factors. In contrast to its application in storage dysfunction, evidence for voiding dysfunction in older adults is scarce. In general, BoNT-A may be a reasonable option for older adult patients with refractory storage dysfunction because of its promising clinical response without significant systemic AEs. Overall, clinicians should be aware of the balance between the therapeutic efficacy of BoNT-A and local AEs in vulnerable members of this population.

Abstract
OBJECTIVES Anticholinergic medications are a core treatment strategy for overactive bladder (OAB). There is evidence that exposure to anticholinergic medications is associated with an increased risk of developing dementia. We launched an initiative to inform our patients of this risk and give them an opportunity to engage in shared decision-making about their treatment. This quality improvement initiative encompassed 3 aims: (1) to evaluate the feasibility of 2 different routes to deliver the written outreach; (2) to evaluate if and how patients changed their OAB treatment; and (3) to assess satisfaction with the outreach initiative. METHODS A query was performed via the electronic medical record for all patients who had been prescribed an anticholinergic for treatment of OAB. We sent either electronic messages or traditional mail to patients. We contacted patients by telephone to assess if they received the message, were satisfied with their respective method of communication, and decided for ongoing treatment. Health care provider satisfaction was also measured. RESULTS Of the 231 patients sent the outreach, 32 were still taking the anticholinergic at the time they received the communication. The majority of patients, 84.38%, were satisfied with the initiative and elected to change therapy after learning about the increased risk of dementia. The physicians also uniformly reported satisfaction with the initiative. CONCLUSIONS Overall, this outreach initiative resulted in an increase in patient counseling that led to a change in treatment for most patients. This initiative was received favorably by patients and health care providers.

Front Neurosci 2022; 16:849291. [PMID: 35281514 PMCID: PMC8904722 DOI: 10.3389/fnins.2022.849291] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2022] [Accepted: 02/04/2022] [Indexed: 11/13/2022] Open
Abstract
Vagus nerve stimulation (VNS) delivered during motor rehabilitation enhances recovery from a wide array of neurological injuries and was recently approved by the U.S. FDA for chronic stroke. The benefits of VNS result from precisely timed engagement of neuromodulatory networks during rehabilitative training, which promotes synaptic plasticity in networks activated by rehabilitation. Previous studies demonstrate that lesions that deplete these neuromodulatory networks block VNS-mediated plasticity and accompanying enhancement of recovery. There is a great deal of interest in determining whether commonly prescribed pharmacological interventions that influence these neuromodulatory networks would similarly impair VNS effects. Here, we sought to directly test the effects of three common pharmaceuticals at clinically relevant doses that target neuromodulatory pathways on VNS-mediated plasticity in rats. To do so, rats were trained on a behavioral task in which jaw movement during chewing was paired with VNS and received daily injections of either oxybutynin, a cholinergic antagonist, prazosin, an adrenergic antagonist, duloxetine, a serotonin-norepinephrine reuptake inhibitor, or saline. After the final behavioral session, intracortical microstimulation (ICMS) was used to evaluate reorganization of motor cortex representations, with area of cortex eliciting jaw movement as the primary outcome. In animals that received control saline injections, VNS paired with training significantly increased the movement representation of the jaw compared to naïve animals, consistent with previous studies. Similarly, none of the drugs tested blocked this VNS-dependent reorganization of motor cortex. The present results provide direct evidence that these common pharmaceuticals, when used at clinically relevant doses, are unlikely to adversely impact the efficacy of VNS therapy.

Comparison with the ACB Scale in Spanish Individuals with Subjective Memory Complaints. J Pers Med 2022; 12:jpm12020207.

Abstract
The increase in life expectancy has also been accompanied by an increase in the use of medication to treat chronic diseases. Polypharmacy is associated with medication-related problems such as the increase in the anticholinergic burden. Older people are more susceptible to anticholinergic effects on the central nervous system and this, in turn, may be related to cognitive impairment. In this paper, we develop an updated anticholinergic burden scale, the CRIDECO Anticholinergic Load Scale (CALS) via a systematic review of the literature and compare it with the currently most used Anticholinergic Burden Scale (ACB). Our new scale includes 217 different drugs with anticholinergic properties, 129 more than the ACB. Given the effect that anticholinergic medications have on cognitive performance, we then used both scales to investigate the relationship between anticholinergic burden and cognitive impairment in adult Spanish subjects with subjective memory complaint. In our population, we observed an association between cognitive impairment and the anticholinergic burden when measured by the new CALS, but not when the ACB was applied. The use of a more comprehensive and upgraded scale will allow better discrimination of the risk associated with the use of anticholinergic medications on cognitive impairment. CALS can help raise awareness among clinicians of the problems associated with the use of medications, or combinations of them, with large anticholinergic effect, and promote a better personalized pharmacological approach for each patient.

Abstract
OBJECTIVES To investigate the associations between central anticholinergic burden and mortality, hospitalization, and cognitive impairment in people with dementia prescribed anticholinergic drugs for urinary symptoms. DESIGN Retrospective cohort study. SETTING AND PARTICIPANTS Patients diagnosed with dementia receiving anticholinergic medication for bladder conditions (N = 540), assembled from a large healthcare database. METHODS Central anticholinergic burden related to bladder drugs was estimated using the anticholinergic effect on cognition scale. Data were linked to national mortality and hospitalization data sources, and serially recorded Mini-Mental State Examination scores were used to investigate cognitive decline. RESULTS Patients had a median survival of 4.1 years. Urinary drugs with a high anticholinergic effect on cognition score (tolterodine, oxybutynin) were associated with a 55% increased mortality risk (hazard ratio 1.55; 95% confidence interval 1.19‒2.01; P = .001) compared with drugs with low or no central anticholinergic burden (darifenacin, fesoterodine, trospium, mirabegron, solifenacin). Cognitive decline over a 24-month period around diagnosis was only detectable in the high central anticholinergic group, but there was no significant difference in cognitive trajectories between the high and low/no anticholinergic bladder drug groups. No increase of emergency hospitalization risk was seen in relation to central anticholinergic burden. CONCLUSIONS AND IMPLICATIONS Urinary drugs with high central anticholinergic burden cause more harm than those acting peripherally and should be avoided in people with dementia. Further research is needed to test whether centrally acting anticholinergic agents in general cause worse outcomes in dementia.

Abstract
Overactive bladder is a symptom complex consisting of bothersome storage urinary symptoms that is highly prevalent among both sexes and has a significant impact on quality of life. Various antimuscarinic agents and the beta-3 agonists mirabegron and vibegron are currently available for the treatment of OAB. Each drug has specific pharmacologic properties, dosing schedule and tolerability profile, making it essential to individualize the medical treatment for the patient's characteristics and expectations. In this manuscript, we review the most important factors involved in the contemporary pharmacological treatment of OAB.

Abstract
Overactive bladder (OAB) is often treated with medications that block the cholinergic receptors in the bladder (known as anticholinergics). The effect of this medication class on cognition and risk of dementia has been increasingly studied over the past 40 years after initial studies suggested that the anticholinergic medication class could affect memory. Short-term randomized clinical trials demonstrated that the administration of the anticholinergic oxybutynin leads to impaired memory and attention, and large, population-based studies showed associations between several different anticholinergic medications and dementia. However, trials involving anticholinergics other than oxybutynin have not shown such substantial effects on short-term cognitive function. This discordance in results between short-term cognitive safety of OAB anticholinergics and the long-term increased dementia risk could be explained by the high proportion of patients using oxybutynin in the OAB subgroups of the dementia studies, or a study duration that was too short in the prospective clinical trials on cognition with other OAB anticholinergics. Notably, all studies must be interpreted in the context of potential confounding factors, such as when prodromal urinary symptoms associated with the early stages of dementia lead to an increase in OAB medication use, rather than the use of OAB medication causing dementia. In patients with potential risk factors for cognitive impairment, the cautious use of selected OAB anticholinergic agents with favourable physicochemical and pharmacokinetic properties and clinical trial evidence of cognitive safety might be appropriate.

Abstract
Idiopathic overactive bladder (OAB) is a chronic condition that negatively affects quality of life, and oral medications are an important component of the OAB treatment algorithm. Recent literature has shown that anticholinergics, the most commonly prescribed oral medication for the treatment of OAB, are associated with cognitive side effects including dementia. β3-adrenoceptor agonists, the only alternative oral treatment for OAB, are similar in efficacy to anticholinergics with a more favorable side effect profile without the same cognitive effects. However, there are marked cost variations and barriers to access for OAB medications, resulting in expensive copays and medication trial requirements that ultimately limit access to β3-adrenoceptor agonists and more advanced procedural therapies. This contributes to and perpetuates health care inequality by burdening the patients with the least resources with a greater risk of dementia. When prescribing these medications, health care professionals are caught in a delicate balancing act between cost and patient safety. Through multilevel collaboration, we can help disrupt health care inequalities and provide better care for patients with OAB.

Abstract
OBJECTIVE Anticholinergic drugs are the mainstay treatment of OAB. Anticholinergic load is the cumulative effect of taking anticholinergic medication. Recent evidence suggests that in the elderly this can have a detrimental affect, with the potential to develop dementia. A previous study found that knowledge of anticholinergic load was lacking in our healthcare professionals. The aim of this study was to assess knowledge of pharmacists, who in the UK have the potential where qualified to prescribe as well as dispense. STUDY DESIGN A questionnaire was formulated based on the previous study. It was sent out to 418 pharmacists from; a south London hospital trust, a south London clinical commissioning group and United Kingdom Clinical Pharmacists Association. RESULTS Seventy-five pharmacists completed the questionnaire. Solifenacin and tolterodine was the most popular drug prescribed in the elderly without dementia, whilst mirabegron was the most popular in the elderly with dementia. One pharmacist suggested using oxybutynin. Sixty-two percent discuss anticholinergic load with the patients, 40 % advice prescribers and 42 % consider anticholinergic load when dispensing the drug. Fifteen percent have had patients report confusion/memory loss. Thirty percent know how to assess anticholinergic load. Only 15 % felt dementia was a concern with anticholinergic drugs. Worryingly, 54 % though mirabegron exerted anticholinergic effects. CONCLUSION This is the first study looking at pharmacist knowledge on the use of anticholinergic medication for OAB in elderly women. Knowledge amongst all healthcare professionals including pharmacists is lacking and needs to be improved.

Abstract
Background: The muscarinic receptor antagonist trospium chloride (TCl) is used for pharmacotherapy of the overactive bladder syndrome. TCl is a hydrophilic positively charged drug. Therefore, it has low permeability through biomembranes and requires drug transporters for distribution and excretion. In humans, the organic cation transporters OCT1 and OCT2 and the multidrug and toxin extrusion MATE1 and MATE2-K carriers showed TCl transport. However, their individual role for distribution and excretion of TCl is unclear. Knockout mouse models lacking mOct1/mOct2 or mMate1 might help to clarify their role for the overall pharmacokinetics of TCl. Method: In preparation of such experiments, TCl transport was analyzed in HEK293 cells stably transfected with the mouse carriers mOct1, mOct2, mMate1, and mMate2, respectively. Results: Mouse mOct1, mOct2, and mMate1 showed significant TCl transport with Km values of 58.7, 78.5, and 29.3 µM, respectively. In contrast, mMate2 did not transport TCl but showed MPP+ transport with Km of 60.0 µM that was inhibited by the drugs topotecan, acyclovir, and levofloxacin. Conclusion: TCl transport behavior as well as expression pattern were quite similar for the mouse carriers mOct1, mOct2, and mMate1 compared to their human counterparts.

Abstract
PURPOSE OF REVIEW This article provides an overview of the clinical presentation, investigations, and treatment options for lower urinary tract and bowel dysfunction in patients with neurologic diseases. RECENT FINDINGS The site of the neurologic lesion influences the pattern of lower urinary tract dysfunction. Antimuscarinic agents are first-line management for urinary incontinence; however, the side effect profile should be considered when prescribing them. β3-Receptor agonists are a promising alternative oral medication. Botulinum toxin injections into the detrusor have revolutionized the management of neurogenic detrusor overactivity.Bowel dysfunction commonly presents as constipation and fecal incontinence. Gastrointestinal emergencies may arise, including intestinal pseudoobstruction, intussusception, volvulus, and stercoral ulcer (ulcer of the colon due to pressure and irritation resulting from severe, prolonged constipation). Bowel function tests in neurologic patients often show a combination of slow transit and anorectal dysfunction. Management for slow transit constipation includes bulking agents, softening agents, yogurt/probiotics, and prokinetic agents. Suppositories, botulinum toxin injections, and transanal irrigation are options for managing anorectal constipation. SUMMARY Functions of the lower urinary tract and bowel are commonly affected in neurologic disease. Neurologists play an important role in assessing lower urinary tract and bowel symptoms in their patients and planning treatment strategies, often in collaboration with specialist teams.

Abstract
PURPOSE Bladder antimuscarinic (BAM) drug use is associated with increased risk of Alzheimer's disease and related dementias (ADRD). It is hypothesized that BAMs with non-selective receptor binding may increase ADRD risk more than M3-selective BAMs. This study compared ADRD risk for users of non-selective and M3-selective BAMs and examines ADRD risk associated with overall BAM use. METHODS Retrospective cohort study of Medicare claims for 71 688 individuals who used BAM drugs during 2007-2009 without an ADRD diagnosis. We compared ADRD incidence (2011-2016) between non-selective BAM users (fesoterodine, flavoxate, oxybutynin, tolterodine, trospium) and M3-selective BAM users (darifenacin, solifenacin). Logistic regressions compared individuals using target drugs in the same category of total standardized daily doses (TSDD) as a standardized measure of drug exposure, and adjusted for age, sex, race/ethnicity, healthcare utilization, other medication use, socioeconomic status, and comorbidities. Secondary analyses compared ADRD risk associated with different doses of BAMs overall. RESULTS Non-selective BAM use (compared to M3-selective) was not significantly associated with ADRD incidence. Odds ratios for non-selective use were 0.97 (CI: 0.89-1.04) for 1-364 TSDD, 0.94 (CI: 0.83-1.06) for 365-729, 1.00 (CI: 0.87-1.16) for 730-1094, and 1.03 (CI: 0.88-1.20) for >1094. Higher TSDD of BAMs overall (combining both non-selective and M3-selective BAMs), when compared to 1-364 TSDD, were associated with increased ADRD incidence (OR = 1.05 (CI: 0.99-1.10) for 365-729, OR = 1.11 (CI: 1.05-1.17) for 730-1094, and OR = 1.10 (CI: 1.04-1.15) for >1094). CONCLUSIONS Non-selective and M3-selective BAM users had similar odds of ADRD incidence, and BAM use overall was significantly associated with ADRD incidence.

Abstract
AbstractLower urinary tract dysfunction is a common sequel of neurological disease resulting in symptoms that significantly impacts quality of life. The site of the neurological lesion and its nature influence the pattern of dysfunction. The risk for developing upper urinary tract damage and renal failure is considerably lower in patients with slowly progressive nontraumatic neurological disorders, compared with those with spinal cord injury or spina bifida. This acknowledged difference in morbidity is considered when developing appropriate management algorithms. The preliminary evaluation consists of history taking, and a bladder diary and may be supplemented by tests such as uroflowmetry, post-void residual measurement, renal ultrasound, (video-)urodynamics, neurophysiology, and urethrocystoscopy, depending on the clinical indications. Incomplete bladder emptying is most often managed by intermittent catheterization, and storage dysfunction is managed by antimuscarinic medications. Intra-detrusor injections of onabotulinumtoxinA have revolutionized the management of neurogenic detrusor overactivity. Neuromodulation offers promise for managing both storage and voiding dysfunction. In select patients, reconstructive urological surgery may become necessary. An individualized, patient-tailored approach is required for the management of lower urinary tract dysfunction in this special population.

Abstract
INTRODUCTION Overactive bladder is a common problem women suffer from, with its incidence increasing with age. The mainstay of treatment is antimuscarinic medication. There is growing evidence that antimuscarinics may increase the risk of cognitive impairment, dementia, and even death. AREAS COVERED This review explores the evidence that antimuscarinics increase the risk of cognitive impairment, dementia, and death. It evaluates how best to treat overactive bladder the older woman. EXPERT OPINION The evidence suggests that antimuscarinics increase the risk of cognitive impairment and dementia in the older adult. Care should be taken to use an antimuscarinic that is less likely to cross the blood-brain barrier and thus reduce the risk of these significant adverse events. A patient's anticholinergic load also needs to be considered when treating this group. Other treatment options such as fluid management, bladder retraining, vaginal estrogens, mirabegron, Onabotulinum toxin A and neuromodulation can be used instead.

Abstract
Overactive bladder syndrome (OAB) is defined as urinary urgency, usually accompanied by frequency and nocturia, with or without urgency incontinence, in the absence of urinary tract infection or other obvious pathology. The mainstay of treatment of OAB is anticholinergic/antimuscarinic medication. These drugs block muscarinic receptors throughout the body, not only the bladder, including in the brain, which may lead to cognitive side effects. Anticholinergic load or burden is the cumulative effect of taking drugs that are capable of producing anticholinergic adverse effects. The elderly are more susceptible to these effects, especially as there is increased permeability of the blood brain barrier. The anticholinergic drugs for OAB are able to enter the central nervous system and lead to central side effects. There is increasing evidence that a high anticholinergic load is linked to the development of cognitive impairment and even dementia. Some studies have found an increased risk of mortality. In view of this, care is needed when treating OAB in the elderly. Trospium chloride is a quaternary amine anticholinergic, which has a molecular structure, which theoretically means it is less likely to cross the blood brain barrier and exert central side effects. Alternatively, mirabegron can be used, which is a beta-3 adrenoceptor agonist, which does not add to the anticholinergic load or exert central nervous system side effects. Conservative therapy can be used as an alternative to pharmacological treatment in the form of behavioral modification, fluid management and bladder retraining. Neuromodulation or the use of botox can also be alternatives, but success may be less in the older adult and will require increased hospital attendances.

Abstract
Anticholinergic drugs can be used as a treatment for many diseases. However, anticholinergic drugs are also known for their cognition-related side effects. Recently, there has been an increasing number of reports indicating a positive association between exposure to anticholinergic drugs and Alzheimer's disease (AD). Our novel study provides evidence of interactions between two representative anticholinergic drugs [Chlorpheniramine (CPM), a common antihistamine, and Trazodone (TRD), an antidepressant] with neuroprotective amyloid-beta (Aβ) chaperone, lipocalin-type prostaglandin D synthase (L-PGDS) and the amyloid beta-peptide (1–40). Here, we demonstrate that CPM and TRD bind to L-PGDS with high affinity where chlorpheniramine exhibited higher inhibitory effects on L-PGDS as compared to Trazodone. We also show that the interactions between the drug molecules and Aβ(1–40) peptides result in a higher fibrillar content of Aβ(1–40) fibrils with altered fibril morphology. These altered fibrils possess higher cytotoxicity compared to Aβ(1–40) fibrils formed in the absence of the drugs. Overall, our data suggest a mechanistic link between exposure to anticholinergic drugs and increased risk of Alzheimer's disease via inhibition of the neuroprotective chaperone L-PGDS and direct modification of Aβ amyloid morphology and cytotoxicity.

Abstract
Muscarinic M3 receptor antagonists and inverse agonists displaying high affinity and subtype selectivity over the antitarget M2 are valuable pharmacological tools and may enable improved treatment of chronic obstructive pulmonary disease (COPD), asthma, or urinary incontinence. On the basis of known M3 antagonists comprising a piperidine or quinuclidine unit attached to a biphenyl carbamate, 5-fluoro substitution was responsible for M3 subtype selectivity over M2, while 3'-chloro substitution substantially increased affinity through a σ-hole interaction. Resultantly, two piperidinyl- and two quinuclidinium-substituted biphenyl carbamates OFH243 (13n), OFH244 (13m), OFH3911 (14n), and OFH3912 (14m) were discovered, which display two-digit picomolar affinities with Ki values from 0.069 to 0.084 nM, as well as high selectivity over the M2 subtype (46- to 68-fold). While weak inverse agonistic properties were determined for the biphenyl carbamates 13m and 13n, neutral antagonism was observed for 14m and 14n and tiotropium under identical assay conditions.

Abstract
In vitro and in vivo binding sites of [3H]-labeled 5-hydroxymethyltolterodine (5-HMT), a new radioligand for labeling muscarinic receptors in rat tissues were characterized. Specific [3H]5-HMT binding in rat tissues was saturable and of high affinity in each tissue. The dissociation constant (Kd) was significantly lower in bladder and heart than in submaxillary gland. Significant levels of in vivo specific [3H]5-HMT binding by intravenous injection of the radioligand were detected in tissues, except for cerebral cortex. Thus, [3H]5-HMT was shown to specifically label muscarinic receptors in rat tissues, suggesting a useful radioligand for labeling muscarinic receptors with high affinity.

Abstract
Background Studies have shown an association between lower urinary tract symptoms (LUTS) and an increased risk of dementia. Whether anticholinergic use contributes to the development of dementia in patients with LUTS remains unknown, especially in Asian populations. This study aims to investigate the association between anticholinergic use and dementia in patients with LUTS. Methods This study included patients aged 50 years and over with newly diagnosed LUTS (January 2001 to December 2005), divided into four groups according to their cumulative defined daily doses (cDDDs) of anticholinergics: < 28 cDDDs, 28–84 cDDDs, 85–336 cDDDs, ≥337 cDDDs. Patients were followed up until dementia developed or until the end of 2012. Results We recruited a total of 16,412 patients. The incidence of dementia was 10% in the < 28 cDDD group, 8.9% in the 28–84 cDDD group, 11.5% in the 85–336 cDDD group, and 14.4% in the ≥337 cDDD group (p = .005). In a Cox proportional hazards analysis, the adjusted hazard ratio of dementia was 1.15 (95% CI = 0.97–1.37) in the 85–336 cDDD group, and 1.40 (95% CI = 1.12–1.75) in the ≥337 cDDD group after adjusting for covariates. Conclusions Our study indicates that higher cumulative anticholinergic exposure is associated with an increase in the risk of incident dementia in patients with LUTS aged 50 years of age and over. Either using one anticholinergic agent or switching anticholinergic agents cumulatively increases this risk. Therapeutic risks and benefits of using anticholinergics in LUTS treatment should be clinically reviewed and weighed.

Abstract
INTRODUCTION AND HYPOTHESIS To assess cognitive changes in women 12 months after starting anticholinergic medications for overactive bladder syndrome (OAB). METHODS We present a prospective cohort study assessing changes in cognition in women seen in a referral urogynecology practice. We compared women who started anticholinergic OAB medications with women not on anticholinergic OAB medications. The primary outcome was change over time on the Montreal Cognitive Assessment (MOCA) screening score. At enrollment, women completed a baseline MOCA screening, a Geriatric Depression Screen (GDS), and an assessment of medications to create an anticholinergic burden score (ACB). At 3, 6, 9, and 12 months after enrollment women were administered the MOCA, GDS, and a review of their medications and medical problems. Statistical analysis was performed using a linear mixed effects model taking into account correlated error terms given multiple MOCA assessments at various time points per patient. RESULTS A total of 106 women were enrolled, 60 in the OAB medication group and 46 in the control (non-OAB medication) group. The mean age was 77 years, 93% of women were Caucasian, and 98% completed high school, with no difference between groups. Over time there was no difference in change of MOCA score between the OAB and control groups when controlling for age, GDS score, and ACB score (p = 0.78). This association did not change when women with a neurological diagnosis were excluded (n = 6). On average MOCA scores for the OAB group increased by 0.76 over 12 months and the control group increased 0.39, with no difference between the groups (p = 0.53). CONCLUSIONS We found no changes in MOCA scores between OAB medication and control groups after controlling for age, depression, and polypharmacy after 12 months of follow-up.

Abstract
This study aimed to investigate the cognitive burden and polypharmacy in elderly patients treated with anticholinergics for an overactive bladder. We conducted a retrospective study of patients with an overactive bladder receiving treatment at two hospitals in Japan (Nara Medical University Hospital and Saiseikai Nara Hospital). Prescription data were collected from the medical records of the patients registered between January 2013 and April 2014. The Anticholinergic Cognitive Burden Scale was used to estimate the severity of the anticholinergic effects on the cognition of each patient. We collected the prescription data of 584 and 246 patients from the Nara Medical University Hospital and Saiseikai Nara Hospital, respectively. The mean daily total Anticholinergic Cognitive Burden score ranged between 3 and 4 (3.59 ± 1.16 at Nara Medical University Hospital vs 3.32 ± 0.78 at Saiseikai Nara Hospital, P < 0.01). At both hospitals, the mean number of prescriptions was >5 in patients ≥75 years (5.95 ± 4.43 and 5.64 ± 3.90 at Nara Medical University Hospital and Saiseikai Nara Hospitals, respectively). Our findings suggest that 10%-20% of elderly patients (≥65 years) receiving treatment with anticholinergics for an overactive bladder are in a state of polypharmacy. The total anticholinergic cognitive burden of each patient mainly depends on the anticholinergics being used for treating the overactive bladder. Especially for elderly patients with a high risk of adverse effects, including cognitive impairment, careful attention needs to be paid during selection of drugs for treating patients with an overactive bladder.

Abstract
BACKGROUND Preclinical and some human data suggest allosteric modulation of the muscarinic M1 receptor (CHRM1) is a promising approach for the treatment of schizophrenia. However, it is suggested there is a subgroup of participants with schizophrenia who have profound loss of cortical CHRM1 (MRDS). This raises the possibility that some participants with schizophrenia may not respond optimally to CHRM1 allosteric modulation. Here we describe a novel methodology to measure positive allosteric modulation of CHRM1 in human CNS and the measurement of that response in the cortex, hippocampus, and striatum from participants with MRDS, non-MRDS and controls. METHODS The cortex (Brodmann's area 6), hippocampus, and striatum from 40 participants with schizophrenia (20 MRDS and 20 non-MRDS) and 20 controls were used to measure benzyl quinolone carboxylic acid-mediated shift in acetylcholine displacement of [3H]N-methylscopolamine using a novel in situ radioligand binding with autoradiography methodology. RESULTS Compared with controls, participants with schizophrenia had lower levels of specific [3H]N-methylscopolamine binding in all CNS regions, whilst benzyl quinolone carboxylic acid-modulated binding was less in the striatum, Brodmann's area 6, dentate gyrus, and subiculum. When divided by subgroup, only in MRDS was there lower specific [3H]N-methylscopolamine binding and less benzyl quinolone carboxylic acid-modulated binding in all cortical and subcortical regions studied. CONCLUSIONS In a subgroup of participants with schizophrenia, there is a widespread decreased responsiveness to a positive allosteric modulator at the CHRM1. This finding may have ramifications it positive allosteric modulators of the CHRM1 are used in clinical trials to treat schizophrenia as some participants may not have an optimal response.

Abstract
The present study aimed to characterize muscarinic receptor binding of fesoterodine, 5-hydroxymethyl tolterodine (5-HMT), and tolterodine in bladder and other tissues of rats after their oral, intravenous, or intravesical administration. Muscarinic receptors in tissues were measured by using [N-methyl-3H]scopolamine methyl chloride ([3H]NMS). The in vitro binding affinity for muscarinic receptors was the highest by 5-HMT, followed by tolterodine and fesoterodine. Fesoterodine exhibited lower affinity in rat submaxillary gland than in detrusor muscle and urothelium. Muscarinic binding affinities of 5-HMT and tolterodine were similar among tissues. The duration of binding of oral fesoterodine to muscarinic receptors was longer in bladder than in submaxillary gland, heart, and lung, and its binding was little observed in colon and cerebral cortex. Binding activity of intravenous 5-HMT to muscarinic receptors was significantly observed in all tissues, except cerebral cortex, with a longer duration in bladder. Significant binding of bladder detrusor and urothelial muscarinic receptors was observed following intravesical instillation of 5-HMT. This selectivity may be attributed to the direct blockade of bladder receptors by excreted urinary 5-HMT. Thus, fesoterodine may be efficacious as a treatment for patients with overactive bladder.

Antimuscarinic agents are now widely used as the pharmacological therapy for overactive bladder (OAB) because neuronal (parasympathetic nerve) and non-neuronal acetylcholine play a significant role for the bladder function. In this review, we will highlight basic and clinical aspects of eight antimuscarinic agents (oxybutynin, propiverine, tolterodine, solifenacin, darifenacin, trospium, imidafenacin, and fesoterodine) clinically used to treat urinary dysfunction in patients with OAB. The basic pharmacological characteristics of these eight antimuscarinic agents include muscarinic receptor subtype selectivity, functional bladder selectivity, and muscarinic receptor binding in the bladder and other tissues. The measurement of drug-receptor binding after oral administration of these agents allows for clearer understanding of bladder selectivity by the integration of pharmacodynamics and pharmacokinetics under in vivo conditions. Their central nervous system (CNS) penetration potentials are also discussed in terms of the feasibility of impairments in memory and cognitive function in elderly patients with OAB. The clinical aspects of efficacy focus on improvements in the daytime urinary frequency, nocturia, bladder capacity, the frequency of urgency, severity of urgency, number of incontinence episodes, OAB symptom score, and quality of life (QOL) score by antimuscarinic agents in patients with OAB. The safety of and adverse events caused by treatments with antimuscarinic agents such as dry mouth, constipation, blurred vision, erythema, fatigue, increased sweating, urinary retention, and CNS adverse events are discussed. A dose-dependent relationship was observed with adverse events, because the risk ratio generally increased with elevations in the drug dose of antimuscarinic agents. Side effect profiles may be additive to or contraindicated by other medications.

Abstract
Overactive bladder syndrome (OAB) has a high prevalence within the population and has a negative effect on quality of life. Although the precise pathophysiology has yet to be fully elucidated, pharmacotherapeutic agents have been developed targeting two main pathways, antimuscarinic drugs and β3-adrenoreceptor agonists. Conservative management strategies, for example, bladder training, should be used as first-line treatment, with pharmacotherapy used as an adjunct if this is insufficiently effective. Antimuscarinics have a moderate effect on treating the symptoms of OAB, are associated with side effects, particularly dry mouth, and have low adherence rates in the long term. No single agent has consistently shown superiority over another. Antimuscarinics can affect cognition and may contribute to the anticholinergic burden in elderly patients. Mirabegron, a β3-agonist, appears to be as effective as antimuscarinics in improving symptoms of OAB with fewer side effects and improved adherence, and is currently recommended if treatment with antimuscarinics has failed. A combination of an antimuscarinic and β3-agonist may be worth considering if symptoms remain refractory or to reduce the side-effect profile associated with higher doses of antimuscarinics.Level of evidence: Not applicable.

Abstract
Overactive bladder (OAB) syndrome is a common, complex, and challenging condition. To assist the management of these patients, the European Association of Urology (EAU) updates its guidelines annually. This review reports the presentations from the symposium titled “Dealing with complex OAB patient profiles: in or out of the EAU guidelines?” held at the 32nd EAU Annual Congress in March 2017 in London. The symposium focused on three groups of OAB patients: women who may also suffer pelvic organ prolapse, stress urinary incontinence, the genitourinary syndrome of menopause (GSM); patients at risk of cognitive impairment; and elderly patients. The aim of the symposium was to determine how the 2017 EAU guidelines can best assist physicians, as well as to assess the benefits of fesoterodine in these patients. The EAU guidelines recommend antimuscarinic agents (grade A) for the medical treatment of OAB. In women, OAB is correlated with GSM, both of which are underdiagnosed and undertreated. Fesoterodine decreases OAB symptoms and the associated limitation of physical activity. A combination of fesoterodine and vaginal estrogens is appropriate for OAB associated with GSM. In patients at risk of cognitive impairment, prescribers should pay particular attention to the choice of medication. Fesoterodine is a Pgp substrate with limited ability to cross the blood–brain barrier, which may explain the lack of negative effects on the central nervous system observed in clinical trials of this agent. OAB should not be regarded as a normal consequence of aging. Fesoterodine has been extensively investigated in the elderly, and is the only anticholinergic drug licensed for OAB in this population, rated B (beneficial) according to the Fit for the Aged classification for lower-urinary-tract symptoms. The EAU guidelines are a valuable resource for physicians managing patients with OAB, and the pharmacological properties of fesoterodine offer credible clinical advantages in these three patient groups.

Abstract
OBJECTIVE This technical update addendum reviews success rates and comparative evidence of the anticholinergic fesoterodine, as well as mechanism of action, safety profile, success rates, and comparative evidence of the β3 agonist mirabegron in the treatment of non-neurogenic overactive bladder syndrome (OAB). This adds to OAB pharmacotherapy recommendations initially published in 2012. INTENDED USERS Residents and other trainees, primary care practitioners, gynaecologists, urologists, urogynaecologists, and other health care providers who assess, counsel, and treat women with OAB. TARGET POPULATION Adult women with symptomatic OAB. OPTIONS This addition relates to fesoterodine, mirabegron, and anticholinergic-β3 agonist combination pharmacotherapy. OUTCOMES The outcomes of interest are clinical efficacy of fesoterodine compared with no treatment or other OAB therapies; mechanism of action and safety profile of mirabegron, clinical efficacy of mirabegron compared to no treatment or other OAB therapies; clinical efficacy of anticholinergic-β3 agonist combination pharmacotherapy for OAB. EVIDENCE PubMed, Medline, and the Cochrane Database were searched using the key words "fesoterodine" and "mirabegron." Results were restricted to English or French and human clinical and pharmacological research. Animal research and clinical studies including only male participants were excluded. Articles were included until the end of December 2016. Grey literature was not searched. Clinical practice guidelines, guidelines of specialty societies, and systematic reviews were included. RCTs and observational studies were included when evidence for the outcome of interest or in the target population was not available from systematic reviews. New studies not yet included in systematic reviews were also included. References of included articles were also searched to ensure comprehensive inclusion of relevant literature. VALUES The content and recommendations were drafted and agreed upon by the principal author, as well as members of the Urogynaecology Committee. The Board of the SOGC approved the final draft for publication. The quality of evidence was rated using the criteria described in the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology framework. The Summary of Findings is available upon request. BENEFITS, HARMS, AND/OR COSTS It is expected that this technical update will benefit patients with OAB by providing physicians and other interested health care providers with additional options for and knowledge of safe and effective OAB pharmacotherapy. The benefits clearly outweigh the potential harms or costs of implementation of this technical update, although there are no direct harms or costs identified. UPDATES: "Evidence will be reviewed 5 years after publication to decide whether all or part of the document should be updated. However, if important new evidence is published prior to the 5-year cycle, the review process may be accelerated for a more rapid update of some recommendations." SPONSORS Not applicable.

Abstract
INTRODUCTION The mainstay of overactive bladder treatment is the use of anticholinergic medication with its common side effects well known. This review focused on three less well-known safety issues when treating OAB. Areas covered: Patients with increased anticholinergic load are at risk of cognitive decline, dementia or even death. The elderly are particularly at risk due to polypharmacy. Botulinum toxin carries the risk of high urinary residuals, urinary tract infection and need to self catheterise. The use of vaginal oestrogens may improve OAB symptoms, but there is concern in those with a history of breast cancer. Studies have shown that the systemic absorption is negligible and does not increase the risk of recurrence. Expert Opinion: Improvement in assessing anticholinergic load is needed with the development of a universal drug scale. To avoid increasing load, Mirabegron or botulinum toxin can be used instead. There is no consensus of the use of prophylactic antibiotics when injecting botulinum toxin and at what residual to initiate self catheterisation. Despite evidence showing that the use of vaginal oestrogens is safe in those with a history of cancer, it is not fully supported by any health body. Further work is needed in those using aromatase inhibitors.

Abstract
OBJECTIVE Use of anticholinergic drugs in older people is associated with increased risk of cognitive decline and of dementia and death. METHOD We identified drugs widely used in older people and attempted to classify their anticholinergic effect on cognition (AEC) according to our three-point scale which scored AEC according to in vitro anticholinergic potency, capacity to cross the blood-brain barrier and statements made in standard texts. RESULTS In total, 165 drugs were examined. We identified 21 drugs with an AEC score of 3, 18 with a score of 2, 21 with a score of 1 and 62 with a score of 0. Owing to insufficient information, we were unable to classify 43 drugs. CONCLUSIONS A large number of drugs commonly used in older people are likely to be associated with cognitive impairment.

Abstract
PURPOSE OF REVIEW Lower urinary tract and sexual dysfunction are commonly reported sequelae of neurologic disease and have a significant impact on quality of life. This article presents an up-to-date summary of the clinical presentation, investigations, and treatment options for urogenital dysfunction in patients with neurologic disease. RECENT FINDINGS The pattern of lower urinary tract dysfunction is influenced by the site of the neurologic lesion. The risk for developing upper urinary tract damage is considerably less in patients with slowly progressive nontraumatic neurologic disorders, as compared to those with spinal cord injury or spina bifida. Investigations such as urinalysis, ultrasonography, and urodynamics provide further information about the cause and nature of lower urinary tract dysfunction. Antimuscarinic agents are the first-line management of urinary incontinence; however, side effect profile and anticholinergic burden should be considered when prescribing medications. β3-Adrenergic receptor agonists are a promising alternative oral medication. Tibial and sacral neuromodulation have been shown to be effective for managing incontinence, as well as urinary retention due to Fowler syndrome. Intradetrusor injections of onabotulinumtoxinA have revolutionized the management of neurogenic detrusor overactivity. SUMMARY Neurologic patients reporting urogenital symptoms require a comprehensive evaluation for planning a patient-tailored approach to management. Neurologists are increasingly inquiring about lower urinary tract and sexual functions and becoming involved in the management of these disorders.

Abstract
PURPOSE Previous studies suggest an association between use of anticholinergic drugs in elderly patients and cognitive impairment. However, there are still limited data on the association of anticholinergic drug use and cognitive impairment as well as contribution of individual drugs to anticholinergic load using large, well-documented patient cohorts treated in geriatric units from Europe. METHODS We investigated 797,440 prescriptions to 89,579 hospitalized patients treated in geriatric units within the GiB-DAT database. Data of all patients discharged between 1 January 2013 and 30 June 2015 was included. The Anticholinergic Cognitive Burden (ACB) scale was used to classify anticholinergic drugs as definite (score 2 or 3) and possible anticholinergics (score 1). Cognitive function was determined using Mini-Mental State Examination (MMSE) and the standardized scale for dementia (4D+S). RESULTS In two multivariable logistic regression models age, sex, number of drugs and ACB total scores were identified as variables independently associated with cognitive impairment as measured by MMSE (odds ratio per ACB unit 1.114, 95% CI 1.099-1.130) or the diagnosis dementia (odds ratio 1.159 per ACB unit, 95% CI 1.144-1.173, both p < 0.0001). High anticholinergic load was associated with patients with severe cognitive impairment (p < 0.05 for all pairwise comparisons). ACB score 3 anticholinergic drugs contributed 77.9% to the cumulative amount of ACB points in patients with an anticholinergic load of 3 and higher. CONCLUSIONS Using a cross-sectional study design, a significant positive association between anticholinergic drug load and cognitive impairment in European patients treated in specialised geriatric units was found. The most frequently used definitve anticholinergic drugs were quetiapine, amitriptyline and carbamazepine.

Abstract
INTRODUCTION AND HYPOTHESIS Anticholinergic medication is the medical treatment for overactive bladder (OAB). These drugs can act on the central nervous system and can lead to cognitive decline, dementia, and potentially death. Patients taking drugs with anticholinergic effects increase their anticholinergic burden-defined as the cumulative effect of taking one or more drugs that can have adverse effects. When prescribing anticholinergic medication for the elderly, we must choose the right drug. We aimed to discover the level of understanding on this subject and its application to real clinical practice amongst our healthcare professionals (HCPs). METHODS An 18-point questionnaire was distributed to urogynaecologists, general gynaecologists, urologists, geriatricians, general practitioners (GPs), and nurse specialists to assess knowledge on the subject. RESULTS A total of 96 HCPs completed the questionnaire. The nurse specialists had the highest score in identifying that oxybutynin was the drug most likely to cross the blood-brain barrier (BBB). The urogynaecologists had the highest score in identifying that trospium chloride was least likely to cross the BBB, whereas the GPs had the lowest score. Solifenacin was the most popular anticholinergic drug prescribed in the elderly without dementia. Trospium chloride was the most popular drug prescribed in the elderly with dementia. CONCLUSIONS We have found that knowledge is lacking amongst all our HCPs, but especially amongst our first-line doctors, our GPs. Education is key in developing knowledge and safe prescribing, to improve the care we give to our patients.

Abstract
BACKGROUND Lower Urinary Tract Symptoms (LUTS) in men are a common clinical problem in urology and have been historically strictly linked to benign prostatic hyperplasia (BPH), which may lead to bladder outlet obstruction (BOO). New molecules have been approved and have entered the urologists' armamentarium, targeting new signaling pathways and tackling specific aspects of LUTS. Objective of this review is to summarize the evidence regarding the new medical therapies currently available for male non-neurogenic LUTS, including superselective α1-antagonists, PDE-5 inhibitors, anticholinergic drugs and intraprostatic onabotulinum toxin injections. METHODS The National Library of Medicine Database was searched for relevant articles published between January 2006 and December 2015, including the combination of "BPH", "LUTS", "medical" and "new". Each article's title, abstract and text were reviewed for their appropriateness and their relevance. One hundred forty eight articles were reviewed. RESULTS Of the 148 articles reviewed, 92 were excluded. Silodosin may be considered a valid alternative to non-selective α1-antagonists, especially in the older patients where blood pressure alterations may determine major clinical problems and ejaculatory alterations may be not truly bothersome. Tadalafil 5 mg causes a significant decrease of IPSS score with an amelioration of patients' QoL, although with no significant increase in Qmax. Antimuscarinic drugs are effective on storage symptoms but should be used with caution in patients with elevated post-void residual. Intraprostatic injections of botulinum toxin are well-tolerated and effective, with a low rate of adverse events; however profound ameliorations were seen also in the sham arms of RCTs evaluating intraprostatic injections. CONCLUSION New drugs have been approved in the last years in the medical treatment of BPH-related LUTS. Practicing urologists should be familair with their pharmacodynamics and pharmacokinetics.

Abstract
Traditionally, the treatment of overactive bladder syndrome has been based on the use of oral medications with the purpose of reestablishing the detrusor stability. The recent better understanding of the urothelial physiology fostered conceptual changes, and the oral anticholinergics - pillars of the overactive bladder pharmacotherapy - started to be not only recognized for their properties of inhibiting the detrusor contractile activity, but also their action on the bladder afference, and therefore, on the reduction of the symptoms that constitute the syndrome. Beta-adrenergic agonists, which were recently added to the list of drugs for the treatment of overactive bladder, still wait for a definitive positioning - as either a second-line therapy or an adjuvant to oral anticholinergics. Conservative treatment failure, whether due to unsatisfactory results or the presence of adverse side effects, define it as refractory overactive bladder. In this context, the intravesical injection of botulinum toxin type A emerged as an effective option for the existing gap between the primary measures and more complex procedures such as bladder augmentation. Sacral neuromodulation, described three decades ago, had its indication reinforced in this overactive bladder era. Likewise, the electric stimulation of the tibial nerve is now a minimally invasive alternative to treat those with refractory overactive bladder. The results of the systematic literature review on the oral pharmacological treatment and the treatment of refractory overactive bladder gave rise to this second part of the review article Overactive Bladder - 18 years, prepared during the 1st Latin-American Consultation on Overactive Bladder.

Abstract
The prevalence of overactive bladder (OAB) increases with age. Degeneration of the central nervous system in the elderly has been proposed as one of the pathogenic factors of OAB. Antimuscarinic therapy is effective in the treatment of OAB; however, intolerable systemic adverse events and cognitive dysfunction during treatment with nonselective antimuscarinic agents is of growing concern in elderly patients. The newly developed beta-3 adrenoceptor agonist mirabegron does not adversely affect flow rate and detrusor pressure, and its therapeutic efficacy and tolerability are similar in patients aged > 65 years and > 75 years, suggesting it might be the therapeutic choice in older patients with OAB. Nocturia can cause sleep deprivation at night and increase daytime sleepiness and loss of energy in the elderly. Desmopressin add-on therapy is effective in improving nocturia and storage symptoms. However, elderly patients with a baseline serum sodium level below the normal range are at high risk of developing significant hyponatremia.

Abstract
OBJECTIVE Overactive bladder (OAB) is a particular challenge to treat in older adults with co-morbid conditions taking multiple medications. Antimuscarinics (e.g., solifenacin, fesoterodine) and β3-adrenergic receptor agonists (mirabegron) are similarly efficacious; however, antimuscarinics may be associated with side effects that result in poor persistence and contribute to anticholinergic burden, particularly in those taking other medications with anticholinergic properties. With a mechanism of action distinct from antimuscarinics, mirabegron has a different tolerability profile and does not contribute to anticholinergic burden. The objective of this review was to compare and contrast the tolerability profiles of antimuscarinics and mirabegron in older patients to inform practice. METHODS Prospective trials or retrospective subgroup analyses of antimuscarinics for the treatment of OAB in older patients were identified through a search of PubMed. Tolerability data and results of subgroup analyses of mirabegron in patients aged ≥65 and ≥75 years from a pooled analysis of three trials each of 12 weeks and a 1 year trial are described. RESULTS Anticholinergic adverse events (AEs) including dry mouth and constipation were more frequent with antimuscarinics versus mirabegron. In patients aged ≥65 years, dry mouth occurred with a six-fold higher incidence with tolterodine extended-release (ER) 4 mg than with mirabegron 25 mg or 50 mg over 12 weeks, and a three-fold higher incidence with tolterodine ER than mirabegron 50 mg over 1 year. Mirabegron had a low incidence of central nervous system effects. A systematic review of the cardiovascular safety profile of mirabegron has not identified any clinically significant effects on blood pressure or pulse rate at therapeutic doses amongst patients aged ≥65 years. CONCLUSIONS Mirabegron has a more favorable tolerability profile than antimuscarinics amongst older patients and may provide an improved benefit-to-risk ratio and therefore be considered as an alternative to antimuscarinics for older patients.
