Abstract
BACKGROUND Around 16% of adults have symptoms of overactive bladder (OAB; urgency with frequency and/or urge incontinence), with prevalence increasing with age. Anticholinergic drugs are commonly used to treat this condition. This is an update of a Cochrane Review first published in 2002 and last updated in 2006. OBJECTIVES To assess the effects of anticholinergic drugs compared with placebo or no treatment for treating overactive bladder syndrome in adults. SEARCH METHODS We searched the Cochrane Incontinence Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, ClinicalTrials.gov, WHO ICTRP and handsearching of journals and conference proceedings (searched 14 January 2020), and the reference lists of relevant articles. We updated this search on 3 May 2022, but these results have not yet been fully incorporated. SELECTION CRITERIA We included randomised or quasi-randomised trials in adults with overactive bladder syndrome that compared an anticholinergic drug alone with placebo treatment. DATA COLLECTION AND ANALYSIS Two review authors independently assessed eligibility and extracted data from the included studies, including an assessment of the risk of bias. We assessed the certainty of the body of evidence using the GRADE approach. We processed data as described in the Cochrane Handbook for Systematic Reviews of Interventions. MAIN RESULTS We included 104 studies, 71 of which were new or updated for this version of the review. Although 12 studies did not report the number of participants, there were 47,106 people in the remainder of the included studies. The majority of the studies had insufficient information to allow judgement of risk of bias and we judged them to be unclear for all domains. Nine anticholinergic drugs were included in these studies: darifenacin; fesoterodine; imidafenacin; oxybutynin; propantheline; propiverine; solifenacin; tolterodine and trospium. No studies were found that compared anticholinergic drugs to no treatment. At the end of the treatment period, anticholinergics may slightly increase condition-specific quality of life (mean difference (MD) 4.41 lower, 95% confidence interval (CI) 5.28 lower to 3.54 lower (scale range -100 to 0); 12 studies, 6804 participants; low-certainty evidence). Anticholinergics are probably better than placebo in terms of patient perception of cure or improvement (risk ratio (RR) 1.38, 95% CI 1.15 to 1.66; 9 studies, 8457 participants; moderate-certainty evidence), and the mean number of urgency episodes per 24-hour period (MD 0.85 lower, 95% CI 1.03 lower to 0.67 lower; 23 studies, 16,875 participants; moderate-certainty evidence). Compared to placebo, anticholinergics may result in an increase in dry mouth adverse events (RR 3.50, 95% CI 3.26 to 3.75; 66 studies, 38,368 participants; low-certainty evidence), and may result in an increased risk of urinary retention (RR 3.52, 95% CI 2.04 to 6.08; 17 studies, 7862 participants; low-certainty evidence). Taking anticholinergics may be more likely to lead to participants withdrawing from the studies due to adverse events (RR 1.37, 95% CI 1.21 to 1.56; 61 studies, 36,943 participants; low-certainty evidence). However, taking anticholinergics probably reduces the mean number of micturitions per 24-hour period compared to placebo (MD 0.85 lower, 95% CI 0.98 lower to 0.73 lower; 30 studies, 19,395 participants; moderate-certainty evidence). AUTHORS' CONCLUSIONS The use of anticholinergic drugs by people with overactive bladder syndrome results in important but modest improvements in symptoms compared with placebo treatment. In addition, recent studies suggest that this is generally associated with only modest improvement in quality of life. Adverse effects were higher with all anticholinergics compared with placebo. Withdrawals due to adverse effects were also higher for all anticholinergics except tolterodine. It is not known whether any benefits of anticholinergics are sustained during long-term treatment or after treatment stops.

Choosing the Most Efficacious and Safe Oral Treatment for Idiopathic Overactive Bladder: A Systematic Review and Network Meta-analysis. Eur Urol Focus 2021; 8:1072-1089. [PMID: 34563481 DOI: 10.1016/j.euf.2021.08.011] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Revised: 08/19/2021] [Accepted: 08/31/2021] [Indexed: 11/19/2022]
Abstract
CONTEXT The choice of the most efficacious drug for patients with idiopathic overactive bladder (IOAB) remains challenging. OBJECTIVE The aim of this network meta-analysis was to determine the most efficacious oral antimuscarinic or β-adrenoceptor agonist accounting for adverse events for the management of IOAB. EVIDENCE ACQUISITION A comprehensive electronic search was done in MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, and Ovid for studies in any language in February 2021 considering the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. We included all randomized controlled trials assessing oral antimuscarinics or β-adrenoceptor agonists for the treatment of IOAB. We determined the effect of specific bothersome symptoms separately. EVIDENCE SYNTHESIS Fifty-four articles were included in our analysis. The most efficacious agents considering the evaluated outcomes were oxybutynin 15 mg/d in reducing incontinence episodes, imidafenacin 0.5 mg/d together with solifenacin 10 and 5 mg/d in reducing micturition episodes, fesoterodine 4 and 8 mg/d as well as solifenacin 10 mg/d in reducing urgency episodes, imidafenacin 0.5 mg/d and solifenacin 10 mg/d in reducing urgency urinary incontinence episodes, and solifenacin 10 mg/d, vibegron 50 mg/d, and fesoterodine 8 mg/d in improving the voided volume. Gastrointestinal problems, especially due to antimuscarinic agents, were the most prevalent adverse events. CONCLUSIONS Taken together, there is only minimal difference between the efficacy of oral antimuscarinics and that of β-adrenoceptor agonists. Although finding the best medication for all is impossible, finding the best treatment for every individual patient can be done by considering the efficacy of a medicine for the most bothersome symptom(s) in balance with drug-specific adverse events. PATIENT SUMMARY This study aimed to find the most efficient oral medication to treat overactive bladder, taking into consideration the adverse events. Based on our study, there is a minimal difference in the efficacy between the two major drug classes used to treat overactive bladder. Gastrointestinal problems were the most common adverse events in medical treatment of overactive bladder. Selection of the best treatment is possible through shared decision-making between the doctor and the patient based on the patient's most bothersome symptom. We provide a framework for physicians to facilitate shared decision-making with each individual patient.

Nocebo Response in the Pharmacological Management of Overactive Bladder: A Systematic Review and Meta-analysis. Eur Urol Focus 2020; 7:1143-1156. [PMID: 33153953 DOI: 10.1016/j.euf.2020.10.010] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2020] [Revised: 09/20/2020] [Accepted: 10/21/2020] [Indexed: 12/18/2022]
Abstract
CONTEXT The role of a nocebo response in managing urology patients is unclear. OBJECTIVE To assess the nocebo response in randomized placebo-controlled overactive bladder (OAB) trials of pharmacological treatment by investigating the adverse events in the placebo arms. EVIDENCE ACQUISITION PubMed, Scopus, Embase, and Cochrane Central Register of Controlled Trials were searched to identify potential randomized controlled trials published from 1998 to November 2019. After evaluating the risk of bias in the selected studies, all selected full-text articles were included due to their overall acceptable quality. We extracted the event rate of the most commonly reported adverse events in the placebo arms of OAB trials, and finally, we performed a meta-analysis to calculate the cumulative rate of certain adverse events. The primary outcomes were the event rate of adverse events in the placebo arms of OAB trials of pharmacological treatment, and differences in adverse events in the placebo groups based on drug type and routes of administration. EVIDENCE SYNTHESIS After a systematic search and risk of bias assessment, 57 trials comprising 15 446 patients were included in this systematic review. We selected 13 commonly reported adverse events for the meta-analysis. Owing to the possible differences in study samples and design, we used a random model for the analysis. The average age of the patients was 59.5 yr and 79.8% were female. Dry mouth was the most commonly evaluated adverse event reported in 57 studies comprising 15 324 patients; the mean event rate was 4.9% (95% confidence interval [CI] 0.042-0.057, p < 0.001). Constipation was the second most commonly reported adverse event in 49 studies comprising 14 556 patients; the mean event rate of constipation was 2.6% (95% CI 0.022-0.031, p < 0.001). The event rate of headache was evaluated in 33 studies comprising 10 202 patients, with a mean event rate of 3.1% (95% CI 0.026-0.037, p < 0.001). CONCLUSIONS Dry mouth, constipation, headache, and nasopharyngitis were the most prevalent events in the included studies. The nocebo response plays a statistically significant role in causing and/or facilitating adverse events. Health care providers should have a better understanding of the positive and negative expectations associated with therapies to achieve the best possible outcomes for each individual patient. Finally, identification of the real effect of nocebo requires studies that also include a no-treatment arm. Research could help us better understand and potentially modify the nocebo response. PATIENT SUMMARY In this meta-analysis of 57 studies comprising 15 446 patients, we reviewed the adverse events extracted from the placebo arms of randomized controlled trials studying therapies for overactive bladder. Dry mouth, constipation, headache, and urinary tract infection were the most common adverse events. Adverse events varied based on the drug type and the route of administration. Negative expectations from the therapy and giving verbal information to the patient can cause/alleviate adverse events.

Abstract
Objective To evaluate the long-term efficacy of mirabegron add-on therapy in patients with spinal cord injury (SCI) based on an urodynamic study. Methods This retrospective study involved a chart audit of individuals with SCI who underwent two consecutive urodynamic studies between April 1, 2015 and April 1, 2018. After adding 50 mg of mirabegron once a day to the pre-existing antimuscarinic therapy for a period of, at least 6 months, the following variables were analyzed: change in cystometric capacity, change in bladder compliance, change in maximal detrusor pressure, change in reflex volume, and presence of significant leakage during filling cystometry. Results A total of 31 participants with a mean age of 41±15 years were included in the analysis. A significant increase in cystometric capacity (mean, 362 to 424 mL; p=0.03), reflex volume (mean, 251 to 329 mL; p=0.02), and bladder compliance (median, 12 to 18 mL/cmH2O; p=0.04) was observed. The presence of leakage during filling cystometry was significantly reduced (29% to 10%; p=0.03). Likewise, a non-significant decrease in the change in maximal detrusor pressure was observed (mean, 31 to 27 cmH2O; p=0.39). Conclusion Adding mirabegron to conventional antimuscarinics further improved urodynamic parameters in patients with chronic SCI, and sustained efficacy was observed in long-term use.

Abstract
BACKGROUND Medication-induced salivary gland dysfunction (MISGD), xerostomia (sensation of oral dryness), and subjective sialorrhea cause significant morbidity and impair quality of life. However, no evidence-based lists of the medications that cause these disorders exist. OBJECTIVE Our objective was to compile a list of medications affecting salivary gland function and inducing xerostomia or subjective sialorrhea. DATA SOURCES Electronic databases were searched for relevant articles published until June 2013. Of 3867 screened records, 269 had an acceptable degree of relevance, quality of methodology, and strength of evidence. We found 56 chemical substances with a higher level of evidence and 50 with a moderate level of evidence of causing the above-mentioned disorders. At the first level of the Anatomical Therapeutic Chemical (ATC) classification system, 9 of 14 anatomical groups were represented, mainly the alimentary, cardiovascular, genitourinary, nervous, and respiratory systems. Management strategies include substitution or discontinuation of medications whenever possible, oral or systemic therapy with sialogogues, administration of saliva substitutes, and use of electro-stimulating devices. LIMITATIONS While xerostomia was a commonly reported outcome, objectively measured salivary flow rate was rarely reported. Moreover, xerostomia was mostly assessed as an adverse effect rather than the primary outcome of medication use. This study may not include some medications that could cause xerostomia when administered in conjunction with others or for which xerostomia as an adverse reaction has not been reported in the literature or was not detected in our search. CONCLUSIONS We compiled a comprehensive list of medications with documented effects on salivary gland function or symptoms that may assist practitioners in assessing patients who complain of dry mouth while taking medications. The list may also prove useful in helping practitioners anticipate adverse effects and consider alternative medications.

Abstract
Nocturia, or awakening one or more times to void at night, becomes clinically significant with two or more voids a night. In the past, nocturia has typically been viewed as a symptom of benign prostatic hyperplasia and/or overactive bladder syndrome. However, newer evidence supports that this is no longer just a symptom but a medical condition that warrants further workup and treatment given its effect on quality of life. The negative effects of nocturia include sleep fragmentation, decreased productivity at work, and increased risk of falls and fractures. A workup to find the underlying cause of nocturia will help guide treatment, which may include pharmacologic agents.

Abstract
Strategies to manage nocturia include lifestyle modifications and treatment with alpha-blockers, antimuscarinic therapies, and antidiuretics. The concept of achieving success should not be limited to reduction of nighttime voids; it should ideally include proof of improvement of conditions generally associated with nocturia, such as falls, quality of life, and overall health. Few studies have looked specifically at parameters other than nocturnal voids, such as sleep latency, first undisturbed sleep period (FUSP), and total sleep time, including their clinical relevance to patient well-being. Lifestyle modifications, such as voiding before bedtime, limiting caffeine and alcohol, and adjusting medication timing, may be initially effective in mild cases of nocturia. Statistically significant reductions in voiding have been reported with antimuscarinic agents and alpha-blockers as initial therapy, but these reductions generally are not clinically relevant. The antidiuretic therapy desmopressin acetate, a selective vasopressin receptor 2 agonist, is effective in adults with nocturia associated with nocturnal polyuria; however, hyponatremia can occur. The newest formulation-desmopressin orally disintegrating sublingual tablet (ODST)--has greater bioavailability; thus, lower doses can be used, potentially reducing hyponatremia risk. A phase 3 study demonstrated statistically significant reductions in nocturnal voids for desmopressin ODST 50 and 100 µg versus placebo (-1.18 and -1.43 vs. -0.86; P = 0.02 and P < 0.0001, respectively) in patients with nocturia. Treatment was well-tolerated, and low-dose desmopressin ODST was associated with statistically significant increases in duration of FUSP. Development of a validated composite endpoint may help clinicians identify and compare strategies for treating nocturia.

Abstract
UNLABELLED WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Antichollnergic agents are anticipated to diminish storage symptoms, as well as nocturia. Nevertheless, the effect of this treatment on polyuria related to nocturia is not clear. By subgroup analysis of the data set from a phase III clinical trial of antimuscarinic agent for OAB patients in Japan, imidafenacin was found to improve nocturia with a reduction in nocturnal polyuria. This study adds the effects and underlying mechanism of antimuscarinic agents decreasing urine production through inhibition of C-fibre in the bladder of water-leaded rats. OBJECTIVE To evaluate the effects and underlying mechanisms of antimuscarinic agents used to decrease in urine production in water-loaded rats. SUBJECTS AND METHODS Urine production was measured using a cystostomy catheter in female Sprague-Dawley rats every 2 h. The effect of the antimuscarinic agents atropine, tolterodine and imidafenacin on urine production was investigated under water-loaded conditions, which were induced by i.p. injection of 15 mL saline. Blood samples were collected to determine the levels of antidiuretic hormone (ADH), aldosterone (ALD), atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) before, and 2 and 8 h after, antimuscarinic agent administration. To induce desensitization of C-fibre afferent nerves, resiniferatoxin (RTX)was injected s.c. or intravesically 2 days before experiments. RESULTS Urine production increased and reached its maximum 2 h after 15 mL saline injection. Imidafenacin and tolterodine decreased urine production in water-loaded rats, but ADH, ALD, ANP and BNP levels were not different between imidafenacin-treated and vehicle-treated rats. The inhibitory effect on urine production was not found in RTX-treated rats. Atropine did not reduce urine production. CONCLUSION These results suggest that antimuscarinic agents decrease urine volume through C-fibres in the bladder; thus, antimuscarinics with inhibitory effects on C-fibres could be beneficial for nocturia with nocturnal polyuria.

Abstract
A consensus statement published in 2011 summarised current research, clinical approaches, and treatment options for nocturia. Since that time, new research has refined our understanding of nocturia in clinically important ways and new evidence has been presented on the efficacy and outcomes of several treatment methods for this underreported, infrequently recognised, and undertreated problem in adults. This paper provides updated guidance to clinicians in light of recent advances in the field.

Abstract
Nocturia is a prevalent highly bothersome urinary symptom that may significantly detriment the health and well-being of sufferers. It is characterized by waking at night to void, each void preceded and followed by sleep, hence leading to fragmentation of sleep and day-time tiredness. This may result in reduced productivity in the workplace, which contributes to the significant burden to the wider society that nocturia incurs. Nocturia was traditionally viewed as one of the many urinary tract symptoms that occur due to lower urinary tract dysfunction. However, recently it has been recognized that due to its multi-factorial aetio-pathogenesis, nocturia should be viewed as distinct clinical condition in its own right. Careful assessment of the nocturic patient is essential so that treatment strategies are guided by the likely causes. Much research is currently being undertaken into the underlying causes and the optimal management approaches. This review will explore the contemporary status of research on nocturia with a focus on the current and newly available pharmacotherapies.

Abstract
Patients with nocturia are often referred to urologists, but the underlying cause most often lies outside the urinary tract. Nocturia should be considered a systemic disorder and investigated and treated as such. Comprehensive assessment of the symptoms, optimally including a frequency volume chart, can help to determine the potential underlying cause and help to direct the patient to the most suitable medical professional for further management.

Abstract
Overactive bladder syndrome (OAB) is a chronic condition that has an impact on patients' daily activities and health-related quality of life (HRQL). Anticholinergic therapy is often prescribed following insufficient results with behaviour modification alone; however, rates of treatment discontinuation are consistently high. This study systematically reviewed persistence and adherence data in patients with OAB treated with anticholinergic therapy. A search focused on the intersection of OAB, persistence/adherence, and anticholinergic therapy was conducted in MEDLINE and EMBASE. Articles published after 1998 were reviewed and selected for inclusion based on prespecified criteria. A total of 147 articles and two abstracts were included in the review. Results from 12-week clinical trials showed high rates of discontinuation, ranging from 4% to 31% and 5% to 20% in treatment and placebo groups, respectively. Unsurprisingly, rates of discontinuation found in medical claims studies were substantially higher, with 43% to 83% of patients discontinuing medication within the first 30 days and rates continuing to rise over time. Findings from medical claims studies also suggest that over half of patients never refill their initial prescription and that adherence levels tend to be low, with mean/median medication possession ratio (MPR) values ranging from 0.30 to 0.83. The low levels of persistence and adherence documented in this review reveal cause for concern about the balance between the efficacy and tolerability of anticholinergic agents. Strategies should be identified to increase persistence and adherence. New agents and non-pharmacologic alternatives with good efficacy and minimal side effects should be explored.

Abstract
INTRODUCTION Since urgency is key to the overactive bladder syndrome, we have reviewed the mechanisms underlying how bladder filling and urgency are sensed, what causes urgency and how this relates to medical therapy. MATERIALS AND METHODS Review of published literature. RESULTS As urgency can only be assessed in cognitively intact humans, mechanistic studies of urgency often rely on proxy or surrogate parameters, such as detrusor overactivity, but these may not necessarily be reliable. There is an increasing evidence base to suggest that the sensation of ‘urgency’ differs from the normal physiological urge to void upon bladder filling. While the relative roles of alterations in afferent processes, central nervous processing, efferent mechanisms and in intrinsic bladder smooth muscle function remain unclear, and not necessarily mutually exclusive, several lines of evidence support an important role for the latter. CONCLUSIONS A better understanding of urgency and its causes may help to develop more effective treatments for voiding dysfunction.

Abstract
BACKGROUND The overactive bladder syndrome is a common condition affecting approximately 12% of men and women. It is extremely disturbing with a great impact on quality of life. Its treatment involves a combination of behavioural and pharmacological therapy. The latter includes antimuscarinic drugs such as tolterodine. OBJECTIVE To review the safety and efficacy of tolterodine in the treatment of overactive bladder in comparison with other available antimuscarinic agents. METHODS A Pubmed search was carried out differentiating randomised, clinical trials; longitudinal, retrospective studies; and metanalysis on the use of tolterodine for overactive bladder treatment. In the comparison with other antimuscarinic agents, only randomised, clinical trials were considered. RESULTS/CONCLUSION Tolterodine is available as immediate- or extended-release formulations. It has been extensively evaluated with long-term, randomised trials for safety and efficacy showing a significant improvement in overactive bladder symptoms with an excellent tolerability profile.

Abstract
PURPOSE We validated a simple scale to measure urinary urgency. MATERIALS AND METHODS The new 10-item scale was validated using data from experiments using a single group repeated measure design. A total of 475 patients, including 411 females and 64 males, with a mean age of 57.3 years who had been diagnosed with overactive bladder were treated with a bladder retraining regimen and antimuscarinic agent (10 mg oxybutynin controlled release per night or 4 mg tolterodine slow release per night). At each visit patient urge symptoms were recorded by the scale. Reported average daily frequency and incontinence episodes were also recorded. Of patients who were not satisfied with the symptoms 130 had 25 mg imipramine per night added to their prescription and in 130 treatment was changed to 10 mg solifenacin per night. RESULTS Construct validity was tested by comparing the urgency scale to frequency and to incontinence (Spearman's rank correlation coefficient r = 0.38, p <0.001 and r = 0.15, p <0.001, respectively). Internal consistency showed Cronbach's alpha = 0.83. Test-retest reliability was determined in 30 patients and interobserver reliability was determined in 58 (Pearson's r = 0.99, p <0.001 and r = 0.99, p <0.001, respectively). Internal responsiveness in the imipramine add-on study in 130 patients showed a standardized response mean of 0.6 (p <0.001) and in the solifenacin swap study in 130 it showed a standardized response mean of 0.69, while external responsiveness showed a standardized response mean of 0.69 (each p <0.001). CONCLUSIONS This scale succeeded in all validation studies. This new scale may prove useful for measuring between-drug differences in efficacy and for monitoring treatment responses in patients with overactive bladder. It now must be tested in a proper double-blind, randomized, controlled trial.

Abstract
OBJECTIVES Patients with neurogenic bladder dysfunction demonstrate an insufficient treatment outcome under dosage-escalated monotherapy. With the objectives of continence and normalised bladder pressure, safe and tolerable non-invasive treatment alternatives were evaluated by using combined antimuscarinics. METHODS Twenty-seven patients who were previously registered in a doubled antimuscarinics study were enrolled in this study. The patients demonstrated urodynamic-proven neurogenic bladder dysfunction with incontinence, reduced bladder capacity, and increased intravesical pressure, resulting from spinal cord injury (n=21); spinal cord dysplasia (myelomeningocele; n=3); multiple sclerosis (n=2), and viral encephalomyelitis (n=1). On the basis of the initial study treatment, they were allocated into three groups and treated with two antimuscarinics. Before enrollment, at 4 wk, and at 6 mo, patients underwent urodynamics and recorded bladder diaries, including side-effects. RESULTS In all three groups, significant changes were noted at the 4-wk follow-up. Incontinence events decreased from an average of 7 to 1 event per day. The average median bladder capacity (180-393 ml) and reflex volume (125-335 ml) increased; detrusor compliance also improved (average, 15-33 ml/cm H2O). Seven patients reported side-effects; two discontinued the successful treatment. Two other patients did not reach satisfactory amelioration of the detrusor dysfunction. CONCLUSION With combined high-dosage antimuscarinic medications, 85% of the patients who previously demonstrated unsatisfactory outcome with dosage-escalated monotherapy were treated successfully. The appearance of side-effects was comparable to that of normal-dosed antimuscarinics. Further studies are required to investigate the long-term pharmacological and physiological background of our findings.

Abstract
Muscarinic receptor antagonists are used clinically for their therapeutic peripheral effects on bladder function. However, these agents may also act on central muscarinic receptors, especially in individuals with compromised blood-brain barrier function. We compared the effects of atropine and tolterodine, agents that do and do not readily cross the blood-brain barrier, respectively, administered peripherally (intravenous [i.v.]) and centrally (intracerebroventricular [i.c.v.]) on cystometrography in conscious rats after cerebral infarction induced by middle cerebral artery occlusion or sham surgery. We hypothesized that tolterodine would produce greater improvement in bladder capacity and less impairment in bladder contractility and that the effects of both agents would be greater in rats with cerebral infarction and sham-operated rats after peripheral administration, but that tolterodine and atropine would exert similar effects after central administration. Bladder capacity was markedly reduced following cerebral infarction. Low-dose i.v. tolterodine (<or=20 nmol/kg) significantly reversed this effect without altering residual volume or bladder contraction pressure. Low-dose i.v. atropine (2 nmol/kg) had no effect on bladder capacity but significantly decreased bladder contraction pressure. Higher doses of i.v. atropine (>or=20 nmol/kg) significantly increased bladder capacity but also significantly increased residual volume and decreased bladder contraction pressure. Tolterodine was significantly more efficacious than atropine in increasing bladder capacity, whereas atropine produced significantly greater increases in residual volume and reductions in bladder contraction pressure; these treatment group differences were also observed in sham-operated animals. Tolterodine and atropine administered i.c.v. significantly increased bladder capacity following cerebral infarction or sham surgery; however, this was accompanied by significantly increased residual volume and decreased bladder contraction time. The decrease in bladder contraction time was significantly smaller after tolterodine vs atropine. Peripherally acting muscarinic receptor antagonists may be preferable to centrally acting agents for minimizing adverse events, such as incomplete bladder emptying, even in individuals with compromised blood-brain barrier function.

Abstract
Solifenacin is an antimuscarinic agent, administered once daily, which has been newly approved for the treatment of overactive bladder (OAB). Solifenacin administered at 5- and 10-mg once-daily doses shows efficacy for all the symptoms of OAB in both 'wet' and 'dry' patients, including improvements in patient quality of life and satisfaction. These improvements are observed as early as week 2 of treatment and are maintained over 12-week and 1-year time periods, without being compromised by the age or gender of the patient. Solifenacin demonstrates a favourable tolerability profile, with mild dry mouth as the most common adverse event associated with its use, both at the 5- and 10-mg doses; this allows for flexibility in the dosing regimen, in which physicians can administer solifenacin 5 mg, with the option to safely increase the dose to 10 mg if necessary based on the severity of patient's symptoms. The favourable efficacy and safety profile of solifenacin, coupled with its dose flexibility, are consistent with solifenacin being a convenient treatment option for patients with OAB.
