Sahai A, Robinson D, Abrams P, Wein A, Malde S. What is the best first choice oral drug therapy for OAB? Neurourol Urodyn 2024; 43:1328-1336. [PMID: 38270332 DOI: 10.1002/nau.25397] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2023] [Revised: 12/29/2023] [Accepted: 01/03/2024] [Indexed: 01/26/2024]
Abstract
AIMS The management of overactive bladder (OAB) involves lifestyle changes and conservative measures in the first instance with the use of liquid/dietary advice, weight loss, and bladder training. Thereafter oral pharmacotherapy is instigated in symptomatic patients. Antimuscarinics and beta 3 agonists form the main classes of drug therapy in this field. Views on what is the best first line OAB treatment is changing based on recent evidence and adverse event profiles of these medications. METHODS At the ICI-RS meeting 2023, Bristol, UK this topic was discussed and debated as a proposal. The following article summarizes the concepts presented that day as well as the interactive discussion that took place thereafter. RESULTS OAB guidelines are moving in many circumstances to an either antimuscarinic or beta 3 agonist approach based on patient factors. Several studies have raised concerns on the long-term impact of antimuscarinics, in relation to cognition, dementia, cardiovascular events, and mortality all related to antimuscarinic load. Neither antimuscarinics nor beta 3 agonists have good persistence and adherence rates in the medium to long term. Several barriers also exist to prescribing including guidelines recommending utilizing drugs with the lowest acquisition cost and "step therapy." A newer approach to managing OAB is personalized therapy in view of the many possible etiological factors and phenotypes. These concepts are highlighted in this article. CONCLUSIONS Current oral pharmacotherapy in managing OAB is limited by adverse events, adherence and persistence problems. Both antimuscarinics and beta 3 agonists are efficacious but most clinical trials demonstrate significant placebo effects in this field. Personalizing treatment to the individual seems a logical approach to OAB. There is a need for better treatments and further studies are required of existing treatments with high quality longer term outcomes.

Abstract
BACKGROUND Millions of Americans are burdened by overactive bladder (OAB) syndrome and the psychogenic and economic hardships that accompany it. Several theories attempt to explain OAB as a neurogenic dysfunction, myogenic dysfunction, urothelial dysfunction, or decreased expression of a channel protein secondary to bladder outlet obstruction. Given that the etiology of OAB is a working theory, the management of OAB is also an evolving subject matter in medicine. There are uncertainties surrounding the pathophysiology of OAB, the strength of a clinical diagnosis, and accurate reporting because of the disease's stigma and decreased use of health care. DATA SOURCES This is a narrative review that used PubMed, Google Scholar, Medline, and ScienceDirect to review literature on current and future OAB therapies. RESULTS Currently, first-line treatment for OAB is behavioral therapy that uses lifestyle modifications, bladder-control techniques, and psychotherapy. Second-line therapy includes antimuscarinic agents or beta 3 adrenergic agonists, and studies have shown that combination therapy with antimuscarinics and beta 3 adrenergic agonists provides even greater efficacy than monotherapy. Third-line therapies discussed include onabotulinumtoxinA, posterior tibial nerve stimulation, and sacral neuromodulation. OnabotulinumtoxinA has been FDA-approved as a nonpharmaceutical treatment option for refractory OAB with minimal side effects restricted to the urinary tract. Posterior tibial nerve modulation and sacral neuromodulation are successful in treating refractory OAB, but the costs and complication rates make them high-risk procedures. Therefore, surgical intervention should be a last resort. Estrogen therapy is effective in alleviating urinary incontinence in postmenopausal women, consistent with the association between estrogen deficiency and genitourinary syndrome. Potassium channel activators, voltage-gated calcium channel blockers, and phosphodiesterase inhibitors look to be promising options for the future of OAB management. As new therapies are developed, individuals with OAB can better personalize their treatment to maximize their quality of life and cost-effective care.

Abstract
INTRODUCTION Overactive bladder syndrome is a common chronic condition with a significant impact on quality of life and economic burden. Persistence with pharmacologic therapy has been limited by efficacy and side effects. A greater understanding of the pathophysiology of overactive bladder has led to the initial evaluation of several drugs affecting ion channels, the autonomic nervous system, and enzymes which may provide useful alternatives for the management of overactive bladder. AREAS COVERED A comprehensive review was performed using PubMed and Cochrane databases as well as reviewing clinical trials in the United States. The current standard of care for overactive bladder will be discussed, but this paper focuses on investigational drugs currently in preclinical studies and phase I and II clinical trials. EXPERT OPINION Current therapies for overactive bladder have limitations in efficacy and side effects. A greater understanding of the pathophysiology of overactive bladder has identified the role(s) of other pathways in the overactive bladder syndrome. Targeting alternative pathways including ion channels and enzymes may provide alternative therapies of overactive bladder and a more tailored approach to the management of overactive bladder.

Abstract
Incontinence is defined by either ICS 2002 or IUGA/ICS 2010 as the involuntary loss of urine and includes urgency urinary incontinence (UUI), stress urinary incontinence (SUI) or mixed urinary incontinence (MUI). It has a high worldwide prevalence with an associated impact on quality of life. Despite existing management options for the management of urinary incontinence, patients continue to be troubled by symptoms or side effects of existing treatment. There is therefore a requirement for ongoing research into treatment options for the management of UUI and SUI, that are more effective and tolerable to patients. Advances in treatment of UUI include a more selective beta 3 agonist, Vibegron, which has less impact on cardiac function than Mirabegron. Hormonal treatment, including Ospemifene and Prasterone, may improve GSM and in turn symptoms of UUI. There are advances in the types of neuromodulators available, including those that are rechargeable at home and are MRI safe. Laser has shown promising initial results. There is developing interest in the microbiome, and how this may impact future treatment modalities. Advances in treatment of SUI include the use of mobile health applications to support delivery of pelvic floor muscle training. Litoxetine, a selective serotonin reuptake inhibitor, has shown promising results at phase III trials. Functional magnetic stimulation is being developed to improve contractility of pelvic floor muscles. We also discuss interventions that improve tissue elasticity and regeneration, such as platelet rich plasma, autologous stem cell transplantation, laser therapy and radiofrequency treatment, which show short term benefits.

Abstract
The aim of this debate article is to discuss whether effective treatments are available for mixed urinary incontinence (MUI). Because patients with MUI have both stress and urgency urinary incontinence (SUI and UUI) episodes and current treatment guidelines currently recommend treating the predominant symptom first, this article presents standard and emerging treatments for both SUI and UUI before discussing how well these treatments meet the medical needs of patients with MUI. Standard treatments presented include noninvasive options such as lifestyle changes and pelvic floor exercises, pharmacological agents, and surgery. Treatment of all three types of urinary incontinence (UI) is usually initiated with noninvasive options, after which treatment options diverge based on UI subtype. Multiple pharmacological agents have been developed for the treatment of UUI and overactive bladder, whereas surgery remains the standard option for SUI and stress-predominant MUI. The divide between UUI and SUI options seems to be propagated in emerging treatments, with most novel pharmacological agents still targeting UUI and even having SUI and stress-predominant MUI as exclusion criteria for participation in clinical trials. Considering that current treatment options focus almost exclusively on treating the predominant symptom of MUI and that emerging pharmacological treatments exclude patients with stress-predominant MUI during the development phase, effective treatments for MUI are lacking both in standard and emerging practice. Ideally, agents with dual mechanisms of action could provide symptom benefit for both the stress and urgency components of MUI.

Abstract
Background Overactive bladder (OAB) is a common clinical condition for which current drug treatment comprises drugs blocking the cholinergic nerve supply, or augmenting the adrenergic nerve supply, to the detrusor muscle of the urinary bladder. Current treatments have drawbacks, including lack of efficacy and the development of adverse effects in some patients. Hence, new and better drugs for treating OAB will be clinically useful. Objective This review is meant to provide information on drugs currently undergoing preclinical or clinical trials for the treatment of OAB published in journal articles or elsewhere. Methods The cited articles were retrieved from PubMed and Google Scholar from January 1, 1990, to December 31, 2021. The search terms used were contraction or contractility, detrusor, inhibition, isolated or in vitro, in vivo, overactive bladder, and relaxant effect or relaxation. Results There are 4 classes of new drugs under various stages of development for the treatment of OAB. These are drugs acting on the autonomic nerve supply to the detrusor muscle of the urinary bladder that include the anticholinergics tarafenacin and afacifenacin and the β3 adrenoceptor agonists solabegron and ritobegron; drugs acting on ion channels in the detrusor muscle (eg, potassium channel openers and calcium channel blockers), drugs acting on cellular enzymes like phosphodiesterase-5 inhibitors and Rho kinase inhibitors, and drugs acting on miscellaneous targets (eg, pregabalin and trimetazidine). Conclusions Drugs currently used to treat OAB target only the cholinergic and adrenergic cellular signalling pathways. There are many other drugs under trial targeting other cellular pathways that may be useful for treating OAB. Their approval for clinical use might improve the treatment of patients with OAB.

Abstract
INTRODUCTION The terminology for sexual health in men with lower urinary tract (LUT) and pelvic floor (PF) dysfunction has not been defined and organized into a clinically based consensus terminology report. The aim of this terminology report is to provide a definitional document within this context that will assist clinical practice and research. METHODS This report combines the input of the members of sexual health in men with LUT and PF Dysfunction working group of the International Continence Society (ICS), assisted at intervals by external referees. Appropriate core clinical categories and a sub-classification were developed to give coding to definitions. An extensive process of 18 rounds of internal and external review was involved to exhaustively examine each definition, with decision-making by collective opinion (consensus). The Committee retained evidence-based definitions, identified gaps, and updated or discarded outdated definitions. Expert opinions were used when evidence was insufficient or absent. RESULTS A terminology report for sexual health in men with LUT and PF dysfunction, encompassing 198 (178 NEW) separate definitions, has been developed. It is clinically based with the most common diagnoses defined. Clarity and user-friendliness have been key aims to make it interpretable by practitioners and trainees in all the different speciality groups involved. Conservative and surgical managements are major additions and appropriate figures have been included to supplement and clarify the text. Emerging concepts and measurements, in use in the literature and offering further research potential, but requiring further validation, have been included as an appendix. Interval (5-10 years) review is anticipated to keep the document updated. CONCLUSION A consensus-based terminology report for sexual health in men with LUT and PF dysfunction has been produced to aid clinical practice and research. The definitions that have been adopted are those that are most strongly supported by the literature at this time or are considered clinical principles or consensus of experts' opinions.

Abstract
OBJECTIVE To evaluate the efficacy and safety of simultaneous administration of dutasteride, tadalafil and solifenacin in the treatment of benign prostatic hyperplasia (BPH) with overactive bladder symptoms and lower urinary tract obstruction in previously unsuccessfully treated men. METHODS Patients in Group A (n=97) received dutasteride 0.5 mg/day, tadalafil 2.5 mg/day, and solifenacin 2.5 mg/day; Group B (n=95) received dutasteride 0.5 mg/day, tadalafil 5 mg/day, and solifenacin 5 mg/day; Group C (n=103) received dutasteride 0.5 mg/day, tadalafil 20 mg/day, and solifenacin 10 mg/day. The functional status of the lower urinary tract was assessed using the International Prostate Symptom Score (I-PSS), Overactive Bladder Questionnaire (OABq), International Index of Erectile Function (IIEF), and Male Sexual Health Questionnaire Ejaculatory Dysfunction (MSHQ-EjD) as well as uroflowmetry. RESULTS The total score of the sexual function remained unchanged in Group B of patients 81.3 points vs. 80.2 points (p>0.05) according to MSHQ-EjD, 61.4 points vs. 51.2 points (p>0.05) according to IIEF data. The total assessment of symptoms of hyperactivity significantly decreased in Group C according to OABq data after the 4th week of the study (17.5 points vs. 26.1 points, p<0.05) and remained below the baseline until the end of the study (15.2 points). CONCLUSIONS The simultaneous administration of standard doses of dutasteride, solifenacin, and tadalafil for 3 months is safe, effective, and can be recommended for patients with BPH to reduce symptoms of obstruction and hyperactivity of the bladder and maintain sexual function.

Abstract
Pharmacological management of urinary incontinence (UI) is currently based on antimuscarinic and beta-3-agonist drugs. Botulinum toxin A detrusor injections represent an effective but more invasive alternative. This review covers the latest developments of the currently available drugs and the emerging compounds for the treatment of UI. Evidence shows that new antimuscarinics and beta-3-agonists with improved safety profiles may offer unique options to patients intolerant to currently available drugs. Combination therapy proved to be a non-invasive alternative for patients refractory to first-line monotherapy. Exciting advances are ongoing in the research to improve the efficacy/tolerability profile of botulinum toxin, through innovative routes of administration. Several new agents emerged from preclinical studies, some of which have now entered the clinical phase of development and could represent, in the coming years, a new way for the treatment of UI. Recent evidence on the existence of different overactive bladder phenotypes could be the key to tailored treatment. Rather than discovering new molecules, reaching the ability to identify the right drug for the right patient could be the real gamechanger of the future.

Abstract
Overactive bladder (OAB) syndrome is a common condition characterised by urinary
urgency, with or without urgency incontinence, frequency and nocturia, in the
absence of any other pathology. Clinical diagnosis is based upon patient
self-reported symptomology. Currently there is a plethora of treatments
available for the management of OAB. Clinical guidelines suggest treatment
via a multidisciplinary pathway including behavioural
therapy and pharmacotherapy, which can be commenced in primary care, with
referral to specialist services in those patients refractory to these
treatments. Intradetrusor botulinum A and sacral neuromodulation provide safe
and efficacious management of refractory OAB. Percutaneous tibial nerve
stimulation and augmentation cystoplasty remain available and efficacious in a
select group of patients. Unfortunately, there remains a high rate of patient
dissatisfaction and discontinuation in all treatments and thus there remains a
need for emerging therapies in the management of OAB.

Tadalafil ameliorates bladder overactivity by restoring insulin-activated detrusor relaxation via the bladder mucosal IRS/PI3K/AKT/eNOS pathway in fructose-fed rats. Sci Rep 2021; 11:8202. [PMID: 33859259 PMCID: PMC8050041 DOI: 10.1038/s41598-021-87505-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Accepted: 03/23/2021] [Indexed: 11/08/2022] Open
Abstract
The pathophysiologies of metabolic syndrome (MS) and overactive bladder (OAB) might overlap. Using fructose-fed rats (FFRs) as a rodent model of MS we investigated the effects of tadalafil (a phosphodiesterase type 5 inhibitor) on the dysregulated insulin signalling in the bladder mucosa and bladder overactivity. Micturition behaviour was evaluated. Concentration-response curves on detrusor relaxation to insulin stimulation were examined. Expression and phosphorylation of proteins in the insulin signalling pathway were evaluated by Western blotting. Levels of detrusor cGMP and urinary nitrite and nitrate (NOx) were measured. We observed FFRs exhibited metabolic traits of MS, bladder overactivity, and impaired insulin-activated detrusor relaxation in organ bath study. A high-fructose diet also impeded insulin signalling, reflected by overexpression of IRS1/pIRS1Ser307 and pIRS2Ser731 and downregulation of PI3K/pPI3KTyr508, AKT/pAKTSer473, and eNOS/peNOSSer1177 in the bladder mucosa, alongside decreased urinary NOx and detrusor cGMP levels. Tadalafil treatment restored the reduced level of mucosal peNOS, urinary NOx, and detrusor cGMP, improved the insulin-activated detrusor relaxation, and ameliorated bladder overactivity in FFRs. These results suggest tadalafil may ameliorate MS-associated bladder overactivity by restoring insulin-activated detrusor relaxation via molecular mechanisms that are associated with preservation of IR/IRS/PI3K/AKT/eNOS pathway in the bladder mucosa and cGMP production in the bladder detrusor.

Abstract
PURPOSE Overactive Bladder (OAB) is a common condition that is known to have a significant impact on Health Related Quality of Life (HRQoL). Whilst all patients will initially benefit from lifestyle modifications and behavioural therapy in the first instance drug therapy remains integral in management pathways. The purpose of this review paper is to reappraise the evidence based approach to the management of OAB in addition to exploring a new treatment algorithm for the escalation of treatment in those patients with refractory symptoms. DESIGN Literature Review RESULTS: Antimuscarinic drugs are currently the most commonly used medication although the introduction of mirabegron, a β3 agonist, has provided an alternative and also allowed combination therapy in those patients who have failed to improve on primary therapy or who have troublesome side effects. For those patients with symptoms of refractory OAB more invasive therapies including OnabotulinumtoxinA, sacral neuromodulation and Percutaneous Tibial Nerve Stimulation (PTNS) may be indicated. CONCLUSION We propose a new, evidence based, treatment algorithm for the management of OAB in patients who remain refractory to first line therapy.

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. In this review, we focus on recent advances in the management of OAB. We examine the evidence on the effect of anticholinergic load on OAB patients. Advances in medical treatment include a new beta-3 agonist, vibegron, which is thought to have fewer drug interactions than mirabegron. Treatment of genitourinary syndrome of the menopause with oestrogens and ospemifene have also shown promise for OAB. Botulinum toxin has been shown to be an effective treatment option. We discuss the new implantable neuromodulators that are on the market as well as selective bladder denervation and laser technology.

Abstract
Purpose of review To present the current literature on the pharmacologic management of overactive bladder, including combination therapies, agents still in clinical development, and special considerations related to individuals with cognitive decline, frailty and cardiovascular risk. Recent Findings Combination therapy is shown to be more effective than monotherapy, without additional side effects. Preliminary studies on novel treatment methods, including new medications, as well was novel use of established medications, demonstrates improved efficacy with a favorable side effect profile. Investigation into new target pathways may be an area for future pharmacologic development. Special consideration should be given when prescribing anti-muscarinic medication in the frail adult population. Overactive bladder has been associated with frailty and anti-muscarinic medications have been associated with the worsening cognitive decline. Summary Combination therapy is a safe and effective alternative to patients with refractory overactive bladder. Caution should be taken in prescribing medications for the frail older adult, and alternative first- and third-line treatments should be considered. Future studies should involve long term data on safety and outcomes stratified by age with objective measurements of cognition and frailty.

Abstract
CONTEXT Current literature suggests that several pathophysiological factors and mechanisms might be responsible for the nonspecific symptom complex of overactive bladder (OAB). OBJECTIVE To provide a comprehensive analysis of the potential pathophysiology underlying detrusor overactivity (DO) and OAB. EVIDENCE ACQUISITION A PubMed-based literature search was conducted in April 2018, to identify randomised controlled trials, prospective and retrospective series, animal model studies, and reviews. EVIDENCE SYNTHESIS OAB is a nonspecific storage symptom complex with poorly defined pathophysiology. OAB was historically thought to be caused by DO, which was either "myogenic" (urgency initiated from autonomous contraction of the detrusor muscle) or "neurogenic" (urgency signalled from the central nervous system, which initiates a detrusor contraction). Patients with OAB are often found to not have objective evidence of DO on urodynamic studies; therefore, alternative mechanisms for the development of OAB have been postulated. Increasing evidence on the role of urothelium/suburothelium and bladder afferent signalling arose in the early 2000s, emphasising an afferent "urotheliogenic" hypothesis, namely, that urgency is initiated from the urothelium/suburothelium. The urethra has also recently been regarded as a possible afferent origin of OAB-the "urethrogenic" hypothesis. Several other pathophysiological factors have been implicated, including metabolic syndrome, affective disorders, sex hormone deficiency, urinary microbiota, gastrointestinal functional disorders, and subclinical autonomic nervous system dysfunctions. These various possible mechanisms should be considered as contributing to diagnostic and treatment algorithms. CONCLUSIONS There is a temptation to label OAB as "idiopathic" without obvious causation, given the poorly understood nature of its pathophysiology. OAB should be seen as a complex, multifactorial symptom syndrome, resulting from multiple potential pathophysiological mechanisms. Identification of the underlying causes on an individual basis may lead to the definition of OAB phenotypes, paving the way for personalised medical care. PATIENT SUMMARY Overactive bladder (OAB) is a storage symptom syndrome with multiple possible causes. Identification of the mechanisms causing a patient to experience OAB symptoms may help tailor treatment to individual patients and improve outcomes.

Abstract
INTRODUCTION The pharmacological treatment of urinary incontinence and overactive bladder (OAB) has been, for a longer time, based on antimuscarinic agents. In recent years, two other pharmacological principles have been introduced for the treatment of OAB and urgency urinary incontinence: the β3-adrenergic agent mirabegron and botulinum neurotoxin. Meanwhile, there is lack of effective drugs for the treatment of stress incontinence. AREAS COVERED This literature review presents synthetic compounds aimed to treat female urinary incontinence that are in phase II-III clinical development. EXPERT OPINION Antimuscarinic agents will continue to represent the current gold standard for the first-line pharmacological management of OAB and urgency urinary incontinence. The class of β3-agonists will certainly expand with the discovery and clinical development of novel agents. Combination therapy of antimuscarinic agents and β3-agonists could offer an alternative treatment in these patients, including those with symptoms refractory to first-line monotherapy. A huge number of preclinical studies are underway in this field exploring the therapeutic potential of many novel compounds while some have advanced to clinical phases of development.

Abstract
PURPOSE OF REVIEW Post-prostatectomy overactive bladder (OAB) is a common and challenging condition to manage. The aim of the present report was to review the recent evidences regarding OAB symptoms that develop in men after prostatectomy and how to manage them. RECENT FINDINGS The prevalence of OAB after radical prostatectomy may range from 15.2 to 37.8%. Recent studies have highlighted the role of the urethrogenic mechanism (facilitation of the urethrovesical reflex due to stress urinary incontinence (SUI)) in the genesis of post-prostatectomy OAB in a significant proportion of patients. Several other pathophysiological factors such as iatrogenic decentralization of the bladder, defunctionalized bladder due to severe SUI, detrusor underactivity, or bladder outlet obstruction might be involved. The evaluation should aim to identify the underlying mechanism to tailor the treatment, which could range from SUI surgery, to fixing a urethral stricture, improving bladder emptying or using the conventional spectrum of OAB therapies. There is a paucity of data for OAB therapies specific to post-prostatectomy patients, with the exception of solifenacin, tolterodine, and botulinum toxin. There is currently no data on how preoperative management or surgical technique may prevent post-prostatectomy OAB.

Abstract
CONTEXT Pharmacological treatment is a cornerstone in the management of patients with lower urinary tract symptoms (LUTS). OBJECTIVE To review emerging evidence in the medical treatment of LUTS. EVIDENCE ACQUISITION An Embase/Pubmed-based literature search was conducted in December 2017, screening for randomized controlled trials (RCTs), prospective and retrospective series, animal model studies, and reviews on medical treatment of LUTS. EVIDENCE SYNTHESIS The main medical innovation in recent years in overactive bladder (OAB) has been the approval of the first β3-adrenoceptor agonists (mirabegron) and intradetrusor onabotulinum toxin A, while several other drugs such as antiepileptics, phosphodiesterase inhibitors, or other β3-agonists have brought promising results in phase 3 trials. Intraprostatic injections of various drugs for LUTS/benign prostatic hyperplasia have been investigated, but results of phase 3 trials are still pending, while combination therapies of phosphodiesterase type 5 inhibitors+α-blockers or finasteride have been proved as superior to single therapies in RCTs conducted in these patients. Two new formulations of desmopressin have been approved for nocturia in the USA (desmopressin nasal spray) and Europe/Canada/Australia (desmopressin orally disintegrated tablet). Fedovapagon, a vasopressin V2 receptor agonist, has recently completed a large phase 3 trial in male patients with nocturia. Other phase 3 trials are ongoing in bladder pain syndrome (AQX 11-25, a SHIP-1 activator) and in neurogenic detrusor overactivity (mirabegron and abobotulinum toxin A). CONCLUSIONS Medical treatment of LUTS is a very active research field with recently approved drugs for nocturia (desmopressin acetate nasal spray/orally disintegrated tablet) and numerous emerging drugs currently investigated in OAB, LUTS/benign prostatic hyperplasia, nocturia, bladder pain syndrome, and neurogenic detrusor overactivity. PATIENT SUMMARY Medical treatment of lower urinary tract symptoms is a very active research field with recently approved drugs for nocturia (desmopressin acetate nasal spray/orally disintegrated tablet) and numerous emerging drugs in overactive bladder, nocturia, neurogenic detrusor overactivity, bladder pain syndrome, or benign prostatic hyperplasia.

Abstract
INTRODUCTION Tadalafil is a promising phosphodiesterase (PDE) 5 inhibitor prescribed for erectile dysfunction (ED). Daily low dose (5 mg) of tadalafil has also been used for the treatment of male lower urinary tract symptoms (LUTS) associated with benign prostate hyperplasia (BPH). PDE5 inhibitors induce relaxation of smooth muscle cells in the urethra, prostate, bladder neck, and blood vessels. The aim of this study was to investigate the efficacy of tadalafil on vessels endothelial function, in patients with male LUTS symptoms associated with BPH. METHODS The Institutional Review Board (IRB) approved this clinical study and informed consents had been obtained from 81 BPH patients. The following male LUTS parameters: international prostate symptom score (IPSS), overactive bladder symptom score (OABSS), voiding volume, max and mean voiding flow on voiding flowmetry examination and post-voiding residual urine (RU) were compared at 0, 1, 3, 6, and 12 months after a daily dose of 5 mg tadalafil. In addition, erectile function was evaluated by the sexual health inventory for men (SHIM) score and vessels endothelial function and peripheral neuropathy were assessed by the brachial-ankle pulse wave velocity (baPWV), ankle brachial index (ABI), and vibration perception threshold (VPT) at 0, 3, 6, and 12 months after treatment. RESULTS The mean age of 81 patients was 66.4 ± 11.4 years old. Their prostate size was 30.2 ± 22.1 ml. Male LUTS parameters including IPSS, OABSS, and RU showed significant improvement from 1 to 12 months after tadalafil administration. Max and mean voiding flow was significantly increased at 6 months after tadalafil treatment. The SHIM score showed significant improvement after 3 months. Whilst, the results of baPWV also showed significant improvement from 3 to 12 months. ABI was also significantly improved at 6 months. However, there was no change in the VPT at any time point. CONCLUSIONS Tadalafil is effective for both male LUTS and ED. It is also shown that tadalafil improves baPWV, which we can conclude that higher vessels elasticity has been obtained. This major finding of this study shows that tadalafil has the potency to improve vessels endothelial dysfunction in patients with BPH.

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
The term OAB (overactive bladder) describes a symptom complex. Therefore, initial treatment should be based on clinical symptoms and the results of basic diagnostics. Patient preference is essential for the choice of the initial treatment. Behavioural therapy, electrostimulation and medical treatment are available treatment options. If these are not effective, extended diagnostic examinations should be performed prior to minimally invasive treatments, like onabotulinumtoxin injections in the detrusor or sacral neuromodulation. Surgical interventions like augmentation cystoplasty are rarely required today.
