Jiang YH, Kuo HC. Current optimal pharmacologic therapies for overactive bladder. Expert Opin Pharmacother 2023; 24:2005-2019. [PMID: 37752121 DOI: 10.1080/14656566.2023.2264183] [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: 08/16/2023] [Accepted: 09/25/2023] [Indexed: 09/28/2023]
Abstract
INTRODUCTION Overactive bladder (OAB) is a common syndrome in adults. Current pharmacologic treatment includes antimuscarinic agents and β-3 adrenoceptor agonists. For non-responders to oral medication, intravesical injection of botulinum toxin A (BoNT-A) is an effective option. However, these treatments have potential adverse events and should be cautiously selected for appropriate patients. This review presents the recently published results of clinical trials and studies for patients with OAB and the underlying pathophysiology of OAB. Appropriate medical therapy based on pathophysiology of OAB is also presented. AREAS COVERED Literature search from Pubmed from 2001 to 2023 including clinical background, pharmacology, and clinical studies for OAB medications. EXPERT OPINION Treatment of OAB syndrome with any antimuscarinic or β-3 adrenoceptor agonist is feasible as a first-line approach. For patients with suboptimal therapeutic effect to full-dose antimuscarinics or mirabegron, combination with both drugs can improve efficacy. Intravesical BoNT-A 100-U injection provides therapeutic effects for refractory OAB. Patients who are refractory to initial pharmacotherapies should be investigated for the underlying pathophysiology; then an appropriate medication can be added, such as an α1-blocker or anti-inflammatory agents. Patient education about behavioral modification and therapies should always be provided with oral medication or BoNT-A injection for OAB patients.

Overview of current pharmacotherapeutic options in benign prostatic hyperplasia. Expert Opin Pharmacother 2023; 24:1609-1622. [PMID: 37448198 DOI: 10.1080/14656566.2023.2237406] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Revised: 06/27/2023] [Accepted: 07/13/2023] [Indexed: 07/15/2023]
Abstract
INTRODUCTION Benign prostatic hyperplasia (BPH) represents the histological entity of prostate cell proliferation, which inflicts a gradually increasing obstruction of the bladder outlet and is accompanied by a progressing manifestation of lower urinary tract symptoms (LUTS). BPH management algorithm includes conservative measures, pharmaceutical agents, and surgical procedures. AREAS COVERED A comprehensive literature review was performed using PubMed, Scopus, and Google Scholar databases to identify publications written in English, analyzing BPH pharmaceutical treatment. The search was conducted from January 2000 to January 2023. Six main drug classes can be administered, either as monotherapy or in combination. Furthermore, the authors provide current direction of research on future medications, which focuses on a more etiological interference to the BPH pathophysiological mechanism. EXPERT OPINION The available medications represent an effective first-line step of BPH/LUTS therapy. Currently, the administration of BPH medications is tailored to patient/disease characteristics and entails long-time adherence to therapy. The emergence of new surgical modalities, which combine significantly lower morbidity compared to standard procedures and more durable effects than the available medications, seems to challenge the current treatment algorithm. More direct comparisons and the increasing experience with these surgical modalities will delineate the switch points between various therapy levels along the BPH management sequence.

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
Male lower urinary tract symptoms (LUTSs) are highly prevalent in men and the incidence increases with aging. The pathophysiology of male LUTSs might be bladder outlet dysfunctions such as bladder neck (BN) dysfunction, benign prostatic obstruction, and poor relaxation of external sphincter and bladder dysfunctions such as detrusor overactivity (DO), detrusor underactivity, DO, and inadequate contractility. Male LUTSs include voiding and storage symptoms, and precision diagnosis should not be done based on the symptoms alone. Videourodynamic study provides a thorough look at the bladder and bladder outlet and can clearly demonstrate the underlying pathophysiology when the initial medication fails to relieve LUTS. Medical treatment should be given based on the underlying pathophysiology of LUTS, and surgical intervention to remove prostate should only be performed when a definite bladder outlet obstruction due to prostatic obstruction has been confirmed by invasive urodynamic study.

Abstract
Overactive bladder (OAB) syndrome is highly prevalent in both men and women and might have negative impact on quality of life. Clinical trials of OAB usually highly select participants that may not reflect the real-world practice of OAB patients. The spectrum of OAB includes patients with idiopathic, neuropathic, with bladder outlet obstruction, and patients in elderly and medical comorbidities. Patients might have poor response to OAB medication or have adverse events after treatment. Therefore, treatment of OAB should be individualized to obtain therapeutic efficacy and avoid unacceptable adverse events. This article reviews the recently published literature and provides a guide for physicians to choose the appropriate treatment for different OAB patients.

Abstract
Besides the mainstay of α-blockers and 5α-reductase inhibitors, other forms of medical therapy complete the armamentarium in the treatment of lower urinary tract symptoms (LUTS) in men. These treatments can target specific symptoms as well as associated symptoms that would affect the quality of life of the patients. Many patients are bothered by storage symptoms, more so than the voiding symptoms. Antimuscarinics are efficacious and safe, provided the patients do not have high post void residual urine. Many patients with LUTS also have erectile dysfunction, and phosphodiesterase type V inhibitors are effective in relieving both LUTS as well as erectile dysfunction for such patients. Phytotherapy provides a popular and safe treatment for LUTS, however, the efficacy of the treatment has not been proven in well conducted prospective randomized controlled studies.

Abstract
Background: The medium-to-long-term use of antimuscarinics alone or in combination with an α-blocker in men with an enlarged prostate is still controversial. This double-blind, placebo-controlled, randomized clinical trial aimed to investigate the efficacy and safety of medium-to-long-term use of tolterodine extended release (ER) with or without tamsulosin in patients with benign prostate hyperplasia (BPH) and larger prostate size. Methods: Totally, 152 patients (age ≥50 years) with BPH, International Prostate Symptom Score (IPSS) ≥12, quality-of-life (QoL) score ≥3, and total prostate volume ≥25 ml were enrolled in this study. The patients were randomized into four groups (n = 38 in each) to receive tolterodine ER placebo plus tamsulosin placebo, 0.2 mg tamsulosin plus tolterodine ER placebo, 4 mg tolterodine ER plus tamsulosin placebo, or tolterodine ER plus tamsulosin once daily for 24 weeks. IPSS (total, storage, and voiding subscales), QoL, maximum urinary flow rate (Qmax), and postvoid residual volume (PVR) were collected at baseline, and at weeks 4, 12, and 24. Results: Compared with placebo, tolterodine ER plus tamsulosin significantly improved total IPSS (−7.15, −12.20, and −14.66 vs. −3.51, −5.78, and −7.23), storage IPSS (−3.56, −5.63, and −6.66 vs. −1.52, −1.21, and −2.43), voiding IPSS (−2.88, −5.10, and −6.48 vs. −1.52, −3.03, and −2.97), QoL (−1.21, −2.40, and −3.21 vs. −0.39, −1.41, and −1.60), Qmax (2.21, 7.97, and 9.72 ml/s vs. 2.15, 2.44, and 2.73 ml/s), and PVR (−17.88, −26.97, and −27.89 ml vs. −12.03, −11.16, and −16.73 ml) at weeks 4, 12, and 24, respectively; the differences were all statistically significant (P < 0.05). Adverse events (AEs) were not increased with treatment progression. Tolterodine ER alone did not improve total IPSS (−4.61, −6.79, and −5.70), voiding IPSS (−0.64, −1.83, and −1.45), QoL (−0.69, −1.21, and −1.41), or Qmax (−0.79, 2.83, and 1.11 ml/s), compared with placebo (all P > 0.05). However, a gradual increase in PVR (10.03, 10.41, and 12.89 ml) and more urinary AEs suggestive of urinary retention (11/38 vs. 4/38) were observed. Conclusion: Medium-to-long-term use of tolterodine ER plus tamsulosin should be recommended in patients with BPH and an enlarged prostate volume.

Abstract
As men age, there is an increased incidence of lower urinary tract symptoms (LUTS), often from benign prostatic hyperplasia (BPH) which can adversely affect sexual function. There are many different treatments for these symptoms; however, many of the treatments also affect sexual quality of life, specifically in the realm of ejaculation. Our paper will review the medications, surgical procedures, minimally invasive procedures, and even investigational procedures used to treat LUTS/BPH and the effect they have on ejaculation. The aim of this paper is to help practitioners counsel patients more effectively on treatment options when ejaculation is a concern.

Abstract
Mirabegron, which was the first β3-adrenoceptor agonist introduced for use in clinical practice, has been extensively evaluated in overactive bladder (OAB) patients in several phase II and III studies. However, most of the enrolled patients were treatment naive or had experienced a wash-out period before the introduction of mirabegron. No study has reported the treatment results of a direct switch from antimuscarinics to mirabegron, which may more commonly occur in clinical practice. This is an observational study to assess the therapeutic efficacy and safety of directly switching from antimuscarinics to mirabegron in patients with OAB receiving stable antimuscarinic treatment. Moreover, we sought to identify the patients who benefited more from the change.Patients aged ≥20 years with OAB receiving stable antimuscarinics for >3 months were enrolled. Antimuscarinics were discontinued in all patients and mirabegron 25 mg, once daily was initiated. Primary end-point was global response assessment (GRA) at 1 month after medication switching. Baseline parameters and parameters changed 1 month after medication switching were compared between patients with GRA ≥ 1 and GRA < 1.Of the 282 enrolled patients (209 men, 73 women; mean age, 74.4 years), 55.3% had better (GRA ≥ 1), 31.2% had similar (GRA = 0), and 10.3% had worse (GRA < 0) outcomes. The overall adverse events (AE) rate decreased from 24.1% to 12.8%. In overall patients, there was no significant improvement of OAB symptoms, but postvoid residual (PVR) urine decreased and voiding symptoms and quality of life index improved significantly. Patients with GRA ≥ 1 had significantly improved both storage and voiding symptoms. A total of 195 patients (69.1%) can maintain mirabegron without adding or resuming antimuscarinics for more than 3 months. Logistic regression analysis indicated that higher baseline OAB symptoms scores were predictor of satisfactory outcome.More than 50% patients exhibited better outcomes after switching from antimuscarinics to mirabegron. Significantly lower AE rates and decreased PVR were noted. Higher baseline OAB symptom scores may predict a better outcome.

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.

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
AIMS To compare the therapeutic effects and identify predictors of successful treatment of first-line antimuscarinic and α-blocker monotherapy for men with predominant storage lower urinary tract symptoms (LUTS). METHODS This prospective randomised comparative study included men aged ≥ 40 years with a total IPSS ≥ 8, IPSS storage subscore (IPSS-S) ≥ voiding subscore (IPSS-V) and PVR ≤ 250 ml. Subjects were randomised to receive tolterodine 4 mg or doxazosin 4 mg daily for 12 weeks. The primary end-point included changes of total IPSS, IPSS subscore and global response assessment (GRA) after treatment. The secondary end-points included comparisons of baseline parameters between patients with a GRA ≥ 1 and GRA < 1. All adverse events were also recorded. RESULTS This study was completed by 163 patients. The IPSS-T, IPSS-S and quality of life index decreased significantly in both groups. An improved outcome (GRA ≥ 1) at 4 weeks was reported in 51/74 patients (68.9%) receiving doxazosin and 69/89 patients (77.5%) receiving tolterodine. The rate of improved outcome in patients with a TPV < 40 ml was significantly higher in tolterodine group (73.3% vs. 57.6%, p = 0.040). Patients with tolterodine treatment failure (GRA < 1) had higher baseline IPSS-V and IPSS intermittency domain, whereas patients with doxazosin treatment failure had a higher baseline IPSS urgency domain. CONCLUSIONS The rate of improved outcome was comparable between first-line tolterodine and doxazosin monotherapy for male storage LUTS. Antimuscarinic monotherapy was suggested for men with smaller prostate volume and higher urgency symptom scores, whereas α-blocker monotherapy was suggested for those with higher voiding symptom scores.
