Abstract
bladder based on a systematic review and network meta-analysis approach. METHODS Pubmed, Embase, Web of Science, and the Cochrane Register of Clinical Trials databases were systematically searched. The search time frame was from database creation to June 2, 2022. Randomized controlled double-blind trials of oral medication for overactive bladder were screened against the protocol's entry criteria. Trials were evaluated for quality using the Cochrane Risk of Bias Assessment Tool, and data were statistically analyzed using Stata 16.0 software. RESULT A total of 60 randomized controlled double-blind clinical trials were included involving 50,333 subjects. Solifenacin 10mg was the most effective in mean daily micturitions and incontinence episodes, solifenacin 5/10mg in mean daily urinary urgency episodes and nocturia episodes, fesoterodine 8mg in urgency incontinence episodes/d and oxybutynin 5mg in voided volume/micturition. In terms of safety, solifenacin 5mg, ER-tolterodine 4mg, mirabegron, vibegron and ER-oxybutynin 10mg all showed a better incidence of dry mouth, fesoterodine 4mg, ER-oxybutynin 10mg, tolterodine 2mg, and vibegron in the incidence of constipation. Compared to placebo, imidafenacin 0.1mg showed a significantly increased incidence in hypertension, solifenacin 10mg in urinary tract infection, fesoterodine 4/8mg and darifenacin 15mg in headache. CONCLUSION Solifenacin showed better efficacy. For safety, most anticholinergic drugs were more likely to cause dry mouth and constipation, lower doses were better tolerated. The choice of drugs should be tailored to the patient's specific situation to find the best balance between efficacy and safety.

Oral Surg Oral Med Oral Pathol Oral Radiol 2023:S2212-4403(23)00068-8. [PMID: 37198047 DOI: 10.1016/j.oooo.2023.01.012] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 12/11/2022] [Accepted: 01/25/2023] [Indexed: 03/08/2023]
Abstract
OBJECTIVE The purpose of this study was to identify all outcome domains used in clinical studies of xerostomia, that is, subjective sensation of dry mouth. This study is part of the extended project "World Workshop on Oral Medicine Outcomes Initiative for the Direction of Research" to develop a core outcome set for dry mouth. STUDY DESIGN A systematic review was performed on MEDLINE, EMBASE, CINAHL, and Cochrane Central Register of Controlled Trials databases. All clinical and observational studies that assessed xerostomia in human participants from 2001 to 2021 were included. Information on outcome domains was extracted and mapped to the Core Outcome Measures in Effectiveness Trials taxonomy. Corresponding outcome measures were summarized. RESULTS From a total of 34,922 records retrieved, 688 articles involving 122,151 persons with xerostomia were included. There were 16 unique outcome domains and 166 outcome measures extracted. None of these domains or measures were consistently used across all the studies. The severity of xerostomia and physical functioning were the 2 most frequently assessed domains. CONCLUSION There is considerable heterogeneity in outcome domains and measures reported in clinical studies of xerostomia. This highlights the need for harmonization of dry mouth assessment to enhance comparability across studies and facilitate the synthesis of robust evidence for managing patients with xerostomia.

Adverse Events Associated with Nonsurgical Treatments for Urinary Incontinence in Women: a Systematic Review. J Gen Intern Med 2019; 34:1615-1625. [PMID: 31062225 PMCID: PMC6667523 DOI: 10.1007/s11606-019-05028-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/22/2019] [Revised: 02/06/2019] [Accepted: 03/28/2019] [Indexed: 10/26/2022]
Abstract
BACKGROUND Urinary incontinence (UI) is a common malady in women. Numerous nonsurgical treatments are available, each associated with risk of adverse events (AEs). METHODS We systematically reviewed nonsurgical interventions for urgency, stress, or mixed UI in women, focusing on AEs. We searched MEDLINE®, Cochrane Central Trials Registry, Cochrane Database of Systematic Reviews, and Embase® through December 4, 2017. We included comparative studies and single-group studies with at least 50 women. Abstracts were screened independently in duplicate. One researcher extracted study characteristics and results with verification by another independent researcher. When at least four studies of a given intervention reported the same AE, we conducted random effects model meta-analyses of proportions. We also assessed the strength of evidence. RESULTS There is low strength of evidence that AEs are rare with behavioral therapies and neuromodulation, and that periurethral bulking agents may result in erosion and increase the risk of voiding dysfunction. High strength of evidence finds that anticholinergics and alpha agonists are associated with high rates of dry mouth and constitutional effects such as fatigue and gastrointestinal complaints. Onabotulinum toxin A (BTX) is also associated with increased risk of urinary tract infections (UTIs) and voiding dysfunction (moderate strength of evidence). DISCUSSION Behavioral therapies and neuromodulation have low risk of AEs. Anticholinergics and alpha agonists have high rates of dry mouth and constitutional effects. BTX is associated with UTIs and voiding dysfunction. Periurethral bulking agents are associated with erosion and voiding dysfunction. These AEs should be considered when selecting appropriate UI treatment options. AE reporting is inconsistent and AE rates across studies tended to vary widely. Trials should report AEs more consistently.

Abstract
Tolterodine is metabolized to an active 5-hydroxymethyl tolterodine (5-HMT) by CYP2D6. This study investigated the relationship between CYP2D6 genotypes and pharmacokinetics of tolterodine and its active metabolite in healthy Korean subjects. All volunteers were genotyped for CYP2D6 and divided into four different genotype groups (CYP2D6*wt/*wt [*wt = *1 or *2], CYP2D6*wt/*10, CYP2D6*10/*10, and CYP2D6*5/*10). Each subject received a single oral dose of tolterodine tartrate (2 mg) in single-dose phase of the study. After the single-dose phase of the study, the same subjects received a single oral dose of tolterodine tartrate (2 mg) once daily for 1 week during multiple-dose tolterodine administration phase. Plasma concentrations of tolterodine and 5-HMT were measured by using liquid chromatography-tandem mass spectrometry method. Our study demonstrated that plasma exposure of tolterodine in CYP2D6*10/*10 and CYP2D6*5/*10 group significantly increased, compared with CYP2D6*wt/*wt group (P < 0.001). The pharmacokinetic parameters of 5-HMT were not significantly different in relation to CYP2D6 genotype, as 5-HMT itself is also metabolized by CYP2D6. With regard to active moiety (tolterodine + 5-HMT), Cmax and AUC0-24 was significantly increased in CYP2D6*10/*10 group, compared with CYP2D6*wt/*wt group (P < 0.001). Thus, our study showed the pharmacokinetics of tolterodine and its active moiety was significantly different in relation to CYP2D6 genotype.

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.

[PMID: 27955902 DOI: 10.1016/j.purol.2016.10.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2015] [Revised: 10/20/2016] [Accepted: 10/21/2016] [Indexed: 11/26/2022]
Abstract
INTRODUCTION Mouth and eye dryness are frequently reported by patients with multiple sclerosis (MS) as side effects of antimuscarinic drugs used for neurogenic overactive bladder. We evaluated the impact of antimuscarinic drugs prescription on these symptoms. METHODS MS patients consulting for overactive bladder were included. Xerostomia were evaluated at baseline and thirty days after treatment by self-reporting questionnaires (Xerostomia Quality of Life [X-Qol] and Xerostomia Questionnaire [XQ]), by salivary flow rate and sugar test. Xerophtalmia were evaluated by a self-reporting questionnaire (Ocular Surface Disease Index [OSDI]) and Schirmer test. Iatrogenic anticholinergic impregnation was evaluated by the Anticholinergic Drug Scale. RESULTS From January to December 2014, 35 patients were included. Mean age was 50.1±10.2 years, mean EDSS=4.9. Mean anticholinergic impregnation was 0.6±1.0. Before treatment, none correlation was found between anticholinergic impregnation and other parameters. Twenty-two patients were evaluated after treatment. At baseline and thirty days after treatment, mean scores were respectively: 0.78±0.51 and 0.73±0.43 (P=0.67) for X-Qol, 9.22±11.8 and 7.03±11.4 (P=0.32) for XQ, 18.8±14.9 and 13.9±11.6 (P=0.06) for OSDI. Mean salivary flow rates were respectively 1.54±1.11 and 1.22±1.3 (P=0.53), positive sugar tests concerned respectively 68% and 55% of patients (P=0.53), and positive Schirmer test concerned 50% before and after treatment. CONCLUSION Eye and mouth dryness exist in our MS population, even before prescription of antimuscarinic treatment, and is not getting worse after prescription. Those symptoms should not be the reason to stop an efficient treatment, but should be the reason to find and treat their aetiology. LEVEL OF EVIDENCE 4.

Abstract
Overactive bladder (OAB) is a common and chronic condition that impacts patients' daily activities and quality of life. Pharmaco-therapy for OAB is a mainstay of treatment. Antimuscarinics and β3-adrenoceptor agonists are the two major classes of oral pharmacotherapy and have similar efficacy for treating the symptoms of OAB. Owing to the chronic nature of OAB, long-term use of medication is essential for OAB symptom control and positive health outcomes. However, many patients elect to stop their medications during the treatment period. Unmet expectations of treatment and side effects seem to be the major factors for discontinuing OAB pharmacotherapy. Furthermore, the short- and long-term persistence and compliance with medication management are markedly worse in OAB than in other chronic medical conditions. Improvement in persistence and compliance with OAB pharmacotherapy is a hot topic in OAB treatment and should be an important goal in the treatment of OAB. Effective strategies should be identified to improve persistence and compliance. In this review, we outline what is known about persistence and compliance and the factors affecting persistence with pharmacotherapy in patients with OAB.

Abstract
BACKGROUND Around 16% to 45% of adults have overactive bladder symptoms (urgency with frequency and/or urge incontinence - 'overactive bladder syndrome'). Anticholinergic drugs are common treatments. OBJECTIVES To compare the effects of different anticholinergic drugs for overactive bladder symptoms. SEARCH METHODS We searched the Cochrane Incontinence Group Specialised Trials Register (searched 8 March 2011) and reference lists of relevant articles. SELECTION CRITERIA Randomised trials in adults with overactive bladder symptoms or detrusor overactivity that compared one anticholinergic drug with another, or two doses of the same drug. DATA COLLECTION AND ANALYSIS Two authors independently assessed eligibility, trial quality and extracted data. Data were processed as described in the Cochrane Reviewers' Handbook. MAIN RESULTS Eighty six trials, 70 parallel and 16 cross-over designs were included (31,249 adults). Most trials were described as double-blind, but were variable in other aspects of quality. Crossover studies did not present data in a way that could be included in the meta-analyses. Twenty nine collected quality of life data (the primary outcome measure) using validated measures, but only fifteen reported useable data.Tolterodine versus oxybutynin: There were no statistically significant differences for quality of life, patient reported cure or improvement, leakage episodes or voids in 24 hours, but fewer withdrawals due to adverse events with tolterodine (Risk Ratio (RR) 0.52, 95% confidence interval (CI) 0.40 to 0.66, data from eight trials), and less risk of dry mouth (RR 0.65, 95% CI 0.60 to 0.71, data from ten trials).Solifenacin versus tolterodine: There were statistically significant differences for quality of life (standardised mean difference (SMD) -0.12, 95% CI -0.23 to -0.01, data from three trials), patient reported cure/improvement (RR 1.25, 95% CI 1.13 to 1.39, data from two trials), leakage episodes in 24 hours (weighted mean difference (WMD) -0.30, 95% CI -0.53 to -0.08, data from four studies) and urgency episodes in 24 hours (WMD -0.43, 95% CI -0.74 to -0.13, data from four trials), all favouring solifenacin. There was no difference in withdrawals due to adverse events and dry mouth, but after sensitivity analysis the dry mouth (RR 0.69, 95% CI 0.51 to 0.94) was statistically significantly lower with solifenacin when compared to Immediate Release (IR) tolterodine.Fesoterodine versus extended release tolterodine: Three trials contributed to the meta analyses. There were statistically significant differences for quality of life (SMD -0.20, 95% CI -0.27 to -0.14), patient reported cure/improvement (RR 1.11, 95% CI 1.06 to 1.16), leakage episodes (WMD -0.19, 95% CI -0.30 to -0.09), frequency (WMD -0.27, 95% CI -0.47 to -0.06) and urgency episodes (WMD -0.44, 95% CI -0.72 to -0.16) in 24 hours, all favouring fesoterodine, but those taking fesoterodine had higher risk of withdrawal due to adverse events (RR 1.45, 95% CI 1.07 to 1.98) and higher risk of dry mouth (RR 1.80, 95% CI 1.58 to 2.05) at 12 weeks.Different doses of tolterodine: The standard recommended starting dose (2 mg twice daily) was compared with two lower (0.5 mg and 1 mg twice daily), and one higher dose (4 mg twice daily). The effects of 1 mg, 2 mg and 4 mg doses were similar for leakage episodes and micturitions in 24 hours, with greater risk of dry mouth with 2 and 4 mg doses at two to 12 weeks.Different doses of solifenacin: The standard recommended starting dose of 5 mg once daily was compared to 10 mg: while frequency and urgency were less (better) with 10 mg compared to 5 mg, there was a higher risk of dry mouth with 10 mg solifenacin at four to 12 weeks.Different doses of fesoterodine:The recommended starting dose of 4mg once daily was compared to 8 and 12 mg. The clinical efficacy (patient reported cure, leakage episodes, micturition per 24 hours) of 8 mg was better than 4 mg fesoterodine but with a higher risk of dry mouth with 8 mg.There was no statistically significant difference between 4 and 12 mg in the efficacy but the dry mouth was significantly higher with 12 mg at eight to 12 weeks.Extended versus immediate release preparations of oxybutynin and/or tolterodine: There were no statistically significant differences for cure/improvement, leakage episodes or micturitions in 24 hours, or withdrawals due to adverse events, but there were few data. Overall, extended release preparations had less risk of dry mouth at two to 12 weeks.One extended release preparation versus another: There was less risk of dry mouth with oral extended release tolterodine than oxybutynin (RR 0.75, 95% CI 0.59 to 0.95), but no difference between transdermal oxybutynin and oral extended release tolterodine although some people withdrew due to skin reaction at the transdermal patch site at 12 weeks. AUTHORS' CONCLUSIONS Where the prescribing choice is between oral immediate release oxybutynin or tolterodine, tolterodine might be preferred for reduced risk of dry mouth. With tolterodine, 2 mg twice daily is the usual starting dose, but a 1 mg twice daily dose might be equally effective, with less risk of dry mouth. If extended release preparations of oxybutynin or tolterodine are available, these might be preferred to immediate release preparations because there is less risk of dry mouth.Between solifenacin and immediate release tolterodine, solifenacin might be preferred for better efficacy and less risk of dry mouth. Solifenacin 5 mg once daily is the usual starting dose, this could be increased to 10 mg once daily for better efficacy but with increased risk of dry mouth.Between fesoterodine and extended release tolterodine, fesoterodine might be preferred for superior efficacy but has higher risk of withdrawal due to adverse events and higher risk of dry mouth.There is little or no evidence available about quality of life, costs, or long-term outcome in these studies. There were insufficient data from trials of other anticholinergic drugs to draw any conclusions.

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
1. The effectiveness of antimuscarinic agents in the treatment of the overactive bladder (OAB) syndrome is thought to arise through blockade of bladder muscarinic receptors located on detrusor smooth muscle cells, as well as on nondetrusor structures. 2. Muscarinic M3 receptors are primarily responsible for detrusor contraction. Limited evidence exists to suggest that M2 receptors may have a role in mediating indirect contractions and/or inhibition of detrusor relaxation. In addition, there is evidence that muscarinic receptors located in the urothelium/suburothelium and on afferent nerves may contribute to the pathophysiology of OAB. Blockade of these receptors may also contribute to the clinical efficacy of antimuscarinic agents. 3. Although the role of muscarinic receptors in the bladder, other than M3 receptors, remains unclear, their role in other body systems is becoming increasingly well established, with emerging evidence supporting a wide range of diverse functions. Blockade of these functions by muscarinic receptor antagonists can lead to similarly diverse adverse effects associated with antimuscarinic treatment, with the range of effects observed varying according to the different receptor subtypes affected. 4. This review explores the evolving understanding of muscarinic receptor functions throughout the body, with particular focus on the bladder, gastrointestinal tract, eye, heart, brain and salivary glands, and the implications for drugs used to treat OAB. The key factors that might determine the ideal antimuscarinic drug for treatment of OAB are also discussed. Further research is needed to show whether the M3 selective receptor antagonists have any advantage over less selective drugs, in leading to fewer adverse events.
