Abstract
Objective Only a few numbers of studies have been published on the use of abobotulinumtoxinA (Dysport®) in idiopathic detrusor overactivity (IDO). This study reported the long-term follow-up of women with IDO who were treated with intravesical Dysport® injections. Methods Two hundred and thirty-six patients with IDO who had failed first-line conservative and antimuscarinic therapy received 500-900 units of Dysport® between April 2014 and July 2015. All patients were followed up for 5 years after their initial injection and interviewed on the phone. Results A total of 236 women with IDO aged from 18 years to 84 years (mean±standard deviation: 49.6±15.9 years) were included in our study. The median follow-up time for patients was 36.5 (range: 10-70) months, and the median recovery time after injection was 18.5 (range: 0-70) months. A total of 83 (35.2%) patients stated that they had subjective improvement of their symptoms whereas 84 (35.6%) patients did not report any improvement in symptoms. The initial International Consultation on Incontinence Questionnaire Overactive Bladder mean score was 6.9 (standard deviation 3.4). There was a positive association between the median recovery time and the components of the International Consultation on Incontinence Questionnaire Overactive Bladder questionnaire. Conclusion In a sub-population of overactive bladder patients with IDO who have failed first-line therapy, a single intravesical Dysport® injection can resolve patient symptoms completely or reduce the symptoms to an acceptable level that can be controlled with antimuscarinics or re-injection on demands.

Trigonal-Sparing vs. Trigonal-Involved OnabotulinumtoxinA Injection for the Treatment of Overactive Bladder: A Systematic Review and Meta-Analysis. Front Neurol 2021; 12:651635. [PMID: 34690904 PMCID: PMC8531119 DOI: 10.3389/fneur.2021.651635] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2021] [Accepted: 09/06/2021] [Indexed: 11/13/2022] Open
Abstract
Objective: Overactive bladder (OAB) is a disease characterized by the presence of urinary urgency. We carried out a meta-analysis to assess the effectiveness and safety of trigonal-involved injection of onabotulinumtoxinA (BoNT-A) in comparison with the trigonal-sparing technique in cases with OAB [neurogenic detrusor overactivity (NDO) and idiopathic detrusor overactivity (IDO)]. Methods: Randomized controlled trials (RCTs) of BoNT-A injection for OAB were searched systematically by using EMBASE, MEDLINE, and the Cochrane Controlled Trials Register. The datum was calculated by RevMan version 5.3.0. The original references of relating articles were also reviewed. Results: In total, six RCTs involving 437 patients were included in our analysis. For OAB, the trigone-including group showed a different patient symptom score (p = 0.03), complete dryness rate (p = 0.002), frequency of incontinence episodes (p = 0.01), detrusor pressure at maximum flow rate (p = 0.01), and volume at the first desire to void (p = 0.0004) compared with the trigone-sparing group. Also, a trigone-including intradetrusor injection demonstrated a significant improvement in the patient symptom score (p = 0.0004), complete dryness rate (p = 0.0002), frequency of incontinence episodes (p = 0.0003), detrusor pressure at maximum flow rate (p = 0.01), and volume at the first desire to void (p = 0.00006) compared with the trigone-sparing group for treatment of NDO. The adverse events rates were similar in both groups. Conclusions: The meta-analysis has demonstrated that trigone-including BoNT-A injection was more effective compared with the trigone-sparing injection for the treatment of OAB, especially for NDO.

Abstract
A considerable number of patients arriving in dental offices are being treated with ongoing medication for a variety of chronic diseases. As a result, dentists must be familiar with the potential side effects these therapeutic agents may have on the tissues of the oral cavity, and in particular on the salivary gland. Salivary gland function may be altered by a wide range of medications, leading to effects such as xerostomia, hyposalivation, hypersalivation or even swelling of the glands. These disorders can cause a variety of other health complications. This review will focus on the most common groups of drugs responsible for salivary gland dysfunction, including psychoactive drugs, antidepressants, antipsychotics, antihypertensives, and antihistamines.

Abstract
Background: Urinary incontinence (UI) is a common and refractory complication for patients with neurogenic detrusor overactivity (NDO) or idiopathic overactive bladder (IOAB). Objectives: To evaluate the effect of Botulinum toxin A (BTX-A) based on different dosages strategy for UI. Method: The MEDLINE, Ovid EMbase, The Cochrane Central Register of Controlled Trials (CENTRAL), China National Knowledge Internet (CNKI), and WanFang database were searched for relevant published randomized controlled trials (RCTs) between 1969 to September 31, 2018. All database were searched to identify relevant randomized controlled trials (RCTs) that investigated the clinical benefit of BTX-A for management of UI in patients with NDO and IOAB. Results: This meta-analysis involved 19 original studies. The BTX-A was superior to placebo in reducing episodes of UI for NDO patients in all subgroups of different dosages for different durations, and also reduced maximum detrusor pressure in all kinds of 200U and 300U at 6 weeks. However, it increased post void residual in different dosages of 200U at 2 weeks. For IOAB patients, compared to placebo, BTX-A increased detrusor compliance for different dosages of 200U and 300U at 12 and 36 weeks, but it increased risk of urinary tract infections at other dosages. Conclusions: This meta-analysis indicated that BTX-A 200U and 300U are more effective than placebo in the treatment of NDO, with minimal, local, and manageable adverse events. Furthermore, BTX-A 300U and 200U could also improve detrusor compliance of IOAB. However, more RCTs would still be necessary to explore the effect of BTX-A on management of UI in NDO and IOAB patients.

Abstract
We describe the case of a 49-year-old male who presented to the emergency department with right-sided weakness and inability to speak. He was diagnosed with stroke and was admitted to Qatar Rehabilitation Institute after he was treated for the acute phase at Hamad General Hospital. As part of his management, he was started on oxybutynin 5 mg orally twice daily for the treatment of overactive bladder. Within a week, his liver enzymes started to increase. After a thorough medication review, oxybutynin was suspended as it was the only suspected medication to be responsible of this elevation in liver enzymes. When Naranjo Adverse Drug Reaction Probability Scale was used to assess the probability of an adverse drug reaction (ADR), a score of 6 was obtained indicating a “Probable” ADR. In conclusion, this is the first published report of oxybutynin-induced elevation in liver enzymes. Further reports are required to highlight this probable ADR and alert all health professionals about it.

Evaluating the effect of three newly approved overactive bladder syndrome treating agents on parotid and submandibular salivary glands: Modulation of CXCL10 expression. Acta Histochem 2018; 120:269-281. [PMID: 29496263 DOI: 10.1016/j.acthis.2018.02.008] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2017] [Revised: 01/01/2018] [Accepted: 02/20/2018] [Indexed: 02/08/2023]
Abstract
BACKGROUND Despite enormous progresses in understanding pathophysiology of the lower urinary tract, antimuscarinics remain the chief clinically well-established approach for improving symptoms of overactive bladder (OAB). Dry mouth on the other hand remains one of the most untolerated systemic side effects of these drugs that limits their uses and results in high discontinuation rate. Three novel drugs have been recently approved by US Food and Drug Administration for treatment of OAB: trospium, darifenacin, and solifenacin. AIMS This study has been conducted to provide clear head to head comparative studying of histological and ultrastructural effect of those newly emerging drugs on parotid and submandibular salivary glands and to demonstrate the differential expression of CXCL10 to make a cogent structural and molecular assessment of the relative tolerability of these drugs and the potential mechanisms of occurrence of dry mouth. METHODS Fifty male Sprague Dawley rats were equally divided into five groups: Group I (control), Group II (oxybutynin-treated), Group III (trospium-treated), Group IV (darifenacin-treated) and Group V (solifenacin-treated). Histological and ultrastructural studies were performed on parotid and submandibular glands. Measurement of salivary flow, PCR analysis and immunohistochemical assessment of CXCL10 expression have been carried-out. RESULTS Muscarinic receptor antagonists led to various histological, morphometric and ultrastructural changes together with diminished salivary secretion and up-regulation of CXCL10 expression with the mildest alterations observed with solifenacin. CONCLUSIONS Solifenacin has shown the least adverse effects to salivary glands. CXCL10 is involved in degenerative changes of salivary glands induced by muscarinic antagonists.

Abstract
Purpose To assess the effectiveness and safety of botulinum toxin A (BTX-A) at different dosages for overactive bladder (OAB). Materials and Methods The MEDLINE, EMBASE, and Cochrane Controlled Trials Register databases were searched through November 3, 2016 to identify relevant randomized controlled trials (RCTs). Results Eleven studies were identified in this meta-analysis. Compared with placebo, the urinary incontinence (UI) episodes per week as the primary outcomes, urodynamic parameters including maximum cystometric capacity (MCC), and maximum detrusor pressure (MDP) for neurogenic detrusor overactivity (NDO) at 6 weeks, and for idiopathic detrusor overactivity (IDO) at 36 weeks were evaluated. These and other outcomes for effectiveness of BTX-A at different dosages in two observation periods indicate that a dose greater than 50 U is significantly more effective for certain symptoms of OAB compared with placebo. However, there were no significant differences between some dosages. Compared with placebo, the outcomes of total adverse events for NDO and for IDO show that doses of 300 U and 200 U for NDO are associated with more complications. Conclusions In consideration that the treatments of BTX-A were with minimal, local, and manageable adverse effects, this meta-analysis demonstrates that BTX-A 200 U is recommended for management of NDO for short-term treatment for there was no significant difference from the larger dose of 300U. The short-term efficacies of BTX-A for IDO remain to be investigated.

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
Overactive bladder (OAB) increases with age. OAB in the elderly may be associated with increased risks of falls, fractures and mortality. Degeneration of the central nervous system in the elderly is proposed as one of the pathogenic factors for OAB. Recently, onabotulinumtoxinA (BoNT-A) 100 U has been demonstrated to be well tolerated, and it significantly improves all OAB symptoms and health-related quality of life in patients who are inadequately managed with anticholinergics. However, an increased risk of a large post-void residual volume and a lower long-term success rate were noted in frail elderly patients. Careful patient selection for BoNT-A injection treatment is important in elderly OAB patients. Patients who are frail, are elderly, have comorbidity or have a post-void residual volume >100 mL should be monitored carefully after BoNT-A injection treatment to prevent urinary retention and subsequent urinary tract infection. Use of liposomes to carry BoNT-A across the urothelial barrier decreases urgency-frequency episodes without compromising detrusor contractility and might avoid urinary tract infection. This treatment might prevent undesired detrusor underactivity after BoNT-A injection treatment, especially in elderly patients who have low detrusor contractility. For treatment of OAB in the elderly, clinicians should be aware of the balance between therapeutic efficacy and safety.

Abstract
Background: OnabotulinumtoxinA is widely used in treating neurogenic detrusor overactivity (NDO). We carried out a systematic review and meta-analysis to assess the efficacy and safety of the drug for treating NDO. Methods: We searched the following databases: Medline, EMBASE, and the Cochrane Controlled Trials Register. All published randomized double-blind, placebo-controlled trials of onabotulinumtoxinA for the treatment of NDO were identified in the analysis. The reference lists of the retrieved studies were also investigated. Results: Four publications involving a total of 807 patients were identified in the analysis, which compared onabotulinumtoxinA with placebo. The changes of the mean number of urinary incontinence per week (the standardized mean difference [SMD] = −10.91, 95% confidence intervals [CIs] = −14.18–−7.63, P < 0.0001); maximum cystometric capacity (SMD = 146.09, 95% CI = 126.19–165.99, P < 0.0001) and maximum detrusor pressure (SMD = −32.65, 95% CI = −37.83–−27.48, P < 0.0001) indicated that onabotulinumtoxinA was more effective than the placebo, despite the doses of onabotulinumtoxinA. Safety assessments primarily localized to the urinary tract indicated onabotulinumtoxinA were often associated with more complications. Urinary tract infections (relative risk [RR] =1.48, 95% CI = 1.20–1.81, P = 0.0002); hematuria (RR = 1.81, 95% CI = 1.00–3.24, P = 0.05) and urinary retention (RR = 5.87, 95% CI = 3.61–9.56, P < 0.0001). Conclusions: This meta-analysis indicates that onabotulinumtoxinA to be an effective treatment for NDO with side effects primarily localized to urinary tract.

Abstract
INTRODUCTION Overactive bladder (OAB) is a term used to describe the symptom syndrome of urgency, with or without urgency incontinence, usually associated with frequency and nocturia. Antimuscarinics are the most widely prescribed class of drugs for OAB, although their systemic adverse effects limit their use in clinical practice as compliance. This has led to developments in the field. AREAS COVERED In this review, the authors describe Phase II drugs that target cholinergic receptors. First, the authors present the new antimuscarinics (tarafenacin and afacifenacin). This is followed by reports on a combination drug (tolenix) containing a muscarinic antagonist (tolterodine) associated with a muscarinic agonist (pilocarpine). Further, the authors discuss the trials of well-known drugs in either new combination therapy (solifenacin and mirabegron) or with new routes of delivery (oxybutynin vaginal ring). Finally, the authors examine the option of targeting nicotinic acetylcholine receptors (dexmecamylamine). EXPERT OPINION Different strategies have been adopted to improve the efficacy and tolerability of therapeutics for OAB. Nicotinic receptors represent a novel therapeutic target; however, it is unlikely that antimuscarinic agents will be replaced as standard first-line therapy in the near future.

Abstract
AIM We carried out a systematic review and meta-analysis to assess the efficacy and safety of the drug for treating idiopathic OAB. METHODS A literature review was performed to identify all published randomized double-blind, placebo-controlled trials of onabotulinumtoxinA for the treatment of idiopathic OAB. The search included the following databases: MEDLINE, EMBASE, and the Cochrane Controlled Trials Register. The reference lists of the retrieved studies were also investigated. RESULTS Eight publications involving a total of 1,320 patients were used in the analysis, including six RCTs that compared onabotulinumtoxinA with placebo. OnabotulinumtoxinA significantly decreased the mean number of urinary incontinence (UI) per day -2.77 versus -1.01 (the standardized mean difference (SMD) = -1.68, 95% CI = -2.06 to -1.31, P < 0.00001); the mean number of micturitions per day -1.61 versus -0.87 (SMD = -1.82, 95% CI = -2.61 to -1.02, P < 0.00001); maximum cystometric capacity (MCC) 91.39 versus 32.32 (SMD = 63.82, 95% CI = 38.14 to 89.50, P < 0.00001) and volume voided 44.29 versus 7.36 (SMD = 33.05, 95% CI = 22.45 to 43.66, P < 0.00001) versus placebo and 29.20% versus 7.95% of patients became incontinence-free (odds ratio [OR] = 4.89, 95% confidence interval [CI] = 3.11 to 7.70, P < 0.00001). Safety assessments primarily localized to the urinary tract indicated onabotulinumtoxinA were often associated with complications resulting from postvoid residuals (PVR; P < 0.00001), urinary tract infections (UTI; P < 0.00001) and clean intermittent catheterization (CIC; P < 0.00001). CONCLUSION This meta-analysis indicates that onabotulinumtoxinA to be an effective treatment for idiopathic overactive bladder symptoms with side effects primarily localized to urinary tract.

Abstract
PURPOSE Mirabegron, a potent and selective β3-adrenoceptor agonist, has been developed for the treatment of overactive bladder (OAB). We carried out a systematic review and meta-analysis to assess the efficacy and safety of the drug for treating OAB. METHODS A literature review was performed to identify all published randomized double-blind, placebo-controlled phase III trials of mirabegron for the treatment of OAB. The search included the following databases: MEDLINE, EMBASE and the Cochrane Controlled Trials Register. The reference lists of the retrieved studies were also investigated. A systematic review and meta-analysis of phase III trials were conducted. RESULTS Four publications involving a total of 5,761 patients were used in the analysis, including four phase III RCTs that compared mirabegron with placebo. We found that mirabegron was effective in treating OAB in our meta-analysis. Co-primary efficacy end points: the mean number of incontinence episodes per 24 h (the standardized mean difference (SMD) = -0.44, 95 % confidence interval (CI) -0.59 to -0.29, p < 0.00001); the mean number of micturitions per 24 h (SMD = -0.62, 95 % CI -0.80 to -0.45, p < 0.00001) and key secondary efficacy end points: mean volume voided per micturition; mean number of urgency episodes per 24 h indicated that mirabegron was more effective than the placebo. Safety assessments included common treatment-emergent adverse events (TEAEs) [OR 1.10, 95 % CI 0.93-1.31, p = 0.25), hypertension, cardiac arrhythmia TEAEs, urinary retention and discontinuations due to adverse event indicated that mirabegron was well tolerated. CONCLUSIONS This meta-analysis indicates that mirabegron to be an effective and safe treatment for OAB symptoms with a low occurrence of side effects. It offers promise as an effective oral agent for the treatment of OAB with a distinct efficacy/tolerability balance.

Abstract
PURPOSE Many patients with overactive bladder discontinue pharmacotherapy due to suboptimal efficacy or side effects. Mirabegron, a β3-adrenoceptor agonist, may offer an effective and well tolerated alternative treatment for overactive bladder. MATERIALS AND METHODS A randomized, double-blind, placebo controlled trial was conducted in the United States and Canada. After a 2-week placebo run-in period, adults with overactive bladder symptoms for 3 or more months were randomized 1:1:1 to receive placebo, 50 or 100 mg mirabegron once daily for 12 weeks. Efficacy data were collected via patient completed diaries and quality of life assessments. Co-primary efficacy end points were changes from baseline to final visit in mean number of incontinence episodes per 24 hours and micturitions per 24 hours. Key secondary micturition and incontinence end points were also evaluated. Safety assessments included treatment emergent adverse events, laboratory assessments, vital signs, electrocardiograms and post-void residual volume. RESULTS Compared to placebo, 50 and 100 mg mirabegron groups demonstrated statistically significantly greater mean decreases (95% CI) from baseline for incontinence episodes (-1.13 [-1.35, -0.91], -1.47 [-1.69, -1.25] and -1.63 [-1.86, -1.40]) and micturitions (-1.05 [-1.31, -0.79], -1.66 [-1.92, -1.40] and -1.75 [-2.01, -1.48]) per 24 hours (p <0.05). Significant improvements in all key secondary end points were observed for both mirabegron doses vs placebo. The incidence of frequently reported treatment emergent adverse events (hypertension, urinary tract infection, headache, nasopharyngitis) was similar in the mirabegron and placebo groups. Dry mouth was reported for 1.5%, 0.5% and 2.1% of patients in the placebo, 50 and 100 mg mirabegron groups, respectively. CONCLUSIONS Once daily mirabegron in a 50 or 100 mg dose is an effective treatment for overactive bladder symptoms with a low occurrence of side effects.

Abstract
Overactive bladder (OAB) is a chronic distressing condition characterised by urinary urgency with or without urge incontinence, usually with frequency (voiding at least eight times daily) and nocturia. It affects millions of people worldwide independent of age, sex and race. The prevalence increases with age and is relatively higher in women compared with men. The treatment of OAB is aimed at reducing the debilitating symptoms so as to improve the overall quality of life for patients. Anticholinergic agents targeting the muscarinic receptors in the bladder represent the mainstay of pharmacotherapy for the treatment of OAB. Besides their status as the current standard of care, use of antimuscarinic drugs is limited by certain side effects, particularly dry mouth and constipation; therefore, various attempts have been made to improve the organ selectivity of these drugs to overcome the side effects. These include the development of new antimuscarinic agents with structural modifications and the use of innovative drug delivery methods. The advancement in the drug delivery systems extends to the long-term therapeutic efficacy with improved tolerability and patient compliance; however, future prospective therapies are aimed at novel targets with novel mechanisms of action, including beta3-adrenoceptor agonists, K+ channel openers, 5-HT modulators and botulinum toxin, which are currently under different stages of clinical development. Among other investigational therapies, neurokinin receptor antagonists, alpha-adrenoceptor antagonists, nerve growth factor inhibitors, gene therapy and stem cell-based therapies are of considerable interest. The future for the development of new modalities for the treatment of OAB looks promising.

Abstract
Overactive bladder (OAB) affects millions of individuals and may severely impair the quality of life of those affected. The contribution of human behavior to manifestations of this symptom complex remains poorly understood. Continued evolution of our understanding of the pathophysiology of OAB has identified contributory mechanisms, which in turn may open new therapeutic avenues. Recent improvements in drug delivery systems represent advances in the management of OAB. However, more complete symptom control with greater tolerability is desirable; this awaits the development of agents specific for newly emerging and as yet unidentified pathophysiologic pathways. Importantly, as understanding of outcomes assessment in OAB matures, refined assessments of disease severity, response to intervention, and patient preference should be possible.

Abstract
Treatment of HIV infection with highly active antiretroviral therapy (HAART) requires sustained adherence to treatment to maintain efficacy. In pediatric patients, adherence to HAART represents a significant challenge for treated children and for their caregivers and healthcare providers. Many factors can affect adherence to HAART including: (i) factors related to the patient and his/her family; (ii) factors related to the drug/medication; and (iii) factors related to the healthcare system. Different strategies can be employed to tackle the specific obstacles identified in these three groups, and thus to facilitate adherence. Among the key interventions centered on the patient and his/her family are the tailoring of the HAART regimen to the daily activities of the child and his/her family, and the implementation of an intensive education program on adherence for the child and the caregiver, prior to starting the treatment. Specific medication-related problems (depending on drug pharmacokinetic and pharmacodynamic properties, taste and palatability, food interactions, etc.) exist; such problems can not be solved solely by clinicians or by families. Greater commitment of the pharmaceutical industry is needed, and innovative solutions have to be identified by clinicians in partnership with drug manufacturers. Furthermore, the development of an 'adherence strategy/program' can be recommended to all institutions working in pediatric HIV infection. Most of the necessary interventions to be included in such programs can be easily implemented, but they require trained and committed staff (and institutions), and time to be spent with patients and their caregivers.

Abstract
PURPOSE We assessed the effect of darifenacin, an M3 selective receptor antagonist, on the warning time associated with urinary urgency. MATERIALS AND METHODS In this multicenter, double-blind study subjects with urinary urgency for 6 months or greater and episodes of urgency 4 times or greater daily were randomized to darifenacin controlled release tablets (30 mg once daily) or placebo. Warning time was defined as the time from the first sensation of urgency to voluntary micturition or incontinence. Data were collected using electronic event recorders during 6-hour clinic visits or 3 urge-void cycles, if shorter, at baseline and at treatment end. RESULTS A total of 72 subjects entered the study and 67 were included in the primary efficacy analysis (darifenacin in 32 and placebo in 35). Darifenacin treatment resulted in a significant increase in mean warning time with a median increase of 4.3 minutes compared with placebo (p = 0.003). Overall 47% of darifenacin treated subjects compared with 20% receiving placebo achieved a 30% increase or greater in mean warning time (OR 5.6, p = 0.009). Median and minimum warning times were also significantly increased following darifenacin treatment vs placebo (p = 0.004 and 0.017, respectively). The median difference in minimum warning time was 1.9 minutes in favor of darifenacin vs placebo. CONCLUSIONS To our knowledge this is the first study to evaluate change in warning time, which is potentially important to individuals with symptoms associated with overactive bladder. Darifenacin increases mean, median and minimum warning time compared with placebo, allowing subjects more time to reach a toilet and potentially avoiding the embarrassing experience of incontinence.

Abstract
OBJECTIVE To report a case of Carbamazepine toxicity following the administration of Oxybutynin and Dantrolene. STUDY DESIGN A case report. SETTING The Spinal Rehabilitation Department, Loewenstein Hospital, Raanana, Israel. METHODS A patient with C6D tetraplegia who sustained intoxication because of drug interaction is presented. She had been treated by Carbamazepine 1000 mg/day for neuropathic pain for 2 years without clinical or laboratory signs of toxicity. After administration of Oxybutynin concomitantly with an increase in the dose of Dantrolene, she presented the clinical symptoms and laboratory finding of Carbamazepine intoxication. Trying to adjust the treatment to the patient's requirements, Carbamazepine together with Oxybutynin and Dantrolene was readministrated in lower doses. RESULTS The combination of these drugs, even small doses, caused toxicity. Adding Dantrolene and Oxybutynin elevated the blood level of Carbamazepine, possibly by inhibition of cytochrome P450. CONCLUSION A possible pharmacokinetic interaction between Dantrolene and Oxybutynin should be borne in mind when considering Carbamazepine medication for a patient with a spinal cord lesion.

Abstract
PURPOSE In this phase 3 trial we assessed the efficacy of solifenacin 5 mg and 10 mg daily in patients with symptoms related to overactive bladder. In addition, we assessed the safety and acceptability of solifenacin. MATERIALS AND METHODS The study was a multicenter, multinational, randomized, double-blind, placebo controlled trial. Patients were randomized to 12-week once daily treatment with solifenacin 5 mg, solifenacin 10 mg or placebo. The primary efficacy variable was changed from baseline to study end point in mean number of micturitions per 24 hours. Secondary efficacy variables included changes from baseline in mean number of urgency, nocturia and incontinence episodes per 24 hours, and mean volume voided per micturition. RESULTS Compared with changes obtained with placebo (-1.59), micturitions per 24 hours were statistically significantly decreased with solifenacin 5 mg (-2.37, p = 0.0018) and solifenacin 10 mg (-2.81, p = 0.0001). A statistically significant decrease was observed in the number of incontinence episodes with both solifenacin doses (5 mg, p = 0.002 and 10 mg, p = 0.016). This effect was also seen for episodes of urge incontinence (5 mg, p = 0.014 and 10 mg, p = 0.042). Of patients reporting incontinence at baseline, fully 50% achieved continence after treatment with solifenacin. Episodes of nocturia were statistically significantly decreased in patients treated with solifenacin 10 mg (-0.71, -38.5%) versus placebo (-0.52, -16.4%, p = 0.036). Episodes of urgency were statistically significantly reduced with solifenacin 5 mg (-2.84, -51%, p = 0.003) and solifenacin 10 mg (-2.90, -52%, p = 0.002). Mean volume voided per micturition was statistically significantly increased with both solifenacin doses (p = 0.0001). Treatment with solifenacin was well tolerated. Dry mouth, mostly mild in severity, was reported in 7.7% of patients receiving solifenacin 5 mg and 23% receiving solifenacin 10 mg (vs 2.3% with placebo). CONCLUSIONS In this study treatment with solifenacin 5 mg and 10 mg once daily significantly improved all the major symptoms of overactive bladder including frequency, urgency and incontinence. Solifenacin 10 mg also decreased the frequency of nocturia. Solifenacin therapy was associated with a favorable tolerability profile and a low incidence of dry mouth, especially at the 5 mg starting dose.

Abstract
OBJECTIVE To identify drugs associated with the complaint of dry mouth. MATERIALS AND METHODS MEDLINE was searched for papers 1980-2002 using keywords, oral, mouth, salivary, drugs, dry mouth and xerostomia, and relevant secondary references were hand-searched. RESULTS Evidence was forthcoming for a number of xerogenic drugs, especially antimuscarinic agents, some sympathomimetic agents, and agents affecting serotonin and noradrenaline uptake, as well as a miscellany of other drugs such as appetite suppressants, protease inhibitors and cytokines. CONCLUSION Dry mouth has a variety of possible causes but drugs--especially those with anticholinergic activity against the M3 muscarinic receptor--are the most common cause of reduced salivation.
