1. Oxybutynin hydrochloride is an antimuscarinic agent prescribed to patients with an overactive bladder and symptoms of urinary urge incontinence. Oxybutynin undergoes pre-systemic metabolism, and the N-desethyloxybutynin (Oxy-DE), is reported to have similar anticholinergic effects. 2. We revisited the oxidative metabolic fate of oxybutynin by liquid chromatography tandem mass spectrometry analysis of incubations with rat and human liver fractions, and by measuring plasma and urine samples collected after oral administration of oxybutynin in rats...

A 57-year-old African American woman was being treated at our clinic for neurogenic urinary incontinence (UI). The UI, which occurred day and night, began 2 years earlier following a laminectomy of vertebrae C3 to C6 with spinal fusion of C3 to C7 for cervical spinal stenosis. The UI persisted despite physical therapy and trials of oxybutynin and imipramine. Since the surgery, the patient had also been experiencing chronic (debilitating) neuropathic pain in both legs, and the sensation of incomplete bladder emptying...

Hyperhidrosis is the excessive production of sweating, which can be primary and focal or secondary to various pathologies. The exact cause of primary focal hyperhidrosis is still unknown, although a genetic basis is recognized, and its prevalence varies from 1% to 2.8%. The most affected sites are the armpits, palms, soles and face. It causes much discomfort, affects the quality of life, and is estimated to be undervalued by health professionals. Many treatment options are proposed, both clinical and surgical...

AIMS: Overactive bladder (OAB) is highly prevalent particularly among obese patients and significantly impacts quality of life. Anticholinergics are the first-line treatment. The effect of obesity on medication compliance has not been studied. Our study evaluated gender- and obesity-specific adherence and persistence of anticholinergic medications in OAB. We also compared adherence and persistence on solifenacin to oxybutynin, tolterodine, and all anticholinergics combined. METHODS: Truven Marketscan Commercial Claims and Encounter database from 2005 to 2013 was used...

Hyperhidrosis, or abnormally increased sweating, is a condition that may have a primary or secondary cause. Usually medication- induced secondary hyperhidrosis manifests with generalized, rather than focal sweating. We report a 32-year-old woman with a history of palmoplantar hyperhidrosis for 15 years who presented for treatment and was prescribed oral glycopyrrolate. One month later, the palmoplantar hyperhidrosis had resolved, but she developed new persistent craniofacial sweating. After an unsuccessful trial of clonidine, oxybutynin resolved the craniofacial hyperhidrosis...

BACKGROUND: While muscarinic antagonists (anticholinergics) have shown efficacy in treating primary focal hyperhidrosis (PFH), side effects - most commonly dry mouth - are intolerable for most patients. THVD-102, a fixed-dose combination product has been developed combining oxybutynin, a muscarinic antagonist, and pilocarpine, a muscarinic agonist. The pilocarpine is at a dose level and release profile optimized to correct salivary flow impaired by oxybutynin yet not interfere with the therapeutic muscarinic antagonist effect of oxybutynin upon the sweat glands...

REVIEW
Sophie Ramsay, Stéphane Bolduc
Overactive bladder (OAB) is a highly prevalent disorder in the pediatric population. This condition is especially troublesome for pediatric patients and their families when associated with incontinence, since it negatively affects self-esteem and impairs children's development. From the patient's perspective, urgency and urge incontinence can have a significant impact, negatively affecting their quality of life. For a therapy to have true benefit, changes must not only be statistically significant, but must also be perceived as meaningful by the patient...

BACKGROUND: Overactive bladder syndrome (OAB) is a common medical condition that causes significant distress and impact on the quality of life in women. Muscarinic receptor antagonists remain the mainstay of therapy, but they are limited by their efficacy and adverse effects. The objective of the article was to compare the clinical efficacy and tolerability of medications used to treat OAB in women through network meta-analysis. METHODS: Data from eligible studies of commonly prescribed pharmacological agents in the treatment of OAB in women were entered into Net-MetaXL after a literature search using two online databases (PubMed and Cochrane)...
