BACKGROUND Constipation is a common side effect of antimuscarinic treatment for overactive bladder (OAB). This review evaluates the incidence and impact of constipation on the lives of patients with OAB being treated with darifenacin. METHODS Constipation data from published Phase III and Phase IIIb/IV darifenacin studies were reviewed and analyzed. Over 4000 patients with OAB (aged 18-89 yea...

Study selection Randomised or quasi-randomised controlled trials in adults with symptomatic diagnosis of overactive bladder syndrome, urodynamic diagnosis of detrusor overactivity, or both, that compared an anticholinergic drug (given to decrease symptoms of overactive bladder) with placebo or no treatment. Studies of darifenacin, emepronium bromide or carrageenate, dicyclomine chloride, oxybut...

BACKGROUND Antimuscarinic agents are the most popular treatment for overactive bladder and their efficacy in man is well documented, producing decreased urinary frequency and an increase in bladder capacity. During cystometry in rats, however, the main effect reported after acute treatment with antimuscarinics is a decrease in peak micturition pressure together with little or no effect on bladd...

The metabolic activation of the prohormone vitamin D(3) requires a 25-hydroxylation that has been reported to be catalyzed by both mitochondrial CYP27A and a microsomal vitamin D(3) 25-hydroxylase in the liver. CYP27A has been extensively studied, but its role as a physiologically important vitamin D(3) 25-hydroxylase has been questioned. The present paper reports that the microsomal vitamin D(...

A simple, selective, precise and stability-indicating high-performance liquid chromatographic (HPLC) method of analysis tolterodine tartrate in pharmaceutical dosage form was developed and validated. The chromatographic conditions comprised a reversed-phase C18 column (250 × 4.6 mm), 5 μ with a mobile phase consisting of a mixture of buffer solution (2.88 g ammonium dihydrogen orthophosphate in...
