Action against Disease Model Trospium Trospi uM chloride is a quaternary ammoni uM compound, which is a competitive antagonist at muscarinic cholinergic receptors. Preclinical studies using porcine and h uMan detrusor muscle strips demonstrated that trospi uM chloride was many-fold more potent than oxybutynin and tolterodine in inhibiting contractile responses to carbachol and electrical stimulation. The drug ispoorly bioavailable orally (< 10%) and food reduces absorption by 70%- 80%. It is predominantly eliminated renally as unchanged compound. Trospi uM chloride, dosed 20 mg twice daily, is significantlysuperior to placebo in improving cystometric parameters, reducing urinary frequency, reducing incontinence episodes, and increasing urine vol uMe per micturition. In active-controlled trials, trospi uM chloride was at least equivalent to immediate-release formulations of oxybutynin and tolterodine in efficacy and tolerability. The most problematic adverse effects of trospi uM chloride are the anticholinergic effects of dry mouth and constipation. Comparative efficacy/tolerability data with long-acting formulations of oxybutynin and tolterodine as well as other anticholinergics such as solifenacin and darifenacin are not available. On the basis of available data, trospi uM chloride does not appear to be a substantial advance upon existing anticholinergics in the management of urge urinary incontinence. [552802] Drug Info
