Notes: Flavoxate-d5 is intended for use as an internal standard for the quantification of flavoxate (Item No. 19096) by GC- or LC-MS. Flavoxate is an inhibitor of L-type calcium channels and an antimuscarinic agent.{30978} It induces relaxation of potassium-precontracted isolated human urinary bladder detrusor muscle (IC50 = 2 µM) and reduces contractions induced by the acetylcholine receptor agonist carbachol (carbamoylcholine; Item No. 14486) or calcium in isolated rat detrusor strips.{30978,57774} Microinjection of flavoxate (0.68 µg/animal) into the oral pontine reticular nucleus inhibits reflex micturition in decerebrated cats, and intravenous or intracerebroventricular administration reduces isovolumetric rhythmic bladder contractions in rats.{57774} Formulations containing flavoxate have previously been used in the treatment of frequent or urgent urination, increased nocturnal urination, bladder pain, and urinary incontinence.
