Date of preparation: 6111 Royalmount Avenue, Suite 102 May 21, 2009 Montreal, Quebec H4P 2T4 Control No.: 130078 Page _ _ 2 PRESCRIBING INFORMATION PR DUVOID ® (bethanechol chloride) 10, 25 AND 50 MG TABLETS, USP PARASYMPATHOMIMETIC ACTIONS AND CLINICAL PHARMACOLOGY Bethanechol acts principally by producing the effects of stimulation of the parasympathetic nervous system. It increases the tone of the detrusor urinae muscle, usually producing a contraction sufficiently strong to initiate micturition and empty the bladder. It stimulates gastric motility, increases gastric tone, and often restores rhythmic peristalsis. Stimulation of the parasympathetic nervous system releases acetylcholine at the nerve endings. When spontaneous stimulation is reduced and therapeutic intervention is required, acetylcholine can be given, but it is rapidly hydrolyzed by cholinesterase, and its effects are transient. Bethanechol is not destroyed by cholinesterase and its effects are more prolonged and predictable than those of acetylcholine. It has predominant muscarinic action and only feeble nicotinic action. Doses that stimulate micturition and defecation and increase peristalsis do not ordinarily stimulate ganglia or voluntary muscles. Therapeutic test doses in normal human subjects have little effect on heart rate, blood pressure, or peripheral circulation. INDICATIONS AND CLINICAL USE The treatment of acute postoperative and postpartum nonobstructive (functional) urinary retention and for neurogenic atony of the urinary bladder with retention.
