ClassificationTherapeutic: urinary tract antispasmodics
Overactive bladder with symptoms of urge urinary incontinence, urgency and urinary frequency.
Antagonizes the effect of acetylcholine at muscarinic receptors in the bladder; this parasympatholytic action reduces bladder smooth muscle tone.
Increased bladder capacity and decreased symptoms of overactive bladder.
Absorption: Less than 10% absorbed following oral administration; food significantly ↓ absorption.
Distribution: Mostly distributed to plasma.
Metabolism and Excretion: Of the 10% absorbed, 40% is metabolized. Unabsorbed drug is mainly excreted in feces. Of absorbed drug, 60% is eliminated in urine as unchanged drug via active tubular secretion.
Half-life: 20 hr.
