Darifenacin is a potent, competitive and selective muscarinic receptor antagonist which has greater binding affinity for muscarinic M3 receptors. M3 receptors are involved in the contraction of the detrusor muscle of the bladder, GI smooth muscle, saliva production, and iris sphincter function. Darifenacin may increase volume threshold in patients with involuntary detrusor contraction, thus increase bladder capacity.
