Tolterodine is a potent and competitive muscarinic receptor antagonist, which has been shown to inhibit carbachol-induced contraction of isolated bladder preparations from rats, guinea pigs, and man. Tolterodine L-tartrate (henceforth referred to as tolterodine) inhibits contractions of the detrusor muscle from the guinea pig, and electrically induced contractions of human detrusor muscle from stable and overactive bladders ex vivo. Tolterodine is significantly more potent in inhibiting acetylcholine-induced urinary bladder contractions than electrically induced salivation in the anesthetized cat. It is highly specific for muscarinic receptors and has a very weak affinity for a-adrenoreceptors, histamine receptors, neuromuscular junction, and calcium channels.
