(Minor) Beverages containing caffeine may aggravate bladder symptoms and counteract the effectiveness of tolterodine to some degree. Absorption : TOLTERODINE is rapidly absorbed. Mechanism Of Action. The dose may be lowered to 2 mg daily based on individual response and tolerability. Mechanism of Action of Tolterodine Tartarate Tolterodine tartrate is a specific muscarinic receptor (M3 receptor) antagonist. Tolterodine shows a preference for the urinary bladder receptors in animal models over the salivary receptors. Mechanism of action of Tolterodine (Detrol): It is a competitor antagonist to muscarinic receptors. By blocking the effect of acetylcholine on the muscle cells, tolterodine slows the build-up of pressure in the bladder, reduces the sensation to urinate, and prevents uncontrolled urination. Tolterodine exhibits a high specificity for muscarinic receptors. Prolongation of the gastrointestinal transit time may be the mechanism of the constipating effect. Both tolterodine and the 5-hydroxymethyl metabolite exhibit a high specificity for muscarinic receptors, since both show negligible activity or affinity for other neurotransmitter receptors and other potential cellular targets, such as calcium channels. Tolterodine has a pronounced effect on bladder function. acetylcholine … Competitive muscarinic receptor antagonist; decreases bladder contractions; is more specific for bladder than oxybutynin. 8.1 Pharmacology. Tolterodine has a pronounced effect on bladder function. The main effects of tolterodine are an increase in residual urine, reflecting an incomplete emptying of the bladder, and a decrease in detrusor pressure, consistent with an antimuscarinic action on the lower urinary tract. Tolterodine. it blocks muscarinic receptors which can be found on the muscle cells of the bladder wall. Its mechanism of action includes enhanced neurotransmission of GABA (by inhibiting GABA transaminase, which breaks down GABA).
