We present a case of acute tolterodine overdose with anticholinergic toxidrome including drowsiness, confusion and pyrexia. Tolterodine was commonly used in recent years for the treatment of overactive bladder syndrome. Experience with acute tolterodine poisoning was limited. The pharmacology, clinical use and side effects of tolterodine were reviewed. The clinical manifestations, toxicology an...

Liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was used for simultaneous quantification of tolterodine and its metabolite 5-hydroxy methyl tolterodine in rat plasma. Tolterodine-d6 and 5-hydroxy methyl tolterodine-d14 were used as internal standards (IS). Chromatographic separation was performed on Ascentis Express RP amide (50 mm×4.6 mm, 2.7 μm) column with an isocratic mobil...

The purpose of the study was to develop a transdermal tolterodine tartrate (TT) patch and to analyse its efficacy for overactive bladder (OAB) treatment. Patches were prepared using various polymers and plasticizers via the solvent casting method. The patches were characterized for tensile strength, thickness, moisture content, modulus of elasticity and water absorption capacity. Differential s...

Tolterodine, a new muscarinic receptor antagonist, is metabolized via two pathways: oxidation of the 5-methyl group and dealkylation of the nitrogen. In an attempt to identify the specific cytochrome P450 enzymes involved in the metabolic pathway, tolterodine was incubated with microsomes from 10 different human liver samples where various cytochrome P450 activities had been rank ordered. Stron...

BACKGROUND Overactive bladder (OAB)/ storage lower urinary tract symptoms (LUTS) have a high prevalence affecting up to 90% of men over 80 years. The role of sufficient therapies appears crucial. In the present review, we analyzed the mechanism of action of tolterodine extended-release (ER) with the aim to clarify its efficacy and safety profile, as compared to other active treatments of OAB/st...
