What is "telenzepine"

n. An antimuscarinic used in the treatment of peptic ulcers.

Telenzepine is a thienobenzodiazepine acting as selective M antimuscarinic. It is used in the treatment of peptic ulcers. Telenzepine is atropisomeric, in other words the molecule has a stereogenic C–N-axis; in neutral aqueous solution it displays a half-life for racemization of the order of 1000 years. The enantiomers have been resolved. The activity is related to the -isomer which is about 500-fold more active as the -isomer at muscarinic receptors in the rat cerebal cortex.
