Background:

Temiverine hydrochloride is a synthesized drug that is expected to have anticholinergic action.

Atropine (1 nM to 1 μM), Oxybutynin (10 nM to 10 μM), Temiverine (10 nM to 10 μM), and RCC-36 (10 nM to 1 μM) cause a parallel shift to the right of the concentration-response curves to acetylcholine stimulation[1].
