Background:
Mebeverine hydrochloride, a β-phenylethylamine derivative, is a musculotropic agent that potently blocks intestinal peristalsis. Mebeverine directly blocks voltage-operated sodium channels and inhibits intracellular calcium accumulation[1][2].
Mebeverine hydrochloride inhibits the α1 action by limiting the amount of available calcium mobilized on receptor stimulation of the smooth muscle cells of guinea-pig taenia caeci. Mebeverine (6×10-6 M) hydrochloride shows atropine-like properties by shifting to the right the concentration-response curve obtained with carbachol. The α1-receptor-induced hyperpolarization caused by adrenaline (3×10-6 M) in the presence of mebeverine declines after reaching an initial maximum. Mebeverine (6×10-5 M) hydrochloride causes a small hyperpolarization of the muscle cells (2.1 + 0.5 mV) and suppression of spike activity[2].
