Mastop Pharmacology

Trimethobenzamide is a novel antiemetic which prevents nausea and vomiting in humans. Its actions are unclear but most likely involves the chemoreceptor trigger zone (CTZ). In dogs pretreated with trimethobenzamide HCl, the emetic response to apomorphine is inhibited, while little or no protection is afforded against emesis induced by intragastric copper sulfate.

Mastop Absorption

The relative bioavailability of the capsule formulation compared to the solution is 100%.

Mastop side effects and Toxicity
