Description
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.
Indication
For the treatment of postoperative nausea and vomiting and for nausea associated with gastroenteritis.
Pharmacology

Toxicity
Oral LD50 in mice is 1600 mg/kg.
Affected Organisms
Humans and other mammals
Biotransformation
Hepatic.
Absorption
The relative bioavailability of the capsule formulation compared to the solution is 100%.
Half Life
The mean elimination half-life of trimethobenzamide is 7 to 9 hours.
Elimination
Between 30 – 50% of a single dose in humans is excreted unchanged in the urine within 48–72 hours.
