| Description | Trimethobenzamide (Ro 2-9578 free base) is a D2 receptor antagonist and antiemetic agent, primarily utilized to mitigate nausea and vomiting by effectively blocking the D2 receptor. |
| In vitro | Trimethobenzamide, a (non-phenothiazine) benzamide antiemetic, centrally inhibits D2 receptors. This action blocks the medullary chemoreceptor trigger zone, preventing emetic impulses from reaching the vomiting center[1]. |
| In vivo | Trimethobenzamide exhibits an oral bioavailability ranging from 60% to 100%. Peak plasma concentrations are achieved approximately 45 minutes following oral administration, and approximately 30 minutes after intramuscular (I.M.) administration[1]. |
