Pharmacodynamics
Trimeprazine (also known as Alimemazine) is a tricyclic antihistamine, similar in structure to the phenothiazine antipsychotics, but differing in the ring-substitution and chain characteristics. Trimeprazine is in the same class of drugs as chlorpromazine (Thorazine) and trifluoperazine (Stelazine); however, unlike the other drugs in this class, trimeprazine is not used clinically as an anti-psychotic. It acts as an anti-histamine, a sedative, and an anti-emetic (anti-nausea). Trimeprazine is used principally as an anti-emetic, to prevent motion sickness or as an anti-histamine in combination with other medications in cough and cold preparations. Tricyclic antihistamines are also structurally-related to the tricyclic antidepressants, explaining the antihistaminergic adverse effects of these two drug classes and also the poor tolerability profile of tricyclic H<sub>1</sub>-antihistamines.
Mechanism of ActionTrimeprazine competes with free histamine for binding at HA-receptor sites. This antagonizes the effects of histamine on HA-receptors, leading to a reduction of the negative symptoms brought on by histamine HA-receptor binding.
