Trifluoperazine is one of the phenothiazine class of compounds and as such has many pharmacodynamic effects which relate to its therapeutic actions and side effects. The most notable action of phenothiazines is antagonism at dopamine receptors in the CNS. It is hypothesised that this action in the limbic system and associated areas of cerebral cortex is the basis of the antipsychotic action of phenothiazines, whilst in the medullary chemoreceptor trigger zone it appears to be responsible for the antiemetic effect of these agents.

Trifluoperazine is a piperazine phenothiazine tranquilliser with potent antipsychotic, anxiolytic and anti-emetic activity, and a pharmacological profile of moderate sedative and hypotensive properties, and fairly pronounced tendency to cause extrapyramidal reactions.
