Phenothiazine drugs
Pharmacology
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.

Do not use trifluoperazine in control of nausea and vomiting occurring either prior to myelography or postprocedure with metrizamide. Pregnancy.
Overdose Effects
Signs and symptoms will be predominantly extrapyramidal; hypotension may occur. Treatment consists of gastric lavage together with supportive and symptomatic measures. Do not induce vomiting. Extra pyramidal symptoms may be treated with an anticholinergic, antiparkinsonism drug. Treat hypotension with fluid replacement; if severe or persistent. nor adrenaline may be considered. Adrenaline is contraindicated.
