Trilafon

Trilafon Uses, Dosage, Side Effects, Food Interaction and all others data.

An antipsychotic phenothiazine derivative with actions and uses similar to those of chlorpromazine.

Trilafon is a piperazinyl phenothiazine, acts on the central nervous system, and has a greater behavioral potency than other phenothiazine derivatives whose side chains do not contain a piperazine moiety. It is a member of a class of drugs called phenothiazines, which are dopamine D1/D2 receptor antagonists. Trilafon is 10 to 15 times as potent as chlorpromazine; that means perphenazine is a highly potent antipsychotic. In equivalent doses it has approximately the same frequency and severity of early and late extrapypramidal side-effects compared to Haloperidol.

Uses

Trilafon is a phenothiazine used to treat schizophrenia as well as nausea and vomiting.

For use in the management of the manifestations of psychotic disorders and for the control of severe nausea and vomiting in adults.

Trilafon is also used to associated treatment for these conditions: Anxiety, Depression, Schizophrenia, Moderate Agitation, Moderate Anxiety, Moderate Depressed mood, Severe Anxiety, Severe Depressed mood, Severe Nausea and vomiting, Severe agitation

How Trilafon works

Binds to the dopamine D1 and dopamine D2 receptors and inhibits their activity. The mechanism of the anti-emetic effect is due predominantly to blockage of the dopamine D2 neurotransmitter receptors in the chemoreceptor trigger zone and vomiting centre. Trilafon also binds the alpha andrenergic receptor. This receptor's action is mediated by association with G proteins that activate a phosphatidylinositol-calcium second messenger system.

Toxicity

Symptoms of overdose include stupor or coma, and children may have convulsive seizures. Signs of arousal may not occur for 48 hours. Oral LD₅₀=318 mg/kg (rat); IPR LD₅₀=64 mg/kg (mouse)

Food Interaction

• Avoid alcohol. Consuming alcohol may increase hypotension. Trilafon may increase the effects of alcohol.

Trilafon Alcohol interaction

[Moderate] GENERALLY AVOID:

Concurrent use of ethanol and phenothiazines may result in additive CNS depression and psychomotor impairment.

Also, ethanol may precipitate dystonic reactions in patients who are taking phenothiazines.

The two drugs probably act on different sites in the brain, although the exact mechanism of the interaction is not known.

Patients should be advised to avoid alcohol during phenothiazine therapy.
