[3-(2-Chloro-phenothiazin-10-yl)-propyl]-dimethyl-ammonium

UsesChlorpromazine hydrochloride is used in the treatment of schizophrenia; anti-emetic; as an antipsychotic in pills, injections, and suppositories; to relieve nausea and vomiting associated with malignant diseases. In veterinary medicine, it is used as an anti-emetic, tranquilizer and sedative. It has slight antihistaminic and anti adrenaline actions. It is a peripheral vasodilator and adepressant that blocks dopamine receptors in the central nervous system.

General DescriptionChlorpromazinehydrochloride, 2-chloro-10-[3-(dimethylamino)propyl]phenothiazine monohydrochloride (Thorazine), was the first phenothiazinecompound introduced into therapy. It is still usefulas an antipsychotic. Other uses are in nausea, vomiting, andhiccough. Oral doses of chlorpromazine and thioridazinehave systemic availability of 25% to 35% because of significantfirst-pass metabolism. Chlorpromazine and other phenothiazinesare metabolized extensively by CYP2D6. In contrast, bioavailability of chlorpromazine may beincreased up to 10-fold with injections, but the clinical doseusually is decreased by only threefold to fourfold.Chlorpromazine may weakly induce its own hepatic metabolism,because its concentration in blood is lower after severalweeks of treatment at the same dosage. Alterations of GImotility also may contribute. The drug has significant sedativeand hypotensive properties, possibly reflecting centralhistaminergic and peripheral α1-noradrenergic blockingactivity, respectively. Effects of peripheral anticholinergic activityare common. As with the other phenothiazines, the effectsof other CNS-depressant drugs, such as sedatives andanesthetics, can be potentiated.
