Chemical Properties

White Crystalline Powder


Antidyskinetic; antipsychotic


ChEBI: A compound composed of a central piperidine structure with hydroxy and p-chlorophenyl substituents at position 4 and an N-linked p-fluorobutyrophenone moiety.

brand name

Haldol (OrthoMcNeil).

General Description

Haloperidol, 4-[4-(p-chlorophenyl)-4-hydroxypiperidino]-4-fluorobutyrophenone (Haldol), is anodorless white to yellow crystalline powder. Haloperidol iswell and rapidly absorbed and has a high bioavailability. It ismore than 90% bound to plasma proteins. Haloperidol is excretedslowly in the urine and feces. About 30% of a dose isexcreted in urine and about 20% of a dose in feces via biliaryelimination,and only 1% of a dose is excreted as unchangeddrug in the urine.Haloperidol is a minor substrate of CYP1A2 and a major substrate of CYP2D6 and CYP3A4.CYP2D6 inhibitors may increase the levels/effects ofhaloperidol.Haloperidol may increase the levels/effects ofCYP2D6 substrates and it may decrease the bioactivationof CYP2D6 prodrugs substrates. Haloperidol also is a moderateinhibitor of CYP2D6 and CYP3A4. CYP3A4 inducersmay decrease the levels/effects of haloperidol, whereasCYP3A4 inhibitors may increase the levels/effects ofhaloperidol. Centrally acting acetylcholinesterase inhibitorsmay increase the risk of antipsychotic-related EPS. The precisemechanism of antipsychotic action is unclear but isconsidered to be associated with the potent DA D2receptor–blocking activity in the mesolimbic system and theresulting adaptive changes in the brain. Haloperidol is usedprimarily for the long-term treatment of psychosis and is especiallyuseful in patients who are noncompliant with theirdrug treatment.

General Description

Haloperidol, 4[4-(p-chlorophenyl)-4-hydroxypiperidone]-4' -n-fluorobutyrophenone (Haldol),the representative of several related classes of aromaticbutylpiperidine derivatives, is a potent antipsychotic usefulin schizophrenia and in psychoses associated with braindamage. It is frequently chosen as the agent to terminatemania and often used in therapy for Gilles de la Tourettesyndrome. Haloperidol-induced dyskinesias may involveneurotoxicological metabolite similar to dopaminergic toxicantMPP+.

Pharmaceutical Applications

Haloperidol is an analogue of the dopamine D2 receptor antagonist and is an older antipsychotic drug. The drug is used in the treatment of schizophrenia, a neuropsychiatric disorder. In general, antipsychotic drugs work by blocking the dopamine D2 receptors.
Haloperidol is such an antipsychotic drug, which was developed in the 1950s and entered the clinic soon after that. Its use is limited by the high incidence of extrapyramidal symptoms (movement disorders caused by drugs affecting the extrapyramidal system, a neural network which is part of the motor system). Nevertheless, haloperidol may be used for the rapid control of hyperactive psychotic states and is popular for treating restlessness in the elderly.

Biological Activity

Dopamine antagonist with selectivity for D 2 -like receptors (K i values are 1.2, ~ 7, 2.3, ~ 80 and ~ 100 nM for D 2 , D 3 , D 4 , D 1 and D 5 receptors respectively). Subtype-selective NMDA antagonist.
