HALOPERIDOL

HALOPERIDOL




Haloperidol, m.p. 148-150°, is a white to faintly yellowish, oldourless, amorphous or microcrystalline powder. It is practically insoluble in water; soluble in alcohol (1 in 5O), chloroform (1 in 20) and slightly soluble in ether; stored in airtight containers and protected from light.



Uses : Haloperidol is a butyrophenone with actions and uses similar to those of the phenothiazine, chlorpromazine. It is a major tranquillizer used in the management of the agitated states, mania, aggressiveness and hallucinations. It is used for its sedative and potent anti-emetic effects.

Adverse Effect


The adverse effects of haloperidol resemble to those of phenothiazines with a piperazine side chain. The extrapyramidal reactions, parkinson-like symptoms, impaired liver function and blood dyscrasias are observed as side effects.
