Mechanism of action of Haloperidol
Haloperidol (hal" oh per' i dol) is a butyrophenone derivative which appears to act as a dopamine type 2 (D2) receptor antagonist, but has other central and peripheral effects. Haloperidol is indicated for the therapy of acute and chronic psychoses and for controlling tics and vocal utterances in Tourette syndrome. Haloperidol is also used for short-term treatment of severe behavior problems in children with hyperactivity.
FDA approval information for Haloperidol
Haloperidol was approved for use in the United States in 1967, but is currently infrequently used, having been replaced in large part by the atypical antipsychotics, which have fewer extrapyramidal side effects.

Haloperidol is available as tablets of 0.5, 1, 2, 5, 10 and 20 mg, as an oral solution and in several formulations for parenteral use in generic forms and under the brand names Haldol and Peridol.
