Overview: efficacy and safety of the rapid neuroleptization method with injectable haloperidol.

The authors review the literature on the rapid neuroleptization (titration) method with I.M. haloperidol. Most of the approximately 650 predominantly schizophrenic and manic patients represented in the studies calmed down rapidly on medication, and some demonstrated an early reduction in core psychotic symptoms. The initial doses varied widely, ranging from 1 to 30 mg, with a maximum total daily dosage of 100 mg. The medication seemed to have been well tolerated in all cases, with no reported major complications. The authors conclude that the method shows definite merit with agitated and belligerent patients. However, they make a number of specific recommendations for further research to clearly establish the effectiveness and safety of this method of neuroleptic administration.
