Comparative Study
Risperidone liquid concentrate and oral lorazepam versus intramuscular haloperidol and intramuscular lorazepam for treatment of psychotic agitation.
Although agitation associated with psychosis is a common presentation in the psychiatric emergency service, there is no consensus concerning the best treatment. Standard treatment often consists of intramuscular (i.m.) injection of high-potency neuroleptics, sometimes combined with benzodiazepines. The objective of this study was to determine the relative efficacy, safety, and tolerability of oral risperidone versus intramuscular haloperidol, both in combination with lorazepam, for the emergency treatment of psychotic agitation in patients who are able to accept oral medications. ⋯ Oral treatment with risperidone and lorazepam appears to be a tolerable and comparable alternative to intramuscular haloperidol and lorazepam for short-term treatment of agitated psychosis in patients who accept oral medications.
