For patients hospitalized with acute episodes of psychosis, rapid stabiliza
tion of intense positive symptoms, hostility, and agitation is typically a
preeminent therapeutic goal. These goals often differ from those of the non
hospitalized patient with psychosis for whom long-term treatment goals such
as improvement of negative symptoms, cognitive function, compliance, and r
eduction in side effect burden may be paramount. Therefore, when selecting
an antipsychotic treatment for hospitalized patients, efficacy against posi
tive symptoms and hostility as well as speed of therapeutic onset should st
rongly be considered. At the same time, selection of antipsychotic treatmen
t in the inpatient setting should establish a definitive treatment that wil
l address long-term goals effectively after discharge. This article present
s the rationale and practical guidelines for selection of treatment regimen
s for patients hospitalized due to acute psychosis.
