Pharmacotherapy of psychiatric emergencies.

The psychiatric emergency service has become a major provider of psychiatric care over the past decade. Concomitant with this growth has been an emphasis on pharmacological treatment. While rapid tranquilization is the best known and most frequently used intervention, a growing diagnostic awareness has led to a variety of other chemotherapeutic approaches. The current reviews of pharmacologic intervention in the psychiatric emergency service do not detail the variability of treatment approaches or examine alternative treatment approaches. The goal of this article is to critically review current pharmacologic treatments and address areas in which there is no consensus in treatment approach. From this review the authors suggest guidelines for pharmacotherapy of psychiatric emergencies. The authors discuss rapid tranquilization, the treatment of alcohol and drug intoxication and withdrawal, and anxiety disorders.
