Atypical antipsychotic use in a state hospital inpatient adolescent population.

Atypical antipsychotics are now the most commonly prescribed antipsychotics in young patients. These drugs are increasingly being used because of better tolerance and safety as seen in the adult populations. Youth with more severe psychopathology who are treated in the inpatient setting have been overlooked in much of the published research, and the extent of use and rationale in this population is unknown. This naturalistic retrospective study examined a population of adolescents in an inpatient state hospital setting with regard to their use of atypical antipsychotics. All patients who received an inpatient prescription for atypical antipsychotics between January 1, 1997 and June 1, 2000 and were ages 18 or younger at the time of medication initiation were included in the study. Twenty-three percent (88/380) of patients received an atypical antipsychotic: 68% (60/88) risperidone, 27% (24/88) olanzapine, and 5% (4/88) quetiapine. Psychotic disorders were considered as the primary diagnosis in only 17% of patients treated with atypical antipsychotics, and no particular diagnosis was predictive of monotherapy with an atypical antipsychotic. In the adolescent populations, atypical antipsychotics are being used for a wide variety of diagnoses and are commonly used adjunctively (more than 80%) with many concomitant psychotropic medications. More research is needed to develop useful and specific practice guidelines in children and adolescents for these commonly used medications.
