Aripiprazole exposures reported to Texas poison control centers during 2002-2004.
Aripiprazole is an oral atypical antipsychotic drug used in the treatment of schizophrenia and potentially other behavior disorders. The purpose of this study was to describe the epidemiology of aripiprazole exposures reported to Texas poison control centers. Human aripiprazole exposures reported to six Texas poison control centers were identified and comparisons were made between isolated and nonisolated cases with respect to various demographic and clinical factors. Of 280 human exposures involving aripiprazole, 35% were isolated and 65% were nonisolated. The patients were female in 52% of isolated and 60% of nonisolated cases. Isolated cases were significantly more likely to involve children < 6 yr of age. Fifty-eight percent of isolated cases were unintentional while 68% of nonisolated cases were intentional. Nonisolated cases were much more likely to already be at or en route to a health care facility when the poison control center was contacted. Of those cases with a known medical outcome, no adverse clinical effect was reported in 52% of isolated cases and 35% of nonisolated cases. The adverse clinical effects associated with isolated aripiprazole exposures were mainly neurological, cardiovascular, and gastrointestinal, with the most frequently reported adverse clinical effect being drowsiness or lethargy. The most commonly reported treatments for isolated aripiprazole exposures were single dose of activated charcoal, cathartic, intravenous fluids, dilution, lavage, and antihistamines. In conclusion, isolated and nonisolated aripiprazole exposures varied with respect to patient age, exposure reason, management site, and clinical outcome.
