The Impact of Sex and Age on Antipsychotic Serum Concentrations

We found sex differences in olanzapine and clozapine concentrations, which were most pronounced until 45 years of age. Our findings suggest that monitoring antipsychotic levels may add clinical value and underscore the need for sex-specific prescription guidelines for olanzapine and clozapine.

Abstract

We found sex differences in olanzapine and clozapine concentrations, which were most pronounced until 45 years of age. Our findings suggest that monitoring antipsychotic levels may add clinical value and underscore the need for sex-specific prescription guidelines for olanzapine and clozapine.
