RESUMO

Simple, sensitive and accurate spectrophotometric derivative methods were developed for the simultaneous determination of olanzapine and fluoxetine hydrochloride in pharmaceutical formulations by derivative spectrophotometry. On all orders of derivative studied, the linear response range was 10 to 60 mg L-1, with limit of quantitation (LoQ) ranging from 0.73 to 1.49 mg L-1 for fluoxetine hydrochloride and from 0.18 to 0.96 mg L-1 for olanzapine. The best orders for derivative analyses showed recoveries ranging from 99 to 103% and from 98 to 100%, and inter-day accuracy < 2.1% and < 2.8%, for fluoxetine hydrochloride and olanzapine, respectively.
