The results of a population pharmacokinetic (PPK) analysis for Japanese suggest that smoking and gender difference are factors influencing the clearance of olanzapine, an atypical antipsychotic drug. However, no post-marketing verification has been conducted regarding how these factors affect the prescribing of this drug by practicing physicians. We therefore conducted a retrospective analysis on the effects of smoking and gender difference on olanzapine dosages. The results showed that smokers received significantly higher doses of olanzapine than non-smokers and that males tended to receive higher doses of olanzapine than females. The dosage for male smokers, the highest dose group, was 1.3 times that for female non-smokers, the lowest dose group. These results showed good correspondence with those of the PPK analysis given in the package insert and suggests that PPK data could be useful information for the community pharmacist.
