ओलैंज़ापिन और फ्लुओक्सेटिन और वैल्प्रोइक एसिड का इंटरैक्शन

Co-administration of valproate (500 mg BID) and olanzapine (5 mg) to healthy adults (n=10) caused 15% reduction in C max and 35% reduction in AUC of olanzapine.

In contrast, drugs that are inhibitors of cytochrome P450 isozymes, e.g., antidepressants, may be expected to have little effect on valproate clearance because cytochrome P450 microsomal mediated oxidation is a relatively minor secondary metabolic pathway compared to glucuronidation and beta-oxidation.

Olanzapine No dose adjustment for olanzapine is necessary when olanzapine is administered concomitantly with valproate.
