The bioavailability and pharmacokinetics of mefenamic acid in alloxan-diabetic rabbits

The bioavailability and pharmacokinetics of mefenamic acid was studied in alloxan-diabetic rabbits. Mefenamic acid in plasma was assayed by high performance liquid chromatography. A paired t-test for normal and alloxan treated rabbits revealed a significant decrease in all the bioavailability and disposition kinetic parameters of mefenamic acid during diabetes was observed in the present study. The altered bioavailability and disposition of mefenamic acid in the diabetic state will require adjustment of the dosage regimen prescribed for diabetics in a clinical setting.
