Bioequivalence of two oral dosage forms prepared from different polymorphic modifications of tenoxicam.
The bioavailability of two pharmaceutical dosage forms formulated using different polymorphs of tenoxicam were compared. Serum levels of TNX were analysed using high performance liquid chromatography. The pharmacokinetic parameters were estimated following the oral administration of a single dose (20 mg) of the drug as two different polymorphs to 12 healthy volunteers. The differences between formulations were statistically insignificant.
