A comparative pharmacokinetic study was performed with two types of suppository each containing 20 mg piroxicam. The bioavailability
of piroxicam was studied in 24 healthy volunteers in a double blind, randomised, cross over study.
No significant difference was found in the pharmacokinetic parameters [AUC(0–72 h), AUC, Cmax, t1/2β calculated from plasma concentration time curves, indicating that the two preparations were bioequivalent.
