A bioequivalence study of two brands of glipizide tablets

In this open, randomized, two way crossover, bioequivalence study, two 5 mg tablet preparations of glipizide (Glipizyd tabl. 5 mg, Tarchomińskie Zak?ady Farmaceutyczne POLFA S.A., and Glibenese tabl. 5 mg, Pfizer), were compared in 24 healthy male volunteers. Pharmacokinetic variables (mean maximum plasma concentration, mean time to reach maximum plasma concentration, and the mean area under the plasma concentration-time curve) were not statistically significantly different for the two formulations. It can be concluded that the two tablet preparations of glipizide are likely to be bioequivalent.
