Pharmacokinetic studies in healthy volunteers on a new gastroprotective pharmaceutic form of diclofenac.

The pharmacokinetic properties of a new gastroprotective pharmaceutical formulation of diclofenac (CAS 15307-79-6) were investigated in twelve healthy volunteers. In this new form the diclofenac is the nucleus of sequential sucralfate-covered tablets. The experimental design was an open, random, two period balanced cross-over study. All the subjects received a single oral dose of 50 mg diclofenac contained in the new formulation or in the reference enteric-coaled tablets. Plasma concentrations of diclofenac were determined at 0.5, 1, 2, 4, 6, and 8 h after drug administration using HPLC method
