Abstract

Solid dispersions of mefenamic acid, azapropazone, glafenine and floctafenine were prepared with PVP K25 and PEG 6000 in a ratio of 1:1 w/w. Bioavailability and erosive activity of these drugs were investigated using their solid dispersions. The obtained results revealed that the coprecipitate of such drugs with PVP enhances their bioavailability and significantly inhibits the ulcerogenic effect of the drugs under investigation. However, solid dispersions with PEG enhance bioavailability but slightly reduce their gastric ulceration.
