Abstract

An industrially feasible formulation approach combining media milling and spray-drying was applied to improve dissolu-
tion characteristics of the poorly soluble drug mefenamic acid (MA). The approach was studied for two MA polymorphs
at different stressing and pH conditions. It was found that final MA product particle sizes are rather determined by the
solid-liquid equilibrium than by mechanical fracture. Obtained drug particles are only composed of the most stable poly-
morph. Direct compressed tablets containing MA nanocrystals exhibit a significant improvement of in vitro dissolution
kinetics as compared to tablets with micronized drug particles.
