Abstract

Microencapsulations of piroxicam using the mixture of Eudragit RS with RL or Eudragit L or E or S according to Eudragit RS were carried out. The Eudragit microspheres of piroxicam were prepared by solvent method. Piroxicam and Eudragit polymer were dissoved in methylene chloride and dispersed in 0.5% pOlyvinyl alcohol solution and solvent evaporated. The average diameters of various Eudragit microspheres were from 40 to 43${\mu}{\textrm}{m}$. A good and smooth surface of microspheres observed by SEM were shown in all type of microspheres.
