The formulation of flurbiprofen loaded microspheres using hydroxypropylmethycellulose and ethylcellulose.

Abstract

This study demonstrated the potential of polymer combinations in the formulation of microspheres for water-insoluble drugs utilizing HPMC and EC as release retardant materials, using a simple solvent evaporation microencapsulation technique. It was observed that various physico-chemical properties of the microspheres varied according to the change in polymer concentrations used in the formulations.
