Theophylline-Ethylcellulose Microparticles: Screening of the Process and Formulation Variables for Preparation of Sustained Release Particles
OBJECTIVE(S): The aim of this study was to formulate and evaluate microencapsulated controlled release preparations of theophylline using ethylcellulose as the retardant material with high entrapment efficiency. MATERIALS AND METHODS: Microspheres were prepared by water-in-oil-in-oil (W/O(1)/O(2)) e...
