Theophylline microspheres were prepared by the emulsion-solvent evaporation method using cellulose acetate butyrate (CAB381-20) and mixtures of CAB381-20(R) and cellulose acetate phthalate. The physical state of the drug, polymers and microspheres surfaces were determined using scanning electron microscopy. For those
