The objectives of this study were to develop an electrostatic dry powder coating process for sustained coating tablets with Eudragit(®) RS/RL and to investigate the effects of various factors and operating conditions on the coating process and drug release profile. A liquid plasticizer (triethyl citrate) was sprayed onto the surface of the tablets followed by spraying coating powder by an electrostatic spray gun. The powder coated tablets were cured at elevated temperature for a film formation… CONTINUE READING
