Applying a novel electrostatic dry powder coating technology to pellets
The present study aimed to apply a novel dry powder technology to coat pellets with different coating materials grounded into fine powders. Piroxicam, a non-steroidal anti-inflammatory drug, was used as the active pharmaceutical ingredient (API). Eudragit® EPO, Eudragit® RS/RL and Acryl EZE were used as the coating materials to achieve immediate release, sustained release and delayed release, respectively.
