Application:
Coating of tablets, granules, and pills:
n Moisture-proof and light-proof. Maintain drug stability in tropical environments. Orally resistant to gastric acid (liquid) to delay intestinal release.
n Separate porous tablet cores and hygroscopic tablet core openings to isolate incompatible ingredients
n Granulation can be used as a matrix material to increase the coating weight and delay the release of drugs.
