1. Preparation of anti-acid capsules
Glycerin 22.02kg, distilled water 34.13kg, simethicone 10kg, 43.85kg gelatin is added, and it is dissolved under reduced pressure at 70～80℃, and it is made into capsules by usual method. It is prepared by spraying a mixture of formaldehyde/acetone (1/60) on the capsules. Due to the hydrophobic effect of simethicone, the prepared capsules will not disintegrate in acidic gastric juice for 2 hours, and dissolve in alkaline intestinal solution for 200-620 seconds, are stable to enzymes and temperature, and have good mechanical strength.

2. Polishing of sugar-coated tablets (gloss retention agent)
During the polishing operation, add 2% Sichuan wax powder with 2% simethicone oil to the colored-coated tablets for polishing. Compared with the sugar-coated tablets without simethicone, the surface of the sugar-coated tablets is brighter and more beautiful. Moisture-proof effect, to ensure that the sugar-coated tablets will not decolor or mold during the storage period.

3. Film coating material
Used as a plasticizer for film coating materials, using the hydrophobicity and oxygen resistance of simethicone to isolate the core from the outside, free from moisture, oxygen, etc. in the air, without moisture absorption and deterioration, and the coating layer is firm and smooth.
