Hydroxypropyl methylcellulose enteric empty capsule jellied by carrageenan and potassium citrate
A technology of hypromellose and potassium citrate, which is applied in the directions of capsule delivery, medical preparations of inactive ingredients, pharmaceutical formulations, etc., can solve the problems of insufficient film-forming properties and storage stability of capsules, and the disintegration rate of gelatin capsules. It can reduce the risk of drug hygroscopicity, no risk of animal infectious diseases, and not easy to rot and deteriorate.
