Medicinal enteric-coated gelatin hollow capsules are administered as intestinal positioning, reducing adverse reactions, and targeted and fixed-point release: no disintegration and no cracks in gastric juice for two hours, and disintegration of drugs in intestinal juice within 30 minutes. Live bacterial preparations provide a complete solution. Enteric gelatin hollow capsule is a targeted capsule product made of gelatin and enteric coating material, which does not disintegrate in gastric juice, but only disintegrates and releases in intestinal juice. It is often used in special packaging for drugs or health care products that are irritating to the stomach or are unstable in the presence of acid, and that need to be dissolved in the intestine and exert their curative effect. Intestinal-targeted drug delivery can improve drug efficacy and reduce dosage, and at the same time, it can reduce adverse reactions and facilitate the use of patients; it can also avoid the degradation of oral protein polypeptide drugs or health care products and provide them with an absorption site.
