Enteric-coated gelatin capsules consist of a hollow capsule coated with an enteric coating. The enteric coating material is primarily cellulose esters. The manufacturing process involves preparing a gelatin solution and a coating solution, dipping the capsule in the gelatin solution, drying it, dipping it in the coating solution again, drying it a second time, demolding, cutting, and assembling it to form an enteric-coated hollow capsule.
Enteric-coated gelatin capsules are hollow hard capsules made with capsule-grade gelatin, excipients, and suitable enteric materials. They are divided into two types: ordinary enteric-coated capsules and colonic enteric-coated capsules. The term "enteric-coated" indicates its purpose is to release contents into the small or colon, and "gelatin" is its main film-forming material. This product is available in transparent, semi-transparent, and opaque varieties. It is classified as a pharmaceutical excipient used in the preparation of delayed-release capsules.
