It retains all the advantages of standard hollow capsules: convenient to take, effectively covering the taste and smell, transparent and visible contents, etc. At the same time, it has the connotation that traditional gelatin capsules do not have.
Extended data;
Capsules are generally divided into hard capsules and soft capsules. Hard capsules are mostly cylindrical shells. Soft capsules mainly contain drugs in liquid or suspended state, so the drugs in soft capsules are also called capsules.
Most capsule shells are made of gelatin. Gelatin is a kind of protein substance, which is mainly extracted from the skin, bones and tendons of animals. Glycerol or plasticizer is added in the production process. Gelatin has the characteristics of high viscosity and easy freezing. Insoluble in cold water, soluble in warm water. It can slowly absorb 5- 10 times its own weight, and then expand and soften. Enteric capsules are special.
Enteric hard capsule shell is made of cellulose acetate phthalate and other materials, while enteric soft capsule shell is usually made of calcium alginate.
