There are many kinds of medicinal empty capsules.
From the raw materials, it can be divided into traditional capsules (also known as gelatin capsules, animal based capsules) and plant capsules (also known as empty vegetable capsules/ veggie capsules/ vegetarian capsules). Traditional capsules are made of animal skin, bones and tendons, and are made of complex physicochemical treatments. They are fat-free, high-protein, easily absorbed by the human body, and have physical characteristics such as high viscosity, high freezing force, and easy freezing.
Plant capsules (also known as halal capsules) are empty capsules made from plant cellulose or water-soluble polysaccharides. The cellulose is HPMC (Hydroxy propyl methyl cellulose). Generally, cotton or wood pulp are used as raw materials of HPMC. All contents likecarrageenan, pectin, agar, sodium alginate and guar gum are all extracted from plants, and some of their characteristics are the same as animal gelatin.
In terms of physical shape, medical capsules can be divided into hard capsules and soft capsules (also known as capsules). Hard capsules are made of a certain amount of drugs (or medicinal material extracts) and appropriate auxiliary materials (without the addition of auxiliary materials) into uniform powder or granules, which are filled in hollow hard capsules. Soft capsule is to dissolve a certain amount of drug (or medicinal material extract) in appropriate auxiliary materials, and then use a compression method (or drop method) to make it sealed in a spherical or olive-shaped soft capsule.
Depending on where the drug is released in the body, capsules can also be divided into stomach-soluble and enteric-soluble types. The stomach-soluble type is to release the medicine enclosed in the capsule in the stomach, while the enteric-type is to add a special medicinal polymer material to the capsule shell or undergo special treatment to make it insoluble in the gastric juice and only melt in the intestinal juice. Release active pharmaceutical ingredients. According to the size of the capsule, there are several types. Current popular sizes of empty capsules are size 000, size 00, size 0, size 1, size 2, size 3, size 4, and size 5.
No matter what kind of pharmaceutical capsules, it is necessary to blend the main ingredients of the capsules-pharmaceutical gelatin, edible gelatin and food coloring and other auxiliary materials into liquid raw materials, and then put them into the molded mold for compression molding and then trim and package . After that, the pharmaceutical company puts powder or liquid medicine into such capsules to make capsule medicine. Capsules are generally double-locked, that is, after the capsules are produced, they are pre-closed before being filled with drugs, and are completely locked together after being filled with drugs.
