What are the introductions of capsules?

Update:22 Dec 2020

The drugs packed in capsules are generally powders or granules that are irritating to the esophagus and gastric mucosa, or have a bad taste, are easy to volatilize, are easily broken down by saliva in the oral cavity, and are easily inhaled into the trachea. These medicines are packed into capsules, which not only protects the properties of the medicines from being destroyed, but also protects the digestive organs and respiratory tract. Removing the capsule shell may result in loss of medicine, waste of medicine, and reduced efficacy. In addition, some drugs need to be dissolved and absorbed in the intestine, and the capsules protect the drugs from being destroyed by gastric acid.



Main classification
There are usually hard capsules and soft capsules. Hard capsules, also known as hollow capsules, consist of two parts of the cap; soft capsules are processed into products with film-forming materials and contents at the same time.

Hard capsules are classified according to the raw materials. The capsules generally include:
Gelatin capsule
Gelatin capsules are the most popular two-piece capsules in the world.
The capsule consists of two precision-machined capsule shells. There are various capsule sizes, including 000#, 00#, 0#--5#=capsules. The capsules can also be colored and printed to present a unique customized appearance.
The capsule body part has a tapered edge, and the capsule can be sealed smoothly on the high-speed filling machine. The double-locking ring system allows the capsules to be pre-closed before filling, and completely fitted together after filling with medicine. The design of the capsule also includes vents to avoid unnecessary air pressure inside the capsule during high-speed filling and causing rebound.

Plant capsule
Plant capsules are hollow capsules made of plant cellulose or water-soluble polysaccharides as raw materials, such as Qianlie Vigor, to meet the needs of all-natural positioning and capsule formulation solutions. It retains all the advantages of standard hollow capsules: convenient to take, effective in concealing taste and smell, and the contents are transparent and visible, etc., and at the same time has the connotation that traditional gelatin capsules do not have.
