Gelatin is a versatile natural polymer. It has low immunogenicity, antibacterial property, anti-oxidation performance, etc. It can be applied to capsules, blood substitutes, hemostatic excipients, tissue engineering scaffold materials, and the like.
Gelatin can be used to make gelatin capsules. This kind of capsule is an excellent packaging material for tablets, which can protect the built-in medicines. It also reduces the chance of oxidation and moisture absorption of the tablets, and avoids damage to the drugs caused by high temperatures during processing.
Gelatin has low immunogenicity which is capable of preserving colloidal properties and has a relatively high molecular weight. It does not accumulate in the body after degradation and can participate in metabolism in the body as well as a large number of input non-toxic reactions.
Gelatin has good biocompatibility and biodegradability. It has breathable and moisture permeable properties similar to the skin, making it possible to apply it to skin hemostatic dressings. Studies have shown that gelatin has activated macrophages and hemostasis.
Gelatin can be applied to pharmaceutical additives as a stabilizer and excipient.
