Currently, gelatin hollow capsules
are the most widely used capsules. These capsules can contain a variety of drugs, including solid, liquid, and powdered drugs. Besides, these capsules can be transparent, translucent, or opaque.
The major component of gelatin hollow capsules is high-quality medicinal gelatin. This material is derived from collagen in animal bones and skin. It has excellent biocompatibility and film formation. These characteristics help to prevent the degradation of the contents in the capsules.
However, these capsules are not suitable for everyone's diet. Some people have allergies to certain ingredients. If you are allergic to pork, beef, or poultry, you should not consume these types of gelatin.
During the production process, the gelatin is made by filming it onto a stainless steel mold. After the capsule is removed from the mold, it is capped with a cap. It is a relatively simple and straightforward process.
The empty gelatine capsules are easy to swallow. They are commonly used in the pharmaceutical industry to dose supplements and other drugs. They can mask the unpleasant taste and smell of the drug, so consumers can consume them with ease.
Unlike the HPMC hollow capsules, the gelatin hollow capsules are brittle under low humidity conditions. This may affect the drug itself.
Moreover, the HPMC hollow capsules are not prone to cross-linking. Therefore, they are able to be transported and stored safely. They are also stable under high humidity conditions. In short, the HPMC hollow capsules have obvious advantages over the gelatin hollow capsules.
