What is the difference between plant hollow capsules and enteric hollow capsules?

There are significant differences between plant hollow capsules and enteric hollow capsules in terms of material sources, core functions, applicable scenarios, safety, and stability. The specific analysis is as follows:

Material source:

Plant hollow capsules: mainly made from plant extracts such as hydroxypropyl methylcellulose, pullulan polysaccharides, potato modified starch, seaweed polysaccharides, etc., without animal ingredients.

Enteric coated hollow capsules: usually made of gelatin and enteric coated materials (such as polyacrylic acid resin, cellulose acetate phthalate, etc.), divided into two categories: ordinary enteric coated and colonic coated.

Core functions:

Plant hollow capsules: mainly provide drug encapsulation function, mask drug odor, improve drug stability, and meet specific cultural and religious needs (such as vegetarians, Muslims, etc.).

Enteric coated hollow capsules: have gastric acid resistance, can disintegrate at specific sites in the intestinal environment (such as pH changes), and release drugs. This characteristic makes it suitable for drugs that need to be released in the intestine, such as medications for certain digestive system problems, protein peptide drugs, and live bacterial preparations.

Applicable scenarios:

Plant hollow capsules: suitable for people who are sensitive to animal derived ingredients and consumers who need green and natural products. It can be used to encapsulate various drugs, including Western medicine, traditional Chinese medicine, health products, etc.

Enteric coated hollow capsules: specifically designed to encapsulate drugs that are easily degradable or irritating to the gastric mucosa in the gastric environment. For example, certain drugs may become ineffective or have side effects in stomach acid, and enteric coated hollow capsules can ensure the release of these drugs in the intestine, thereby improving efficacy and reducing side effects.

Safety and stability:

Plant hollow capsules: free of animal protein and fat, not easy to breed microorganisms, safe and reliable in quality. Meanwhile, its low oxygen permeability (oxygen permeability is 1/300 of hydroxypropyl methylcellulose capsules and 1/8 of gelatin capsules) can protect the contents of the capsules from oxidation and extend their storage period.

Enteric coated hollow capsules: achieve targeted release in the intestine through special coating materials, but ensure the stability and safety of the enteric coated materials. In addition, the production process requires strict quality control to ensure that the capsules do not disintegrate in gastric juice and are released at designated locations in intestinal fluid.
