Hard shell gelatin capsule is a dosage form widely used in medicine, health care products and other fields.

1. Structure and material

Shell

The shell of hard shell gelatin capsule is mainly made of gelatin. Gelatin is a protein extracted from connective tissues such as animal skin and bones, which has good film-forming and plasticity. This shell is hard and smooth, and can effectively wrap the medicine or nutrients inside.

The shape of the capsule is usually a cylinder with slightly rounded ends, which is easy to swallow and can maintain a stable shape during storage and transportation.

Sealing performance

The hard shell of the capsule can provide an excellent sealing effect. It can prevent the active ingredients inside from being affected by external environmental factors such as air, moisture and light. This helps to maintain the stability of the medicine or health care products and extend their shelf life.

2. Functional advantages

Precise dosage

For drugs, hard shell gelatin capsule can accurately hold a certain amount of drug powder or granules. Pharmaceutical companies can determine the size of the capsule and the filling amount of the contents according to the effective dose of the drug to ensure that the patient takes the correct dose each time.

Masking bad taste

In health products and some medicines with special smells or tastes, the hard shell of the capsule can effectively mask the bad taste of the internal ingredients. For example, health products such as fish oil may have a fishy smell. After being wrapped in a capsule, the patient or user will not feel this unpleasant taste when swallowing.

Convenient to take

Compared with other dosage forms, such as tablets that may need to be chewed or powders that may not be easy to swallow, hard shell gelatin capsules can be taken directly with water, which is simple and convenient to operate. Especially for children, the elderly or patients with dysphagia, the shape and smooth surface of the capsule make it easier to swallow.

However, it should be noted that since gelatin comes from animals, vegetarians or people with special religious beliefs may need to choose capsule substitutes made of plant gelatin. At the same time, it should be stored in accordance with the prescribed conditions to ensure the quality of the capsule and the effectiveness of the internal ingredients.
