What type of capsule contains a rigid shell composed of gelatin, sugar, and water?

A hard gelatin capsule contains a rigid shell made primarily of gelatin, along with additives such as sugar and water. This composition provides strength and stability to the capsule while allowing for the encapsulation of powdered or granular substances. Hard gelatin capsules are typically composed of two parts: the body and the cap, which create an enclosed space for the pharmaceutical material. They are designed to dissolve in the gastrointestinal tract, facilitating the release of the active ingredients.

This type of capsule is widely used for solid dosages because it can easily accommodate a variety of formulations, including powders, granules, and pellets. Additionally, hard gelatin capsules can be manufactured in various sizes, making them versatile for different applications in pharmaceutical development.
