Study Notes

Capsule Types and Components

Slow-release capsules and gastro-resistant capsules differ in their release mechanism: slow-release capsules release the active ingredient over an extended period, whereas gastro-resistant capsules protect the active ingredient from stomach acid and release it in the intestines.

Capsule Shell Composition

The primary component of the capsule shell is gelatin, derived from animal sources (bones, skin, and connective tissue) and bone-based sources (bones and bone marrow).

Gelatin Types

Type A gelatin is derived from acid-treated raw materials, whereas Type B gelatin is derived from alkaline-treated raw materials.

Capsule Shell Functionality

Opaquants are added to the capsule shell to provide opacity and prevent the entry of light, which can affect the stability of the active ingredient.

Hard-Shell vs. Soft-Shell Capsules

Hard-shell gelatin capsules have a rigid, two-piece shell that is filled with the active ingredient, whereas soft-shell gelatin capsules have a flexible, one-piece shell that is filled with the active ingredient.
