Gelatin capsules offer several benefits, including capsule protection, sustained-release, masking drug odors and bitterness, and increased drug stability.
1. Capsule Protection
By forming a barrier around the drug, gelatin reduces the impact of the external environment, ensuring the active ingredients are not compromised.
2. Sustained-Release Effect
Utilizing the difference in dissolution rate of the gelatin shell, the drug is released evenly, prolonging its duration of action.
3. Masking Drug Odors
Because gelatin itself is odorless and non-volatile, it can effectively mask certain drugs with irritating odors or those that are volatile.
4. Masking Drug Bitterness
Gelatin can encapsulate bitter-tasting drugs, reducing discomfort for patients.
5. Increasing Drug Stability
As a semi-permeable membrane material, gelatin can prevent moisture from entering the capsule under certain conditions, helping to maintain drug stability.
