In the world of pharmaceuticals, the manufacturing of gelatin capsules is a meticulous process that directly impacts product quality. Here are some key technical considerations that ensure high-performance capsules.

1. Mechanical Resistance: Gelatin capsules are engineered to withstand mechanical stress. Identifying and eliminating weak points during production is crucial to prevent deformities that can affect efficacy.
2. Oxygen Permeability: Many active ingredients are sensitive to oxidation. Gelatin capsules provide an effective barrier, allowing minimal oxygen penetration, making them ideal for oxygen-sensitive formulations.
3. Active Pharmaceutical Ingredient (API) Dissolution: The dissolution rate of gelatin capsules in the stomach is exceptional, facilitating the rapid absorption of active ingredients. However, unfavorable conditions like humidity can lead to crosslinking, affecting performance.
4. Water Permeability: Understanding how much water a gelatin capsule can allow is vital, as moisture can influence the stability and effectiveness of the contents, depending on their composition.
5. Machinability: Gelatin’s high machinability means it can efficiently handle various mechanical processes without the need for additional gelling agents or adaptations. This streamlines production and enhances consistency.
