Empty HPMC capsules are a derivative of plant fiber, its main components are plant cell walls and polysaccharides, its molecular structure is very stable, and it has good film-forming properties. The three main characteristics are:
1. Safety: Since hypromellose is derived from non-transgenic plants, commonly known as the plant-sourced empty pharmaceutical capsule, its harmful substance residues are far lower than traditional capsules, and it does not contain protein and amino acids, plus special production The production process makes it difficult for bacteria to contaminate again, and there is no worry about residual chloroethane, which is safer.
2. Stability: Empty HPMC capsules are suitable for filling various contents, ensuring no cross-linking reaction, and stable sub-molecular structure. They are more suitable for filling oxygen-sensitive and immediate-release drugs, making the contents safer, more thorough dissolution, and better efficacy. more significant.
3. Universality: empty HPMC capsules have lower water content and better molecular structure, and are especially suitable for the filling of Chinese patent medicines. The requirements for storage, transportation, environment, and geography are lower than those of gelatin capsules. various ingredients as needed.
