First of all, the main raw material of HPMC capsules is medicinal hydroxypropyl methylcellulose (HPMC), which is the most abundant natural polymer in nature.
Physically extracted from marine or terrestrial plants; gelatin capsules
It is medicinal gelatin, which is chemically extracted from the skin, tendons, and bones of animals (mainly pigs, cattle, and sheep).
HPMC in HPMC capsules is stable (non-reactive with air and water) and does not react with some drugs. Wide adaptability, stable drug release rate, complete dissolution, more significant curative effect, and small individual differences.
HPMC still has a natural concept after being made into capsule shells, and no preservatives need to be added during the production process; gelatin capsules are easy to breed bacteria and microorganisms, so preservatives need to be added during the production process (resulting in Nipagin preservatives, ethylene glycol, and chlorine residual ethanol).
Not brittle in low humidity conditions, but stable in high humidity conditions. It will not soften, deform or harden and become brittle at a temperature of 10-40°C and a humidity of 35-65%. Gelatin capsules dehydrate and harden in low humidity conditions and bond in high humidity conditions.
The storage and transportation conditions of gelatin capsules are strict. HPMC is metabolically inert, cannot be absorbed in the body, and is directly excluded from the body. Plant capsules are not easy to breed microorganisms, and they will not decompose and deteriorate when stored for a long time. The normal validity period is 36 months.
The raw materials of HPMC capsules come from natural plants, which provides a better choice for vegetarians and patients of different religious beliefs.
The identification of HPMC capsules is also simple. If the capsule shell is ignited, HPMC capsules will smell of burning cotton, while gelatin capsules will smell of burning protein (similar to the smell of burning hair).
