Since the introduction of plant capsules in the United States in 2000, it has developed rapidly in Europe and the United States. The United States plans to increase the market share of plant capsules to 80% in recent years. What advantages will plant capsules have? Recognition of it. The first is the difference in raw materials. The main raw material of plant capsules is medicinal hydroxypropyl methylcellulose (HPMA), which is the most abundant natural polymer in nature.It is physically extracted from marine or terrestrial plants; gelatin capsules are medicinal gelatin. The collagen in the skin, tendons and bones of animals (mainly pigs, cows and sheep) is chemically extracted. The HPMC in plant capsules is stable in nature (not chemically reacted with air and water), and does not cross-link with some drugs. It has wide adaptability, stable drug release rate, complete dissolution, more significant curative effect, and small individual differences. After the capsule is made of HPMC, it still has a natural concept. The production process does not need to add any preservatives; gelatin capsules are easy to breed reproductive bacteria and microorganisms, and preservatives need to be added during the production process (resulting in paraben preservative residues and epoxyethanol, Chloroethanol residue, etc.).
The plant capsules are not brittle under low-humidity conditions, and the capsules can be kept stable under high-humidity conditions. The storage conditions are wide, and the temperature is between 10 - 40 ° C and the humidity is between 35 - 65%, which will not soften or harden and become brittle. Gelatin capsules lose water and harden under low-humidity conditions, and capsules adhere to high-humidity conditions, and storage and transportation conditions are relatively strict and demanding. HPMC is metabolically inert and is not absorbed in the body. It is directly excluded from the body. Plant capsules are not easy to grow microorganisms. They will not decompose and deteriorate after prolonged storage. The usual period of validity is 36 months. The raw material of plant capsules is derived from natural plants and provides a better choice for vegetarians and patients of different religious beliefs. The identification of plant capsules is also very simple, the capsule shell is ignited, the plant capsules have the taste of burning cotton, and the gelatin capsules are the smell of burning protein (similar to the taste of burning hair).
