The characteristics of liposome technology have improved the multiple applications of many products that are difficult to dissolve and not easy to store, such as Liposomal Vitamin C. It improves bioavailability, stability, enhances product absorption, reduces adverse reactions. And it has an excellent clinical performance.
Liposomes generally refer to small closed vesicles with bilayer-encapsulated water phase structures formed by dispersing lipids such as phospholipids in water. Because their system is similar to biological membranes, they can also be called artificial biological membranes. So, what are the advantages of liposomes?
1. Various routes of administration: In addition to the most common way of administration by injection, liposomes are also suitable for oral administration, ocular administration, pulmonary inhalation administration, and transdermal administration.
2. Targeting: Ordinary liposomes have liver and spleen tissue targeting. Liposomes can have specific targeting after being modified by monoclonal antibodies and other antibodies.
3. Long-acting: long-circulating liposomes can prolong the retention time of the drug in the blood, which is beneficial to increase the drug's efficacy.
4. Good histocompatibility: Liposomes have good cell affinity and histocompatibility with a structure similar to that of biological membranes. It can be adsorbed around target cells for a long time and directly enter cells through lysosomes. Digestion releases drugs.
5. Reduce drug toxicity: After liposomes encapsulate the drug, the cumulative amount in the heart and kidney is much lower than that of the free drug. Therefore, drugs that are toxic to the heart and kidney can be prepared into liposomes to reduce drug toxicity.
6. Drug stability: Some dangerous drugs in a specific environment can be protected by the liposome bilayer to improve the strength of some medications.
The liposomal vitamin C prepared by HSF is based on the characteristics of liposomes to improve the stability of VC and has been applied on a large scale. It has played a better role in promoting human health.
