Abstract
Description
Technical field
[0001] The invention belongs to the field of pesticide additives, and more specifically, relates to a blank multivesicular liposome and a preparation method and device thereof.Background technique
[0002] Multivesicular liposomes (MVL) are composed of multiple non-concentric aqueous drug solution vesicles, which are separated by a continuous non-concentric lipid bilayer, and have a high encapsulation rate for water-soluble drugs. In particular, multivesicular liposomes release drugs through ruptured vesicles, while intact vesicles remain intact. The non-concentric topological structure of multivesicular liposomes makes it form a "reservoir" at the injection site. With the continuous degradation of the lipid bilayer, the drug encapsulated in it is gradually released, resulting in a good relief. The drug release effect is avoided while avoiding the sudden release effect, and the effect of controlling the drug release time from a few days to several weeks can be obtained by ...
