摘要:
Disclosed is a sustained-release lipid pre-concentrate, comprising: a) at least one liquid crystal former; b) at least one phospholipid; c) at least one liquid crystal hardener; and d) at least one bi- or multivalent metal salt, wherein the sustained-release pre-concentrate exists as a lipid liquid phase in the absence of aqueous fluid and forms into a liquid crystal upon exposure to aqueous fluid. The sustained-release lipid pre-concentrate is configured to enhance the sustained release of anionic pharmacologically active substances through ionic interaction between the bi- or multivalent metal salt and the anionic pharmacologically active substances.
