A mucosal formulation for administration to mucosal membranes, such as in the mouth, nasal passage, stomach, vagina, etc., is disclosed. The mucosal formulation contains a lipid-pharmaceutical agent complex formed from phospholipids possessing a hydrophobic moiety that orients into a hydrophobic phase and a polar head moiety that orients towards the aqueous phase (i.e., “amphipathic” lipids). When placed in an aqueous medium (e.g., vaginal fluid), the phospholipids form liposomes or other small lipid vesicles (e.g., micelles) that may then be used to deliver pharmaceutical agents into a living organism.
揭示了一种用于给粘膜膜的制剂,例如口腔、鼻腔、胃、阴道等。这种粘膜制剂包含从
磷脂中形成的含有疏
水部分的脂质-药物复合物,该疏
水部分朝向疏
水相,极性头部分朝向
水相(即“两性”脂质)。当置于
水性介质中(例如阴道液),
磷脂形成脂质体或其他小的脂质囊泡(例如胶束),然后可用于将药物输送到活体内。
