A method of preparing liposomal statins includes preparing a lipid solution including phosphatidylcholine, cholesterol, vitamin-E and an organic solvent and removing the solvent, forming a lipid cake. The lipid cake may then be hydrated with a first aqueous media. The hydrated cake may be mixed in a mixer and subjected to one or more freeze/thaw cycles and then extruded to form liposomes. A cryo-protective agent may be added to the liposomes and the liposomes may be lyophilized to provide a powder. A statin is added to the organic lipid solution or to the first aqueous media used for hydrating the lipid cake.
一种制备脂质体他汀类药物的方法包括制备包括
磷脂酰
胆碱、
胆固醇、
维生素-E 和有机溶剂的脂质溶液,然后除去溶剂,形成脂饼。然后用第一种
水介质将脂质饼
水合。
水合后的脂饼可在混合器中混合,并进行一次或多次冷冻/解冻循环,然后挤出形成脂质体。脂质体中可加入低温保护剂,然后将脂质体冻干,制成粉末。在有机脂溶液或用于
水合脂饼的第一种
水介质中加入他汀类药物。
