Prostaglandin-lipid formulations. |
摘要 |
<p>A liposome composition and methods for making same are disclosed, such compositions comprise an arachidonic acid metabolite such as a prostaglandin, preferably prostaglandin E1, a lipid, and a drying protectant such as a saccharide. The liposomes may be loaded with prostaglandin passively, or using a transmembrane concentration gradient, preferably using a transmembrane pH gradient. Using this transmembrane loading technique, trapping efficiencies of 50% to 100% are achieved, and the release rate of the prostaglandin from the liposomes is reduced. The liposome size is maintained after lyophilization and reconstitution.</p> |
