摘要：

Provided is a liposomal sustained-release composition comprising a therapeutic agent and one or more lipids. The therapeutic agent and total lipids are present in the liposomal sustained-released composition at a predetermined ratio. The liposomal sustained-release composition achieves a desired therapeutic effect while avoiding undesired side effects. The therapeutic agent is stably entrapped in the liposomes of the composition and sustainably released therefrom. This liposomal formulation for the therapeutic agent demonstrates an improved release profile.
