Injectable composition for localized fat reduction without pain, edema, and side effects, and method for preparing same

Abstract

The present invention relates to a composition comprising glycocholic acid or taurocholic acid and phosphatidylcholine at a particular mixing ratio for reducing localized fat without side effects such as a pain, edema, necrosis of muscle cells, fibroblasts and vascular endothelial cells other than adipocytes, anesthesia of administration sites, extensive swelling, erythema, induration, paresthesia, nodule, pruritus, burning sensation, nerve injury, and dysphagia, and a method for preparing the same. The inventor has found that the effect of PPC injectable composition on fat reduction may be reduced or enhanced during its subcutaneous administration, depending on the types of solubilizing agents, especially the types of bile acids, which are combined so as to prepare a safe and stable PPC injection using insoluble PPC. The PPC injectable composition solubilized with GCA or TCA selectively reduces adipocytes without inducing necrosis of fibroblasts, muscle cells and vascular endothelial cells, thereby alleviating the known clinical side effects.
