Pharmaceutical composition for reducing local fat and uses thereof
The present invention provides a pharmaceutical composition for reducing localized fat, comprising drug-containing micelles made of surfactants, and curcumin encapsulated in said drug-containing micelles. This pharmaceutical composition for reducing localized fat can reduce the fat at the administration site, and has the advantages of high stability, high bioavailability for fat tissue, few side effects, and sustained release.
