Abstract
Obesity is a metabolic condition that accounts for life-threatening disorders like cancer, cardiovascular diseases, and type 2 diabetes. There are several anti-obesity drugs currently available on the market, but many of them show poor bioavailability due to low water solubility. Several attempts have been made by researchers to improve the solubility of orally administered drugs, but many of them did not work properly. Herein, we introduced a block copolymer micelle consisting of poly (lactic acid)-co-poly (ethylene glycol) to improve the solubility of the anti-obesity drug "Fenofibrate.” The block copolymer was synthesized using the polycondensation method, while the micelle was formed when water was added dropwise to the copolymer. Finally, laser light scattering and DLS analysis were used to confirm the micelle formation. The size of the micelle increased from 158 nm to 249 nm after the fenofibrate drug loading inside the hydrophobic core. The polymer PLA-co-PEG can be used as a carrier for orally administered fenofibrate drugs in the future for better water solubility and efficiency.
