제목 | Preparation and characterization of Aceclofenac using self micro emulsifying drug delivery systems (SMEDDS) |
초록 | Aceclofenac is 2-[(2,6-Dichlorophenyl) amino] benzeneacetic acid carboxymethyl ester and is used as anti-inflammatory drug(NSAIDs).1,2 Aceclofenac inhibits the cycle-oxygenase enzyme system and hence reduces the biosynthesis of prostaglandins.3 Because aceclofenac is lipophilic material, it is easily dissolved in oil. Therefore, self-micro emulsifying drug delivery system (SMEDDS) was applied to improve drug solubility and bioavailability. In this study, PEG(MW=200, or 400), Labrafil, and Cremophor as cosurfactant, oil and surfactant were orderly mixed with Aceclofenac for formulation of SMEDDS. Droplet size of SMEDDS into water was determined 20~25㎚ size.(그림. 1) In vivo experiment was performed in rat at the pre-determined set time. we extracted serum from the rat and quantitatively analyzed drug concentration by HPLC. From these results, we could achieve the improved drug solubility and bioavailability using the SMEDDS.(그림. 2) Fig. 1. Particle size of SMEDDS. Fig. 2. Release test of Aceclofenac in vivo.
