The purpose of the present study was to prepare and evaluate self-emulsifying drug delivery system (SEDDS) of curcumin (Cur) to enhance its solubility and percentage release for the evaluation of anti-inflammatory effect. Curcumin loaded SEDDS formulation was prepared, and zones of self-emulsification were recognized by dilution method for the construction of phase diagram. Lauroglycol FCC, tween 80 (surfactant), and transcutol HP (co-surfactant) were selected based on their solubility and highest emulsion region in phase diagram. Thermodynamic stability of Cur-SEDDS was calculated through globule size, zeta potential, polydispersity index (PDI), viscosity, and pH. Cur-SEDDS were also characterized by encapsulation efficiency (EE %), FT-IR, in vitro release, and in vivo anti-inflammatory effect. Results revealed that droplet size of Cur-SEDDS was 19.77 ± 0.03 nm with their PDI 0.22 ± 0.19, zeta potential −19.33 ± 0.94 and viscosity 25.68 ± 0.86 cp. EE % of Cur-SEDDS was found to be 94.99 ± 0.38%, percentage release 65.83% compared with pure Cur powder. The designed formulation possesses significant anti-inflammatory activity in paw edema when compared with positive control in carrageenan induced rat paw edema assay. Newly developed Cur-SEDDS with enhanced Cur solubility, percentage release, and better anti-inflammatory action may be an alternative source of oral delivery of Cur. [ABSTRACT FROM AUTHOR] |
