PREPARATION AND CHARACTERIZATION OF ORAL NANOSUSPENSION LOADED WITH CURCUMIN
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2018, Vol 10, Issue 6
Abstract
Objective: The principle objective of the present research work was to improve the bioavailability of curcumin (CUR) by decreasing its particle size. Nanosuspension (NS) of CUR was prepared using poloxamer-188 (P188) as a surfactant. The prepared NSs were characterized for particle size, polydispersity index (PDI), zeta potential, drug loading, saturation solubility, and drug release kinetic studies.Methods: Components required for NS preparation, such as solvent, anti-solvent and surfactant were screened. Precipitation high-speed homogenization (HSH) method was used for the preparation of NS using selected components. Evaluation of NS for particle size, PDI, drug loading, saturation solubility and in vitro drug release was done. Pharmacokinetic studies of the NS in sprague dawley (SD) rats were performed.Results: The particle size, PDI and zeta potential of the optimized formulation was 596.5±5 nm, 0.233±0.010 and-23±2 mV respectively. The pH of all the formulations was in the range of 5-6 which is acceptable when related to drug stability. The optimized formulation showed an increase in saturation solubility in water and phosphate buffer pH 6.8 when compared to plain CUR suspension (S). Results of pharmacokinetic studies indicated that Cmax and AUC0-6 were increased 8 and 10 times respectively from plain CUR S to CUR NS.Conclusion: CUR NS was prepared using P188 as the stabilizer. Amongst various stabilizers screened P188 rendered a stable NS with the particle size in nano range. Pharmacokinetic studies revealed the better performance of CUR NS as compared to plain CUR S.
