KINETIC MODELING OF RASAGILINE MESYLATE FROM NANOSCALE SOLID LIPID PARTICLES
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2015, Vol 7, Issue 11
Abstract
Objective: The present study is aimed to investigate the In-vitro release behavior of the Rasagiline mesylate loaded nanoscale solid lipid particles to provide the quality based controlled release system. Methods: The Rasagiline mesylate loaded Nanoscale particles prepared using the microemulsion technique with biodegradable and biocompatible lipid (stearic acid), surfactant (polyethylene-polypropylene glycol) and co-surfactant (polyoxyethylene20 sorbitanmonooleate). The prepared nanoscale solid lipid particles, particle size distribution, polydispersity index, zeta potential, entrapment efficiency, drug loading and drug content were characterized. The fabricated particles surface morphology was examined by transmission electron microscope. In-vitro release of Rasagiline mesylate loaded nanoscale solid lipid particles was studied using conical flask method. Release kinetics of Rasagiline mesylate from nanoscale solid lipid particles were studied using mathematical models.Results: The resulting Rasagiline mesylate loaded nanoscale solid lipid particles were successfully prepared with optimum particle size distribution, polydispersity index, zeta potential, entrapment efficiency, drug loading and drug content. Statistically significant differences were found among the drug release profile from RMSLN-I and RMSLN-II. Applying kinetic mathematical models, the mechanism of Rasagiline mesylate loaded nanoscale solid lipid particles release from the two formulations were found to be followed higuchi model, as the plots showed high linearity, with a correlation coefficient (R2) value of 0.98 or more. The ‘n’ value of korsmeyer-Peppas model lies below 0.5 and the mechanism controlling the drug release was Fickian diffusion.Conclusion: The prepared Rasagiline mesylate loaded nanoscale solid lipid particles controlling the drug delivery through diffusion dominated mechanism.Â
