Abstract:

This study aimed to consolidate rupatadine fumarate (RF) into nanoparticles to control its release. Ten RF nanoparticles were developed by nanoprecipitation using poly (lactic-co-glycolic acid) (PLGA) , polyvinyl alcohol (PVA), and Poloxamer 407 (Kolliphor P 407) in different percentages. A valid reverse-phase HPLC method was developed to assess RF in the formulated nanoparticles. The RF nanoparticles were tested chemically and morphologically. RF nanoparticles containing PLGA and PVA and Kolliphor P 407 have zeta potentials ranging from -24.4 mV±0.24 to -26.7 mV±0.05, higher than other formulations, and their release profiles were optimised. The formula (RPX3) had the best zeta potential (-26.7 mV±0.05), released about 86% of RF after 8 h and extended for 24 h. In summary, the formulation (RPX3), including 2:10:3:1.5 ratios of the drug PLGA: PVA: Kolliphor P 407 was the optimised RF-loaded nanoparticles formulation.
