Development of donepezil hydrochloride-loaded PLGA-based nanoparticles for Alzheimer's disease treatment.

ABSTRACT: In recent years, nanoparticle (NP) systems have demonstrated significant promise in pharmaceutical applications. This study focused on the development of donepezil hydrochloride-loaded PLGA-NPs, prepared using the 'Double Emulsion Solvent Evaporation' method. The impact of varying concentrations of polyvinyl alcohol-(PVA) in the aqueous phase and sonication time on NP characteristics was comprehensively examined. Results showed that increasing PVA concentration and sonication time resulted in a reduction in NP size, with an optimal formulation (I-DNP) achieving a particle size of 136.37 nm ± 0.93 and a PDI of 0.122 ± 0.011, indicating uniformity. The zeta potential was measured at - 24.17mV ± 1.21, confirming the electrostatic stability of the formulation, essential for long-term stability
