Mimosa pudica mucilage nanoparticles of losartan potassium: Characterization and pharmacodynamics evaluation

The current research was to develop nanoparticles based on Mimosa pudica mucilage (MPM) that could encapsulate losartan potassium (LP). Nanoparticles (NPs) produced through ionic-gelation method; the polymerization of the mucilage carried out using calcium chloride as cross-linking agent. The MPMLP-NPs demonstrated vastly enhanced pharmaceutical characteristics, presented discrete surface with spherical shape of 198.4-264.6 nm with PDI ranging 0.326-0.461 and entrapment efficiency was in the range of 80.65 ± 0.82-90.79 ± 0.96%. FTIR and DSC indicated the stability of drug during the formulation of nanoparticles. An acute oral toxicity investigation found no significant alterations in behavior and histopathology criteria. The MPMLP-NPs formulation revealed the better rates and sustained effect as assessed with the commercial product. Moreover, low dose of MPMLP-NPs showed similar anti-hypertensive effect as assessed with the marketed tablet.
