PREPARATION, CHARACTERIZATION AND EVALUATION OF NEBIVOLOL LOADED CHITOSAN NANOPARTICLES
Nebivolol (NEB) is an antihypertensive drug with poor oral bioavailability (12%) in humans due to extensive first pass hepatic metabolism. Present work is an attempt to improve oral bioavailability of nebivolol by incorporating it with biodegradable polymer chitosan and preparing its nanoparticles. The results indicated stable nanoperticles with the value of ZP to be +36.4 mV Â± 2 mV, the small particle size of 79.23 Â± 45 nm and high entrapment efficiency of 72.56%. The in vitro release study revealed sustained release of drug for 72 h with 71.24% cumulative drug release. The promising results from the study revealed the applicability of chitosan in the formulation of NEB loaded CNPs.
