Abstract
To prepare nanostructured lipid carriers (NLCs) loaded with asenapine maleate (ASPM) to increase its oral bioavailability by intestinal lymphatic uptake. ASPM-NLCs were prepared by ultrasound dispersion technique, by adopting Design of Experiment approach, and characterized. The optimized formulation exhibited good physicochemical parameters. Differential scanning calorimetry and x-ray diffraction studies indicated the amorphized nature of ASPM in lipid matrix. In vitro drug release study indicated the sustained release of drug from NLCs. ASPM-NLCs showed greater permeability across Caco2 cells and everted rat ileum. ASPM-NLCs showed greater cellular uptake, superior preclinical oral bioavailability and higher efficacy in reducing the L-DOPA-carbidopa-induced locomotor count compared with plain drug. ASPM-NLCs were successfully developed that showed enhanced performance both in vitro and in vivo.
