Schizophrenia is severe chronic disabling brain disease affecting about 24 million people worldwide and 4 million people in India as WHO 2011 report. Asenapine maleate (ASN) is a novel psychopharmacologic agent recommended for treatment of Schizophrenia and Bipolar disorder. ASN suffers with the problems of poor aqueous solubility, very low oral bioavailability (1-2%) and high patient non-adherence. Therefore, objective of the present study was to prepare Nanostructured Lipid Carriers (NLCs) of Asenapine maleate to improve the bioavailability and enhance the uptake of ASN to the brain via intranasal route. Asenapine loaded NLCs (ASN-NLCs) were prepared by melt emulsification-high shear homogenization method. For preparation of NLCs, Glyceryl monostearate, Oleic acid and Tween 80 were used as solid lipid, liquid lipid and surfactant, respectively. ASN-NLCs were characterized for particle size, zeta potential, entrapment efficiency, in-vitro drug release study, XRD and DSC. Stability study was performed at 25?C/60% RH for three months. Further, pharmacodynamic studies (paw test and l-dopa induced locomotor activity test) were performed on rat model to evaluate the efficacy of formulation. ASNNLCs were successfully prepared and optimized with particle size below 200 nm, zeta potential -15.38?2.17 mV, EE 82?3.5% and more than 85% drug release in 24 h. The XRD and DSC analysis indicate that Asenapine was present in amorphous state in NLCs. The ASN-NLCs were stable over 3 month studies. In pharmacodynamic studies, significant increase (p<0.05) in antipsychotic potential was observed in ANS-NLCs as compared to pure drug. These results indicate that the NLCs are having a potential to deliver drug into the brain from the non-invasive intranasal route.
