    Objective: The objective of the present study was to formulate self-microemulsifying drug delivery system (SMEDDS) to enhance the oral bioavailability of losartan. Experimental: The solubility of losartan was determined in various vehicles, and pseudoternary phase diagrams were used to assess the micro-emulsification boundary. The losartan SMEDDS was prepared using Capmul MCM EP (oil), tween 80 (surfactant), and polyethylene glycol (PEG) 400 (cosurfactant). Results: The SMEDDS was tested for microemulsifying properties, and the resultant microemulsions were evaluated for droplet size, zeta potential, transmission electron microscopy, and in vitro dissolution. The formulation development and screening were done on the basis of results obtained from phase diagrams and characteristics of resultant microemulsions. The selected formulation of Capmul MCM EP with surfactant and cosurfactant mixture (Smix) ratio of 1:1 (Tween-80: PEG-400) subjected to in vivo bioavailability study using rabbit. The results of drug release and oral bioavailability of losartan SMEDDS were compared with marketed formulation. The selected formulation enhanced the oral bioavailability of losartan by 1.49 folds than the marketed formulation.
