Febuxostat (FXT), used for treating gout, is poorly soluble and is susceptible to enzymatic degradation when administered as tablets. The current study aims to formulate, optimize and develop a stable Liquid selfnanoemulsifying drug delivery system (L-SNEDDS) and Solid SNEDDS to improve solubility, resulting in enhanced bioavailability and further to formulate Self-Nano emulsifying Osmotic Pump Tablets (SNEOPT) for controlled drug release. A ternary plot was constructed with Capmul MCM (oil phase), Tween 80 (surfactant), and PEG 400 (co-surfactant). Further optimization was done by D-Optimal design. Optimized L-SNEDDS (F8) was then converted to S-SNEDDS by the adsorption method. Aerosil 200 was used as an adsorbent. The L-SNEDDS and S-SNEDDS were characterized and evaluated. The particle size of the optimized batch was 97.25 nm (L-SNEDDS) and 155.2 nm (S-SNEDDS). In-vitro dissolution studies showed>75% release in pH 1.2 HCl buffer and >80% in phosphate buffer pH 7.4 in 1 hour. SEM (Scanning electron microscopy) studies indicated spherical particle morphology. SNEOPT was prepared by direct compression (with NaCl as the osmogent). In-vitro release from SNEOPT showed zero-order drug release kinetics. The developed formulation was found to be superior to pure FXT with enhanced solubility, which signifies that a lipidic system is an efficacious drug delivery system for treating gout.
