    Objective: The objective of this research work was to formulate, optimize, and evaluate a self-emulsifying drug delivery system (SEDDS) of simvastatin (SIM) by employing a systematic formulation strategy using response surface methodology, i.e., Box–Behnken design (BBD) and to acquire basic concepts that assist in the evolution of such systems more practicable. Methods: Screening of oils and surfactants was done on the basis of solubility studies and phase diagrams were constructed to define the upper and lower limit of oil and surfactant for formulation development. BBD was applied involving three variables (concentration of oil, concentration of surfactant, and mixing time) and two responses (emulsification time and percentage transmittance). This approach aided in predicting the effect of individual component on the responses with the help of response surface curves and to investigate the interactions between excipients and thus to discover the best formulation. Results: Run order 3 was selected which was further validated using optimization of data. Finally, formulation OF1 was optimized and characterized for particle size, polydispersity index (PDI), zeta potential, emulsification time, percentage transmittance and in vitro dissolution studies. For OF1, the value of particle size, PDI, zeta potential, emulsification time, and percentage transmittance was 162 nm, 0.194, −22.3 mV, 93 s, and 99.45%, respectively. In vitro release studies from optimized formulation, OF1, displayed highest drug release as compared to SIM API and marketed preparation, thus enhancing the dissolution. Conclusion: This study confirms that for emergence of a successful SEDDS with enhancement in dissolution of a BCS Class II drug for oral administration can be more relevant by employing experimental design.
