Objective To optimize the formulation and preparation technology of ketoprofen nanosuspensions. Method The ketoprofen nanosuspensions were prepared by precipitation and high pressure homogenization method and the optimized formulation was obtained by the single factor test method with particle size and its distribution as evaluating indexs. Result The particle size, polydispersity index and Zeta potential of the prepared ketoprofen nanosuspensions were 109.6 nm ,0. 297,-21.1 mV respectively. Conclusion The precipitation and high pressure homogenization technology employed to prepare ketoprofen nanosuspensions is feasible. This study provided potential for the new dosage form development of ketoprofen.
