Objective:To optimize the formula of ibuprofen slowly-released in situ gels and investigate the corrosion of gels and the release of the ibuprofen from the gels.Methods:The in situ gels were prepared by cold method.The effects of IBU-HP-β-CyD and sodium alginate on gelatination temperature(Tsol-gel) were investigated.The concentration of P407 and P188 were optimized by uniform design and the corrosion behavior of gels was studied by membraneless model.The fluid of the corrosion was quantitatively analyzed by HPLC.Results:The Tsol-gel was degraded with the increase of sodium alginate.The optimized concentration of P407/P188 was 19%/5%.The corrosion of gels and the release of the ibuprofen fitted zero-order kinetics.Conclusion:Uniform design is fit to optimize the concentration of P407 and P188.The gels meet the requirement of sustained-release preparation.
