Abstract

Poor water solubility of the drug presents a great challenge for the formulation development and results in low oral bioavailability. The oral bioavailability of  Raloxifene HCl (RLX) is very  low (<2%) in human due to its poor solubility and extensive (>90%) first pass metabolism. To overcome these limitations, the present investigation deals with the development of Compritol 888 ATO based RLX-loaded solid lipid nanoparticles (SLNs) using oil in water microemulsion method. Drug-excipients compatibility was confirmed through FTIR spectroscopy, Differential scanning calorimetry. A total seventeen formulations (SLN1-SLN17) were developed as per the 3 level 3 factor Box–Bhenken design. The model used for the analysis were statistically analysed using ANOVA and the goodness of fit was evaluated using diagnostic plots. As per the response-surface plots, the amount of lipid, poloxamer 407 and ultrasonication time has significant effect on the particle size and entrapment efficiency (%EE). As per the desirability function value (0.959) the optimized formulation has the size and EE of 169.32 nm and 92.85%.
