Abstract

<abstract> <title>Abstract</title> <p> <italic>Context</italic>: This study presents novel self-nanoemulsifying drug delivery system potential of oral delivering which leads poorly aqueous soluble drug glimepiride.</p> <p> <italic>Objective</italic>: The objective of this study was to prepare solid self-nanoemulsifying drug delivery system (S-SNEDDS) for the improved oral delivery of glimepiride and to evaluate its therapeutic efficacy in albino rabbits.</p> <p> <italic>Results and discussion</italic>: The droplet size analyses revealed a droplet size of less than 200 nm. The solid state characterization of S-SNEDDS by scanning electron microscopy (SEM), X-ray powder diffraction and differential scanning calorimetry (DSC) revealed the absence of crystalline glimepiride in the S-SNEDDS. The <italic>in vitro</italic> dissolution studies revealed that the significant improvement in glimepiride release characteristics. The effect of S-SNEDDS on therapeutic efficacy of glimepride was assessed in albino rabbits by monitoring blood glucose levels and compared with free drug suspension, L-SNEDDS. The S-SNEDDS showed significant (<italic>p</italic> &lt; 0.05) increase in <italic>in vitro</italic> drug release and therapeutic efficacy as compared with free drug.</p> <p> <italic>Conclusion</italic>: This study demonstrated that S-SNEDDS is a promising novel drug delivery system of glimepride to enhance oral delivery.</p> </abstract>
