Context: This study presents novel self-nanoemulsifying drug delivery system potential of oral delivering which leads poorly aqueous soluble drug glimepiride.
Objective: 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.
Results And Discussion: 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 in vitro 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 (p < 0.05) increase in in vitro drug release and therapeutic efficacy as compared with free drug.
Conclusion: This study demonstrated that S-SNEDDS is a promising novel drug delivery system of glimepride to enhance oral delivery.

The ability to predict the absorption of exenatide (Ex), a GLP-1 analogue, after oral dosing to rats in self-nanoemulsifying drug delivery systems (SNEDDS), using in vitro methods, was assessed. Ex was complexed with soybean phosphatidylcholine (SPC) prior to loading into SNEDDS. A design of experiments (DoE) approach was employed to develop SNEDDS incorporating medium-chain triglycerides (MCT), medium-chain mono- and diglycerides (MGDG), Kolliphor® RH40, and monoacyl phosphatidylcholine.

Introduction: Rhein, a natural bioactive lipophilic compound with numerous pharmacological activities, faces limitations in clinical application due to poor aqueous solubility and low bioavailability. Thus, this study aimed to develop a rhein-loaded self-nano emulsifying drug delivery system (RL-SNEDDS) to improve solubility and bioavailability.
Methods: The RL-SNEDDS was prepared by aqueous titration method with eucalyptus oil (oil phase), tween 80 (surfactant), and PEG 400 (co-surfactant) and optimization was performed by 3 factorial design.

Flurbiprofen (FBP) is poorly water-soluble BCS class II drug with anti-inflammatory and analgesic effects, used to treat arthritis and degenerative joint diseases. This study was aimed to develop SNEDDS loaded with FBP. Six SNEDDS using two oils olive oil (F, F, F) and castor oil (F, F, F) with three different Smix ratios consisting of Tween 20 and PEG 400 (1:1, 1:2, 2:1) were prepared and characterized.

Purpose: This study aimed to develop a solid self-nanoemulsifying drug delivery system (SNEDDS) and surface-coated microspheres to improve the oral bioavailability of niclosamide.
Methods: A solubility screening study showed that liquid SNEDDS, prepared using an optimized volume ratio of corn oil, Cremophor RH40, and Tween 80 (20:24:56), formed nanoemulsions with the smallest droplet size. Niclosamide was incorporated into this liquid SNEDDS and spray-dried with calcium silicate to produce solid SNEDDS.
