Overcoming the dissolution rate, gastrointestinal permeability and oral bioavailability of glimepiride and simvastatin co-delivered in the form of nanosuspension and solid self-nanoemulsifying drug delivery system: A comparative study
Abstract Simvastatin (SIM) and glimepiride (GLM) were co-formulated into nanosuspensions and self-nanoemulsifying drug delivery systems (SNEDDS) to improve their dissolution rate and oral bioavailability. Nanosuspension was prepared by liquid anti-solvent precipitation method, involving supersaturation of a solution by mixing the drug solution in an antisolvent. Liquid SNEDDS were prepared by loading drugs into an isotropic mixture of Capmul MCM, Labrafil M1944CS, Tween-80 and Transcutol P. Both formulations were solidified using spray drying. Enhancement in dissolution rate by 6.4 folds and 4.45 folds was observed for GLM and SIM respectively by preparing their nano-formulations. Drugs’ permeability was also enhanced by loading them into nano-formulations. The pharmacokinetic studies were conducted on rats which revealed increase in oral bioavailability by 6.69- and 4.22-folds for GLM and 1.76- and 2.68-folds for SIM respectively for nanosuspension and solid SNEDDS than their unprocessed forms. Both dissolution rate and oral bioavailability of SIM and GLM got significantly improved through S-SNEDDS and nanosuspension. However, performance of nanosuspension was found better than SNEDDS in terms of dissolution rate and oral bioavailability.

Abstract Fisetin (FS) was reported to have various pharmacological activities. But due to its lower aqueous solubility and oral bioavailability, it is not in much use. As solubility and bioavailability plays and important role in the pharmacological activity, in this research work we tried to improve the oral bioavailability of fisetin. In this research work, we developed self-nanoemulsifying drug delivery system (SNEDDS) of fisetin. Developed SNEDDS were subjected for pharmacokinetic and pharma...

Abstract Objective Lipid abnormalities beyond elevated low-density lipoprotein (LDL) cholesterol contribute to increased risk of atherosclerotic cardiovascular disease (ASCVD) in type 2 diabetes. Methods We searched for English language randomized clinical trials of lipid-lowering therapies primarily since 2012 that included patients with diabetes. Results Diet and lifestyle advice are always a starting point for ASCVD prevention in diabetes. After almost 30 years of widespread clinical use in d...

Abstract Fisetin is a plant derived flavonoid that possesses anti-cancer, anti-oxidant and anti-Parkinson's activities. However, due to its lipophilicity it suffers from dissolution rate limited oral bioavailability that reduces its therapeutic efficacy. In order to overcome this issue self-nanoemulsifying drug delivery system (SNEDDS) of fisetin were formulated and characterized for droplet size, shape, zeta potential, cell viability, dissolution and permeability studies. Prepared SNEDDS (1.2 m...

Abstract Advantage of spray drying technique over the conventional surface adsorption technique for co-formulation of solid SNEDDS (S-SNEDDS) of curcumin (CRM) and duloxetine (DXH) is discussed. Liquid SNEDDS were prepared using castor oil (20% w/w), Tween-80 (40% w/w) and Transcutol® P (40% w/w) as oil, surfactant and co-surfactants containing both CRM and DXH. S-SNEDDS were formulated by adsorption of liquid SNEDDS onto porous hydrophilic and hydrophobic carriers through spray drying and surfa...

AbstractDevelopment of self-nanoemulsifying drug delivery systems (SNEDDS) of glimepiride is reported with the aim to achieve its oral delivery. Lauroglycol FCC, Tween-80, and ethanol were used as oil, surfactant, and co-surfactant, respectively as independent variables. The optimized composition of SNEDDS formulation (F1) was 10% v/v Lauroglycol FCC, 45% v/v Tween 80, 45% v/v ethanol, and 0.005% w/v glimepiride. Further, the optimized liquid SNEDDS were solidified through spray drying using var...

Box-Behnken design (BBD) was adopted to develop and optimize the composition of SNEDDS. Oleoyl polyoxyl-6 glycerides (A), Tween 80 (B), and diethylene glycol monoethyl ether (C) were used as oil, surfactant and co-surfactant, respectively as independent variables. The effect of variation in their composition was observed on the mean droplet siz...

The success story of liposomes in the treatment of systemic infectious diseases and various carcinomas lead the scientists to the innovation of elastic vesicles to achieve similar success through transdermal route. In this direction, ethosomes and transfersomes were developed with the objective to design the vesicles that could pass through the skin. Both these delivery systems have proven themselves as promising carriers to transport drugs across skin. Both these elastic nanocarriers offer uniq...

Abstract In the current study, a novel self-nanoemulsifying drug delivery system (SNEDDS) was developed in order to improve the oral bioavailability of delafloxacin (DLF). Various oils, surfactants and co-surfactants were screened by solubility studies. Based on solubilization, potential of DLF in various vehicles, LauroglycolTM-90 (oil), Tween® 80 (surfactant) and Transcutol®-HP (co-surfactant) were selected for the development of DLF loaded SNEDDS (DLF-SNEDDS). Four formulae of DLF loaded SNED...
Albendazolum (ABZ) is a BCS class II drug. It has challenging biopharmaceutical properties, which include poor solubility and dissolution rate. These properties have laid the ground for developing a supersaturated self-nanoemulsifying drug delivery system (S-SNEDDS) to form oil-in-water nanoemulsion in situ to improve the oral bioavailability of ABZ. Based on the ABZ solubility, emulsifying ability, and stability after dispersion in an aqueous phase, an optimal self-nanoemulsifying drug delivery...
