Rosuvastatin is a lipid lowering agent, which has low solubility and low bioavailability of 20% with oral administration. Therefore the present study was undertaken to improve solubility and bioavailability of Rosuvastatin by formulating it into Nano structured lipid carriers (NLCs) by using stearic acid and Compritol ATO 888 as solid-lipid, Oleic acid as liquid-lipid and Poloxamer 188 as a sur...

The purpose of this investigation was to prepare a gastro retentive drug delivery system of famotidine tablets. Floating tablets of famotidine were prepared employing lipid solid dispersion spray drying technique with gelucire 50/13 and compritol 888 along with HPMC K100M, lactose, sodium bicarbonate and citric acid. The floating tablets were evaluated for uniformity of weight, hardness, friabi...

Metformin hydrochloride (MET) sustained-release solid dispersions (SD) were prepared by the solvent evaporation and closed melt method, using compritol 888 ATO as the polymer with five different drug-carrier ratios. Characterization of solid dispersion was carried out by Fourier Transform Infrared (FTIR) spectroscopy, ultraviolet (UV) spectroscopy, Differential scanning calorimetry (DSC), X-ray...

Novel solid lipid nanoparticles (SLNs) were developed to improve oral bioavailability of oxyresveratrol (OXY). The SLNs were prepared by a high speed homogenization technique, at an effective speed and time, using Compritol 888 ATO (5% w/w) as the solid lipid. The appropriate weight proportions (0.3% w/w) of OXY affected the physicochemical properties of blank SLNs. The effects of surfactant ty...

Solid lipid nanoparticles (SLN), nanostructured lipid carriers (NLC) and nanoemulsion (NE) of lornoxicam (LRX) were prepared for the treatment of painful and inflammatory conditions of the skin. Compritol® 888 ATO, Lanette® O and oleic acid were used as solid and liquid lipids. SLN, NLC and NE were found physically stable at various temperatures for 6 months. Case I diffusional drug release was...

Coenzyme Q10 (Q10) loaded solid lipid nanoparticles (SLN) were prepared by the high speed homogenization method and incorporated into Carbopol 974P hydrogels. Compritol 888 ATO (C888) was employed as the lipid base; Poloxamer 188 (P188) and Tween 80 (Tw80) were used as surfactant and co-surfactant. Optimum particle size with narrow distribution was obtained as 152.2 nm for blank and 142.4 nm fo...

PURPOSE Lycopene belongs to the carotenoids that shows good pharmacological properties including antioxidant, anti-inflammatory and anticancer. However, as a result of very low aqueous solubility, it has a limited systemic absorption, following oral administration. METHODS Here, we prepared a stable lycopene-loaded solid lipid nanoparticles using Precirol® ATO5, Compritol 888 ATO and myristic...

The ether lipid 1-O-octadecyl-2-O-methyl-rac-glycero-3-phosphocholine, edelfosine (ET-18-OCH(3)) is the prototype molecule of a promising class of antitumor drugs named alkyl-lysophospholipid analogues (ALPs) or antitumor ether lipids. This drug presents a very important drawback as can be the dose dependent haemolysis when administered intravenously. Lipid nanoparticles have been lately propos...

Solid lipid nanoparticles (SLNs) have been used for carrying different therapeutic agents because they improve absorption and bioavailability. The aim of the study was to prepare lipidic nanoparticles containing cyclosporine (CyA) by the emulsification-diffusion method and to study their physicochemical stability. Glyceryl behenate (Compritol(®) ATO 888) and lauroyl macrogolglycerides (Gelucire...
