The aim of the present study was to prepare solid lipid nanoparticles (SLNs) for the oral delivery of frankincense and myrrh essential oils (FMO). Aqueous dispersions of SLNs were successfully prepared by a high-pressure homogenization method using Compritol 888 ATO as the solid lipid and soybean lecithin and Tween 80 as the surfactants. The properties of the SLNs such as particle size, zeta po...

the objective of research was to explore the suitability of lipids like compritol 888 ato and stearic acid as release retardant to develop sustained release (sr) tablets. the sr micromatrices of lipid (s) and glipizide were prepared (lm1- lm6) as intermediate product by fusion method and assessed for various pharmacotechnical properties. micromatrices were formulated as sr tablets (f1-f6) by di...

The effect of SLN incorporation on transdermal delivery and in vitro antiherpetic activity of Artemisia arborescens essential oil was investigated. Two different SLN formulations were prepared using the hot-pressure homogenization technique, Compritol 888 ATO as lipid, and Poloxamer 188 and Miranol Ultra C32 as surfactants. Formulations were examined for their stability for two years by monitor...

Valsartan is an antihypertensive drug with poor oral bioavailability ranging from 10-35% because of poor solubility, dissolution and most importantly, extensive first pass hepatic metabolism. The present study deals with the development and characterization of Valsartan-loaded solid lipid nanoparticles (VSLNs) to enhance the solubility, bypass the first pass hepatic metabolism, and enhance the ...

Raloxifene hydrochloride (RL-HCL) is an orally selective estrogen receptor modulator (SERM) with poor bioavailability of nearly 2% due to its poor aqueous solubility and extensive first pass metabolism. In order to improve the oral bioavailability of raloxifene, raloxifene loaded solid lipid nanoparticles (SLN) have been developed using Compritol 888 ATO as lipid carrier and Pluronic F68 as sur...

solid lipid nanoparticles of atovaquone (atq-sln) were prepared by high shearhomogenization method using tripalmitin, trilaurin, and compritol 888 ato as the lipidmatrices and phospholipon 90h, tween 80, and poloxamer 188 as the surfactants. optimizationof the formulations was conducted using 6 sets of 24 full-factorial design based on fourindependent variables that were the number of homogeniz...

Objective: Naftopidil (NAF) is a selective alpha1-adrenergic receptor antagonist with nearly 20% bioavailability due to poor aqueous solubility, permeability, and extensive first-pass metabolism. To improve the of NAF, solid lipid nanoparticles (SLN) NAF were prepared. Methods: SLNs prepared using solvent emulsification/evaporation method excipients Compritol 888 ATO Poloxamer 188. Formulation ...

The efficacy of rifabutin (RIFA) alone or in combination with atovaquone (ATO) was examined in vitro and in a murine model of acute toxoplasmosis. In vitro studies were performed with MRC5 fibroblast tissue cultures, with quantification of Toxoplasma growth by enzyme-linked immunosorbent assay. For in vivo studies, mice were acutely infected with 10(4) tachyzoites of the virulent RH strain and ...

Purpose: To study the effect of compritol ATO888 and kollidon SR blend on the release of chlorpheniramine maleate (CPM) from its matrix tablets prepared by direct compression. Methods: Different ratios of compritol and kollidon SR (containing 50 % matrix component) in 1:1, 1:2, 1:3 and 3:1 ratios were formulated using direct compression. The formulations were organoleptically tested and investi...

Etravirine is an antiviral belonging to biopharmaceutics classification system class IV due low aqueous solubility and poor permeability. In this study, augment the dissolution profile of etravirine, solid lipid nanoparticles have been formulated by utilizing mixture Compritol® 888 ATO Gelucire® 50/13 as lipids poloxamer 188 surfactant hot homogenization technique. Effect variables, ratio lipid...
