Systematic approach for the formulation and optimization of atorvastatin loaded solid lipid NANOAPARTICLES using response surface methodology.

Atorvastatin is a lipid lowering agent with poor oral bioavailability (12%) because of poor solubility and extensive first pass hepatic metabolism. In order to overcome these issues, atorvastatin loaded solid lipid nanoparticles (ATOR-SLNs) were prepared by using glyceryl tripalmitate as lipid carrier, poloxamer 407 as surfactant and soya lecithin as emulsifier. The purpose of this work was to optimize the formulation with the application of response surface methodology to improve the physicochemical properties.

Assessment of erythropoietin for treatment of anemia in chronic kidney failure- ESRD patients.

Background And Objective: Currently there is an inadequate data regarding effective management of anemia in chronic kidney disease (CKD) patients who are on dialysis. In CKD patients' anemia mainly develops from decreased renal synthesis of erythropoietin (EPO) and iron deficiency. Our current study focused to effective management of anemia in CKD patients'.

Synthesis and evaluation of MePEG-PCL diblock copolymers: surface properties and controlled release behavior.

The amphiphilic block copolymers are composed of various combinations of hydrophilic and hydrophobic block unimers. The variation in unimer ratio alters the surface as well as micelle-forming properties of the block copolymers. These nanoscopic micelles have the ability to encapsulate hydrophobic compounds and act as potential drug carrier.

Preparation and characterization of nebivolol nanoparticles using Eudragit® RS100.

Nebivolol, a beta-blocker, has been widely used for the treatment of hypertension and cardiovascular diseases; but has drawbacks like poor solubility and bioavailability requiring frequent dosing. The present study attempts to overcome these issues through nanoparticulate delivery system using widely used carrier Eudragit(®) RS100. The solvent evaporation (single emulsion) technique was used for developing nanoparticles.

Preparation and evaluation of a new erythromycin derivative -- erythromycin taurate.

Erythromycin taurate, a new derivative of erythromycin, was prepared by reacting erythromycin base with tauric acid and its physico-chemical and biological properties were evaluated. The derivative has reasonably good solubility in organic solvents. The partition coefficient values in chloroform/water 1.
