Development and Evaluation of Liquid and Solid Self-Emulsifying Drug Delivery Systems for Atorvastatin.
The objective of this work was to design and characterize liquid and solid self-emulsifying drug delivery systems (SEDDS) for poorly soluble atorvastatin. To optimize the composition of liquid atorvastatin-SEDDS, solubility tests, pseudoternary phase diagrams, emulsification studies and other in vitro examinations (thermodynamic stability, droplet size and zeta potential analysis) were performe...
متن کاملDevelopment of Solid Self Emulsifying Drug Delivery Systems Containing Efavirenz: in Vitro and in Vivo Evaluation
Efavirenz is a drug with an absorption window. Its oral bioavailability is 40-50%. The aim of this work was to formulate solid self-emulsifying drug delivery system to improve the solubility and bioavailability of efavirenz. Solubility of Efavirenz was determined in various vehicles like oils, surfactants and co surfactants. Which, upon dilution with aqueous media, spontaneously form fine oil i...
متن کاملDesign, Development and In Vitro Characterization of Self Emulsifying Drug Delivery System for Irbesartan
The objectives of present investigations were to optimize concentration of oil, surfactant and cosurfactant by pseudoternary phase diagrams and to develop a stable formulation of self emulsifying drug delivery system (SEDDS) in order to enhance the dissolution rate of poorly soluble Irbesartan (IBS) by SEDDS. Pseudoternary phase diagrams were constructed to identify the self emulsifying region....
متن کاملSystematic Development of Self-Emulsifying Drug Delivery Systems of Atorvastatin with Improved Bioavailability Potential
The aim of this study was to prepare and characterize a self-emulsifying drug delivery system (SEDDS) with a high drug load of poorly water-soluble atorvastatin for the enhancement of dissolution and oral bioavailability. Solubility of atorvastatin in oil, surfactant, and cosurfactant was determined. Pseudo-ternary phase diagrams were constructed by the aqueous titration method, and formulation...
متن کاملDevelopment of solid self-emulsifying drug delivery systems: preparation techniques and dosage forms.
Approximately 40% of new chemical entities exhibit poor aqueous solubility and present a major challenge to modern drug delivery system, because of their low bioavailability. Self-emulsifying drug delivery systems (SEDDS) are usually used to improve the bioavailability of hydrophobic drugs. Conventional SEDDS, however, are mostly prepared in a liquid form, which can produce some disadvantages. ...
