Self-emulsifying drug delivery systems (SEDDS) have the potential to enhance bioavailability and therapeutic impact of active ingredients that are poorly water-soluble, low pemeability unstable. The ingredient, oil, surfactant, co-surfactant and/or co-solvent main elements SEDDS. Supersaturable SEDDS been developed increase efficiency ingredient loading by incorporating precipitation inhibitors...

Many drug substances exhibit low solubility in water, which results in their poor bioavailability. Among ophthalmic preparations, oil solutions, suspensions and ointments are formulations prepared for such compounds. Promising modern drug carries are self-emulsifying drug delivery systems (SEDDS) which are isotropic mixtures of oils and surfactants. Due to presence of surfactants improved solub...

The objective of the present work was to formulate a self-emulsifying drug delivery system (SEDDS) for simvastatin, which is widely used in the treatment of hypercholesterolemia and dyslipidemia as an adjunct to diet. Simvastatin SEDDS were formulated using a 1:1 (V/V) mixture of diesters of caprylic/capric acids and polyglycolyzed glycerides with varying concentrations of polyoxy castor oil an...

Solidification of lipid formulations using adsorbents is a recent technique attracting great interest due to its favourable properties including flexibility in dose division, reduction of intra-subject and inter-subject variability, improvement in efficacy/safety profile and enhancement of physical/ chemical stability. The current study aims to convert liquid self-emulsifying/nanoemulsifying dr...

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....

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...

Oral route is the easiest and most convenient route for drug administration. Oral drug delivery systems being the most cost-effective and leads the worldwide drug delivery market. The major problem in oral drug formulations is low and erratic bioavailability, which mainly results from poor aqueous solubility. This may lead to high interand intra subject variability, lack of dose proportionality...

Self-emulsifying drug delivery systems (SEDDS) were prepared by dissolving Cremophor EL, Tween 20, Tween 80 and Span 80 (1% or 5%) in oils (Miglyol 812 or castor oil). Solubilities of three ophthalmic drugs, namely aciclovir, hydrocortisone and indomethacin were determined in these systems. In addition, the effect of a small amount of water (0.5% and 2%) on solubilization properties of the syst...

Self-emulsifying drug delivery systems (SEDDS) are usually used to improve the bioavailability of hydrophobic drugs. 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. From time to time many workers have claimed various rational applications of Self-emulsifying formulation...
