Self-microemulsifying drug delivery system (SMEDDS) of lovastatin was aimed at overcoming the problems of poor solubility and bioavailability. The formulation strategy included selection of oil phase based on saturated solubility studies and surfactant and co-surfactant screening on the basis of their emulsification ability. Ternary phase diagrams were constructed to identify the self-emulsifyi...

To assess the comparative bioavailability of two cyclosporine capsule products with different pharmaceutical formulation an open randomized two-period cross over study was conducted in 24 healthy volunteers. Our results, obtained from cyclosporine HPLC determination onto the whole blood samples collected, show that the test cyclosporine non-SMEDDS formulation was not bioequivalent cyclosporine ...

Olmesartan medoxomil (OLM) is an angiotensin II receptor blocker (ARB) antihypertensive agent administered orally that has absolute bioavailability of only 26% due to the poor aqueous solubility (7.75 μg/ml). The aim of the present investigation was to develop a self-microemulsifying drug delivery system (SMEDDS) to enhance the oral absorption of OLM. The solubility of OLM in various oils, surf...

In this study, various formulations of solidified carvedilol-loaded SMEDDS with high loading (up to 67% w/w) were produced the spray drying process using porous silica-based carriers. The yield was improved higher atomization gas flow rate during and prolonged mixing time dispersion liquid solid carriers prior process. Depending on choice carrier SMEDDS:carrier ratio in SMEDDS, different drug l...

The study was aimed at developing a self-microemulsifying drug delivery system (SMEDDS) of Ibuprofen for investigating its intestinal transport behavior using the single-pass intestinal perfusion (SPIP) method in rat. Methods. Ibuprofen loaded SMEDDS (ISMEDDS) was developed and was characterized. The permeability behavior of Ibuprofen over three different concentrations (20, 30, and 40 µg/mL) w...

Insulin resistance is caused by the inability of target tissues to respond to insulin. Bay leaf (Eugenia polyantha Wight) extract has been used for the treatment of insulin-resistant type-2 diabetes mellitus (IRDM), but it has low solubility and bioavailability. To overcome these problems, chloroform extract of bay leaves was formulated into a self-microemulsifying drug delivery system (SMEDDS)...

The clinical application of sirolimus (SRL) as an immunosuppressive agent is largely hampered by its narrow therapeutic range. This study focused on developing SRL tablets with a sustained release profile for better safety. SRL was highly water insoluble and its solubility has been efficiently enhanced by preparing self-microemulsifying drug delivery system (SMEDDS). The SRL-SMEDDS was physical...

A variety of nanoscale delivery systems have been shown to enhance the oral absorption of poorly water-soluble and poorly permeable drugs. However, the performance of these systems has seldom been evaluated simultaneously. The aim of this study was to compare the bioavailability enhancement effect of lipid-based nanocarriers with poly(lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) to highl...

Atorvastatin is a BCS class II lipid lowering agent. It is insoluble in aqueous solution of pH 4 and below; it is very slightly soluble in water and pH 7.4 phosphate buffer. In the present investigation an attempt has been made to enhance solubility and dissolution of poorly soluble drug by formulating self microemulsifying drug delivery system (SMEDDS). The solubility of atorvastatin in indivi...

The purpose of this research is to design and formulate the Self-micro emulsifying drug delivery system (SMEDDS) poorly water-soluble Sertraline Hydrochloride (SRT). SRT commonly used selective serotonin reuptake inhibitor for management a number depressive disorders. Its applicability limited because extensive metabolism poor oral bioavailability 44 %. Solubility in different vehicles determin...
