The objective of this study was to optimize and characterize an oridonin self-microemulsifying drug delivery system (SMEDDS) formulation. A central composite design (CCD) was used to investigate the influence of factors (oil percentage and surfactant to co-surfactant ratio (Sur/Co-s ratio)) on the responses including droplet size, polydispersity, equilibrium solubility and in situ intestine abs...

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...

The purposes of the present study were to develop a self-microemulsifying drug delivery system (SMEDDS) containing bortezomib, a proteasome inhibitor. The solubility of the drug was evaluated in 15 pharmaceutical excipients. Combinations of oils, surfactants and cosurfactants were screened by drawing pseudo-ternary phase diagrams. The system exhibiting the largest region of microemulsion was co...

The purpose of preparing Self microemulsifying drug delivery system in this work is to enhance the solubility and oral bioavailability of poorly water soluble drug, Glimepiride. SMEDDS are the isotropic mixture of surfactant, co-surfactant and oil incorporated with drug. In the aqueous media, gastro intestinal motility emulsification takes place. Glimepiride was undergone solubility studies in ...

Poor aqueous solubility and dissolution limit the oral bioavailability of Biopharmaceutics Classification System (BCS) class II drugs. In this study, we aimed to improve raloxifene hydrochloride (RLX), a BCS drug, using self-microemulsifying drug delivery system (SMEDDS). Based on solubilities RLX, Capryol 90, Tween 80/Labrasol ALF, polyethylene glycol 400 (PEG-400) were selected as oil, surfac...

Background: In the Biopharmaceutical Classification System (BCS), ibuprofen (IBU) belongs to Class II (poorly soluble, well-absorbed), which limits its therapeutic effectiveness due low bioavailability. Currently, self-microemulsifying drug delivery systems (SMEDDS) are used stabilize compounds and enhance solubility absorption of poorly soluble absorbable drugs. Therefore, objective this study...

Oral route is the easiest and most convenient route of drug administration, being non invasive and cost effective, thereby leading worldwide drug delivery market. But major problem encountered in oral formulations (as estimated more than 50 % of oral formulations are found to be poorly aqueous soluble), is low bioavailability, giving rise to further problems like, high inter and intra subject v...

Abstract
 The present investigation aimed to formulate a liquid self-microemulsifying drug delivery system (SMEDDS) of tacrolimus enhance its oral bioavailability by improving dispersibility and dissolution rate. Four SMEDDS were prepared using maisine CC as oil phase, labrasol ALF surfactant transcutol HP co-surfactant based on the solubility studies in these components. phase behavior co...

BACKGROUND The objective of this study was to prepare, characterize, and evaluate a folate-modified self-microemulsifying drug delivery system (FSMEDDS) with the aim to improve the solubility of curcumin and its delivery to the colon, facilitating endocytosis of FSMEDDS mediated by folate receptors on colon cancer cells. METHODS Ternary phase diagrams were constructed in order to obtain the m...

INTRODUCTION Solubility is one of the important parameter to achieve desired concentration of drug in systemic circulation for pharmacological response. Poor aqueous solubility of lipophilic drugs creates problems in formulation as well as in oral administration. Various approaches have been developed to resolve poor aqueous solubility of lipophilic drugs. As oral route for drug administration ...
