Functions of Lipids for Enhancement of Oral Bioavailability of Poorly Water-Soluble Drugs
Lipid-based formulations encompass a diverse group of formulations with very different physical appearance, ranging from simple triglyceride vehicles to more sophisticated formulations such as self-emulsifying drug delivery systems (SEDDS). Lipid-based drug delivery systems may contain a broad range of oils, surfactants, and co-solvents. They represent one of the most popular approaches to over...
متن کاملSolubility Enhancement of Poorly Water Soluble Drugs: a Review
Among all newly discovered chemical entities about 40% drugs are lipophillic and fail to reach market due to their poor water solubility. Drug with poor water solubility cause slow dissolution rates, generally show erratic and incomplete absorption leading to low bioavailability when administered orally. Aqueous solubility of any therapeutically active substance is a key property, as it governs...
متن کاملSolubility Enhancement of Poorly Water Soluble Drugs by Solid Dispersion
Solid dispersions have been employed to enhance the dissolution rates of poorly water-soluble drugs. Many approaches have been investigated for the preparation of solid dispersions. This paper reports the various solubility enhancement strategies in solid dispersion. The approaches described are fusion (melting), solvent evaporation, lyophilization (freeze drying), melt agglomeration process, e...
متن کاملEnhancement of gastrointestinal absorption of poorly water soluble drugs via lipid based systems.
Development of knowledge on lipids has attracted the scientific community for the effective utilization of the natural and synthetic lipids. Bioavailability of poorly water soluble drugs from gastrointestinal tract (GIT) can be enhanced by formulating the drugs in lipid based formulations. This formulation can increase the dissolution of poorly water soluble drugs, and facilitates the formation...

Submit Manuscript | http://medcraveonline.com J Anal Pharm Res 2015, 1(1): 00001 in terms of dissolution but the non-traditional formulation approaches can lead to a significant increase in dissolution and solubility particularly required for drugs applied in medium to higher dosages [3]. Such dosages’ requirements go along with the necessity to evaluate other formulation technologies for enhan...
