it has been observed that most of the chemical entities have high lipophilicity and poor aqueous solubility, which result in poor bioavailability. in order to improve the bioavailability, the release behavior of such drugs should be improved. although there are numerous techniques to handle solubility related issue, but they are expensive due to involvement of complicated equipments, advanced m...

Water-insoluble materials containing amorphous solid dispersions (ASD) are an emerging category of drug carriers which can effectively improve dissolution kinetics and kinetic solubility of poorly soluble drugs. ASDs based on water-insoluble crosslinked hydrogels have unique features in contrast to those based on conventional water-soluble and water-insoluble carriers. For example, solid molecu...

       The formulation of hydrophobic drugs for oral drug delivery is challenging due to poor solubility, poor dissolution and poor wetting of these drugs. Consequently, the aim of this study was to improve the dissolution of a model poorly water soluble drug, ibuprofen. Microparticles containing ibuprofen were produced by spray drying and spray chilling technology in the absence/presence of a ...

INTRODUCTION Many drugs show bioavailability problems due to their low water solubility, slow dissolution rate, and instability in the gastrointestinal tract. Nimesulide is a non-steroidal anti-inflammatory, analgesic and antipyretic agent, chemically is N-(4 nitro-2-phenoxyphenyl) methane sulfonamide. It is poorly soluble in water and irregularly absorbed by gastrointestinal tract. Among the v...

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...
