Celecoxib, a diaryl substituted pyrazole, is practically insoluble in water which precludes its use in parenteral and liquid dosage forms. This study explores the solubility enhancement of celecoxib using hydrotropy and cosolvency solubilization approaches. The equilibrium solubility studies were performed using hydrotropes piperazine, sodium citrate, and urea and cosolvents PEG 200, PEG 400, P...

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...

glucosyl-ƒ¿-CD (G-ƒ¿-CD), 6-O-ƒ¿-D-glucosyl-ƒÀ-CD (G-ƒÀ-CD), and 6A,6D-di-O-ƒ¿-D-glucosyl-ƒÀ-CD (2G-ƒÀ-CD) with slightly soluble or insoluble drugs in aqueous solution and in the solid state was studied by the solubility method, ultraviolet spectroscopy, and differential scanning calorimetry. These glucosyl-CDs were capable of forming inclusion complexes with compounds which can form complexes ...

The drug candidates coming from combinatorial chemistry research and/or the drugs selected from biologically based high-throughput screening are quite often very lipophilic, as these drug candidates exert their pharmacological action at or in biological membranes or membrane-associated proteins. This challenges drug delivery institutions in industry or academia to develop carrier systems for th...

Introduction Although the capability of ingested lipids to enhance the bioavailability of poorly water-soluble drugs has been experimentally observed and established 1 , the phenomenon is not well understood and is unpredictable. Commercially, lipids could offer valuable opportunities for enabling oral drug delivery, as approximately 4070% of all new drug candidates have been estimated to have ...
