Solubility 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 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 کاملEnhancement of Solubility of Poorly Water Soluble Drugs Diclofenac Sodium by Mixed Solvency Approach
Enhancement of solubility is one of the difficult tasks which become challenges in formulation development of orally administered drug with poor aqueous solubility. Poor water solubility of drugs often causes significant problems in producing formulations of sufficiently high bioavailability, preventing effective use of the drugs. 'Mixed-solvency ' concept is the phenomenon to increase the solu...
متن کاملSolid Dispersion as an Eminent Strategic Approach in Solubility Enhancement of Poorly Soluble Drugs
The solubility behavior of drugs remains one of the most challenging aspects in the formulation development. Although there was a great interest in solid dispersion systems during the past four decades to increase solubility by improving dissolution rate and bioavailability of poorly soluble drugs; there commercial use has been very limited, primarily because of manufacturing difficulties and v...
متن کاملA New Crystal Engineering Technique for Dissolution Enhancement of Poorly Soluble Drugs Combining Quasi-emulsion and Crystallo-co Agglomeration Methods
A target of best dissolution improvement of poorly soluble drugs is a necessity for the success of formulation in industry. The present work describes the preparation, optimization, and evaluation of a new spherical agglomeration technique for glimepiride as a model of poorly soluble drugs. It involved the emulsification of a drug solution containing a dispersed carrier that tailors the crystal...
