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 کاملHydrotropic solubilization of poorly water-soluble drugs.
The solubilizing ability of two aromatic hydrotropes, N,N-diethylnicotinamide (DENA) and N,N-dimethylbenzamide (DMBA), was investigated using a set of 13 poorly soluble, structurally diverse drugs. The number of aromatic rings in the solute molecule has a very strong effect on the solubility enhancement produced by either hydrotrope. However, although solubility enhancements in the order of 100...
متن کاملEffect of hydrotalcite-like compounds on the aqueous solubility of some poorly water-soluble drugs.
A new approach of improving drug dissolution properties is described. This method exploits the property of a carrier owing to the hydrotalcite-type anionic clays (HTlc). HTlc is an inorganic layered solid that lodges anionic compounds among its layers. As HTlc dissolves at acidic pH values (pH < 4), the anions intercalated among the layers are promptly released in the medium. In this article so...
