AN OVERVIEW ON SOLUBILITY ENHANCEMENT TECHNIQUES FOR POORLY SOLUBLE DRUGS AND SOLID DISPERSION AS AN EMINENT STRATEGIC APPROACH
AbstractSolubility is an important parameter to achieve desired concentration of drug in systemic circulation for pharmacological response to be shown. Among all newly discovered chemical entities most of the drugs are lipophillic and fail to reach market due to their poor water solubility. The solubility behavior remains one of the most challenging aspect informational development. Hence various techniques are used for the improvement of solubility of poorly water soluble drugs which include micronization, chemical modification, pH adjustment, solid dispersion, complexation, co-solvency micellar solubilization, hydrotrophy etc. Of all these approaches solid dispersion have attracted tremendous interest as an efficient means of improving the dissolution rate and hence the bioavailability to arrange of hydrophobic drugs. This article reviews the various preparation techniques and types of solid dispersion based on molecular arrangement. Finally some of the practical aspects have also been considered for the preparation of dispersions.
