Oral bioavailability is the major problem when a poorly water-soluble active agent is delivered via oral route. To overcome such problems, solid dispersion systems have been demonstrated in literature to enhance the dissolution property of poorly water-soluble drugs. In the present review, the important aspects to be considered during preparation of solid dispersion systems viz., properties of polymer and preparation techniques of solid dispersion which affect the dissolution rate are discussed. Formulation and evaluation techniques for solid dispersions have been described. The final section of article highlights the recent patents and studies related to solid dispersion systems.
