Abstract : The most challenging task in drug development is enhancement of solubility, dissolution rate, and bioavailability of drug. Low aqueous solubility is the major problem encountered with formulation development of new chemical entities as well as for the generic development. Drug to be absorbed should be in solution form at the site of absorption. Absorption of orally administered drugs will take place only when they show fair solubility in gastric medium and such drugs show good bioavailability. Solubility and dissolution properties of drugs play an important role in the process of formulation and development. Major challenge for formulation scientist is the solubility problem which can be solved by different technological approaches during the pharmaceutical product development work. This review gives detailed information about various technologies used for enhancing solubility and dissolution of poorly soluble drugs, including nanotechnology methods for enhancing solubility to reduce the percentage of poorly soluble drug candidates eliminated from the development. Selection of this solubility enhancing method mainly depends on drug property, site of absorption and dosage form characteristics.
