Abstract
Solubility of drug candidate plays a vital role in selection of lead compound in early stage of drug development and discovery. Biopharmaceutical classification system distributes the drug candidate into different bins depending on the solubility and permeability. Two type of solubility determined at different stages of drug discovery, kinetic solubility and thermodynamic solubility. It is useful in deciding development plan and option of formulation development and to confirm result obtained from kinetic solubility data. Different problem encounter while determining the solubility, most of characteristics usually pH dependent, such as multiple and often overlapping ionization, complexation, aggregation, micelle formation, and “common ion” effect, incubation time, adsorption to micro porous filters, plastic or glass surfaces, polymorph interconversion. Above parameter should be considered while determining solubility. Different method available for measurement of the different solubility, conventional shake flask method now a day’s replaced by the high throughout solubility assay technique which considerably reduces the incubation time increased accuracy of result. Solubility determination can be done by ultraviolet absorption, nephlometry, Nuclear magnetic resonance and Potentiometric in drug discovery. The present review attempts to give a brief account of solubility and it’s importance, process of solubilisation, problems that occur while determining solubility, different types of solubility and there application, parameter to be considered while measuring solubility, different method to measure solubility, application in drug discovery in development, recent advances in solubility measurement.
