Definition

In understanding how a drug behaves once dosed to a body, a drug’s solubility in an aqueous media is a key parameter in controlling the subsequent in vivo levels [1]. Many solubility methods have been developed to provide in vitro solubility measurements. These methods expose a compound to a solvent for a period of time and then determine the concentration of the dissolved compound. For what is a relatively simple experiment to perform, there are numerous experimental factors that can affect a solubility measurement and, consequently, influence drug discovery decisions to varying extents.

The Importance of Solubility to a Drug

In the scenarios where a drug’s route of administration relies...
