The initial focus when ,screening, potential media is to start with those which are aqueous based, within the pH range of 1.2-6.8 at the recommended ionic strength (as per USP/EP). When assessing APIs that display low solubilities in aqueous media throughout the pH range, incorporation of a surfactant is advisable, although the levels used should be as low as possible.
