Webaccelerated testing), humidity (e.g., 75% RH or greater) where appropriate, oxidation, and photolysis on the drug substance. The testing should also evaluate the susceptibility of the drug substance to hydrolysis across a wide range of pH values when in solution or suspension. Photostability testing should be an integral part of stress testing. Web1 nov. 2009 · The relationship between moisture content and water activity of a product is described by its moisture sorption isotherms—curves relating them to each other at specific temperatures. Moisture sorption isotherms are unique to each product and temperature. There are several methods for determining the moisture isotherms.
