[The evaluation of non-isothermal short-term tests of drug solutions].

Non-isothermal short-term tests to examine the stability of drug solutions, are critically discussed with regard to their application to simple and complex reaction mechanisms. The influence of additional temperature dependences (ionic product of water, activity coefficient) is assayed. By example of the decomposition of tetracaine hydrochloride and acetylsalicylic acid, the evaluation of experimental results is discussed considering these factors.
