Stability studies of drugs by stress study is a very important process which is done by treating the study drug with different stress agents, with the aim to define the critical factors affecting the stability of the drug, to accurately define the storage conditions of the drug, as well as to identify the resulting degradation products. In this paper, stress studies of bisoprolol fumarate were performed, in order to examine what are the stress agents that affect its stability. For the analysis previously optimized and validated HILIC method was used It was demonstrated that oxidative stress agent has the largest effect on the degradation of bisoprolol fumarate, and then the acid and base stress agent successively. Water, as a neutral medium, and light had no significant effect on the stability of bisoprolol fumarate. During degradation under acid conditions impurity A was formed and it was confirmed with UPLC/MS/MS method. In order to more clearly define the processes of degradation, k...inetic studies of degradation of bisoprolol fumarate have been carried out, in order to determine the order of the reaction rate of degradation and degradation half-time, which provided clearer definition of the mechanism of degradation.
