| Popis: | Currently, in pharmaceutical analysis, great importance is given to forced degradation studies, which can greatly help to predict the shelf life of the drug, but also for identification of possible degradation products. These studies enable investigation of stability indicating method, then it is used to test the active substances intrinsic/inner molecular stability, as well as defining active substances impurity profiles. In this work forced degradation studies of amlodipine besylate and bisoprolol fumarate either individually and in mixtures, was performed, where the method of hydrophilic interaction liquid chromatography was used, and any possible changes in the concentration of samples were followed. The results showed that the test compounds are sensitive to the tested stress agents, especially amlodipine besylate, and that both of these compounds showed increased stability in the mixture in comparison to individual analysis. |
