Topic

Based on the previously acquired knowledge of pharmaceutical chemistry and pharmaceutical technology, the course material provides an overview of the international system of requirements for drug stability tests, and the requirements for performing and evaluating the tests. Based on the test results of specific pharmaceutical compounds and pharmaceutical preparations, it describes the chemical and physico-chemical bases of the decomposition processes of pharmaceutical compounds. It provides an explanation of the nature of the most common chemical incompatibilities and their consequences and describes the possible technological methods of preventing them.

Conditions for acceptance of the semester

During the semester (weeks 7 and 12), students write two mandatory written papers, which are evaluated using a percentage rating. At least one of the papers written must be graded at 60%, and the average of the papers written must be at least 50%. It is possible to write a remedial paper in the 13th week. The result of the paper is added to the results of previously written papers.
