Drugs Analysis II
Overview
The course "Drugs Analysis II" and "Laboratory of Drugs Analysis II", conducted through the mediu of both face to face lessons and practical lab experiments, gives the student a basic grounding in the field of quality control quality control of drugs in bulk and in drug formulations. Specifically, the course aims to provide the student with the fundamental skills for the analytical aspects of process development, structural identification and characterization of drugs, for the control of their stability and the characterization and quantitative analysis of impurities. Analytical methodologies used in therapeutic drug monitoring, identification of counterfeit drugs and medicines, and analysis of biotechnological drugs will also be covered. To begin with, the analytical methods reported in the current Official Pharmacopoeia (with particular reference to the European Pharmacopoeia, EP) will be evaluated and then knowledge will be provided which will allow students to develop analytical procedures for the process development, control of the structural identity, purity control and stability of new chemical entities. The course then goes on an overview of the assays provided by EP for the quality control of plant drugs and related phytoderivatives (extracts and essential oils) and for the chemical and instrumental recognition of the active ingredients contained in them. The course also includes an overview of chemical-analytical methods for the quality control of drugs of biotechnological origin. Finally, methods applied to therapeutic drug monitoring and the identification of counterfeit drugs and medicines will be covered.
The practical laboratory experiments (which include mandatory exercises) provide students with the ability to identify unknown substances listed in EP through the application of chemical and instrumental methods

Assessment methods and Criteria
For each of the two teaching units, the learning assessment is evaluated by a mark out of thirty with a minimum grade of 18/30.
The final result will come from the average of the marks obtained in the two teaching units weighted by the credit value of each unit.
Teaching unit: Drug Analysis 2
The exam consists of a written test which is related to the topics covered in class, and is articulated in several points with exercises and open-ended questions with a final grade out of thirty. The written test lasts 120 minutes.
In order to be able to take the examination, it is essential to register for the exam session through the online SIFA service of the University. The outcome of the written exam will be published on the Ariel portal of Unimi.
Teaching unit: Laboratory of Drug Analysis 2
The Laboratory unit does not include an examination, but an acknowledgement of attendance, which is granted only if the student has correctly performed at least 50% of the unknown analyses. The overall evaluation of the activity performed by the student in the exercises included in the Laboratory unit is made on the basis of the results of the analyses and is expressed in thirtieths.
During a solar year, there will be seven exams and the students can take consecutive exams without any constraining.
