Expected Learning Outcomes

Knowledge and understanding. The student will have to acquire the theoretical and practical skills useful for the recognition of organic compounds of pharmaceutical interest reported in the monographs of official pharmacopoeias, through specific chemical assay and instrumental analytical techniques. The student will also acquire the theoretical bases of the main analytical techniques for the analysis of active principles in biological matrices.

Applying knowledge and understanding. The student must be able to use the knowledge acquired in the context of instrumental analysis to develop and validate analysis protocols for the analysis of active ingredients in pharmaceutical forms and biological matrices.

Making judgments: The student will have to interpret the experimental results obtained relating to the analysis of active ingredients present in complex matrices.

Communication skills: At the end of the course the student will have to explain what has learned using appropriate terminology for a correct scientific presentation regarding the analytical techniques and the analysis of compounds of pharmaceutical interest.

Learning skills. The student will have to developed useful theoretical/practical skills in order to update and expand his knowledge with the aim of face new analytical problems.

Course Structure

Frontal lessons (42 hrs) and laboratory training (45 hrs).

Information for students with disabilities and / or SLD: To guarantee equal opportunities and in compliance with the laws in force, interested students can ask for a personal interview in order to plan any compensatory and / or dispensatory measures, based on the teaching objectives and specifications needs. It is also possible to contact the CInAP contact person (Center for Active and Participatory Integration - Services for Disabilities and / or SLD) of the DEPARTMENT OF DRUG AND HEALTH SCIENCES, Prof. Teresa Musumeci.


Required Prerequisites

The basic knowledge necessary for the understanding of the course concern: General and Inorganic Chemistry; Organic Chemistry; Physics; Analysis of Inorganic Substances for Pharmaceutical Use, and Quantitative Analysis of Drugs.

Attendance of Lessons

Attendance in the classroom is mandatory. The maximum limit of absences allowed is 30% as reported in the teaching regulations of the CdS which can be consulted on the website of the Department of Pharmaceutical and Health Sciences. Once this limit has been exceeded, it will not be possible to access the practical laboratory exercises.
