Drug analysis 2 and laboratory of drug analysis 2

A.Y. 2019/2020
Overall hours
Learning objectives
The lectures and the individual laboratory training of Drug Analysis II and Laboratory of Drug Analysis II are aimed at providing the student with the knowledge and the practice of chemical and instrumental methods for the identification of the substances reported in European Pharmacopoeia monographs, improving his critical skills in approaching analytical challenges in the pharmaceutical field.
Expected learning outcomes
At the end of the course, the student will be able to understand the theoretical aspects of the principal techniques of identification and analysis of pharmaceutical substances and to properly apply them so as to answer the questions of the conclusive written examination.

Individual laboratory training

Recognition of organic and metallorganic substances of pharmaceutical interest
Introduction to the analysis of organic compounds. Organoleptic examination. Combustion tests and residue analysis, recognition of metals in organometallic substances registered in the F.U.
Preparation of Lassaigne's solution for the detection of nitrogen, sulfur, halogens, phosphorus. Solubility of organic substances: solubility in water and reactive solvents; classification of substances based on their solubility.
Assays for the recognition of functional groups in organic substances: alcohols, aldehydes, ketones, polyalcohols, sugars, carboxylic acids, α-oxyacids, phenols, amines, amino acids, esters, amides.
Examination of the substances registered in the F.U. Pharmaceutical substance classes: general and specific tests for alkaloids, sulpha, xanthine, glycosides, various substances.
Recognition of inorganic substances of pharmaceutical interest.
Prerequisites for admission
To conveniently attend the lessons, the student should possess basic knowledge of organic chemisty, medicinal chemistry and analytical chemistry.

Assessment methods and Criteria
Individual laboratory training: attendance is assigned if 50% analyses are correct and it is valued from 1/30 to 6/30 points depending on the results of the analyses. These points add to the points resulting from the final written exam, whose top score is 24/30.

The final written exam has the following characteristics:

It includes (i) open questions (short answers are required in the prefixed number of lines reported in the exam format) and (ii) multiple choice questions dealing with all topics covered by the course by which the student should demonstrate his knowledge and understanding as well as his capacity to discuss the key concepts of each topic. The mark of the exam will be rapidly recoded and the student could accept or neglect this within the provided deadline. Before this deadline, a meeting will be scheduled during which the students can analyze and discuss the results of their exam.

During a solar year, there will be seven exams and the students can take consecutive exams without any constraining.
