OVERVIEW

The course deals with the pre-treatment and the quantitative determination of substances of pharmaceutical interest. It is developed with theoretical and practical lessons. The topics of the course are listed as follows.

AIMS AND CONTENT

LEARNING OUTCOMES

The course consists of  lectures and individual trainings in laboratory, aims to provide a basic understanding about the methods for the pre-treatment and the quantitative determination of compounds with medicinal use.

AIMS AND LEARNING OUTCOMES

The course allows to acquire theoretical and practical information regarding the main methods of quantitative analysis of drugs such as volumetric analysis, in particular in the areas of acid-base, complexometric, redox and precipitation titrations. Sample pretreatment and drug determination methods include instrumental analysis such as gas chromatography and HPLC. The laboratory activities concern the dosage of drugs and purification techniques of the sample.

TEACHING METHODS

The course is developed with theoretical and practical lessons.
