TECNOLOGIA FARMACEUTICA 2 - SISTEMI DI RILASCIO AVANZATO DEI FARMACI
Module SISTEMI DI RILASCIO AVANZATO DEI FARMACI

Academic Year 2024/2025 - Teacher: LUCIA MONTENEGRO

Expected Learning Outcomes

The aim of this course is to provide the student with knowledge and expertise about the strategies exploited in the field of drug-modified release and targeting. In particular, the course focuses on the fundamental concepts of drug controlled delivery and targeting  illustrating the technological properties and the pharmaceutical applications of  the main controlled drug delivery systems. 

Course Structure

Frontal lessons (4 CFU) and laboratory activities in groups (1 CFU). Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.

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.

Required Prerequisites

Basic knowledge of organic chemistry and pharmaceutical technology.

Attendance of Lessons

Attendance is mandatory and is gained attending at least 70% of lessons.
