Study-Unit Description


TITLE Overview of Drug Classes and Function

LEVEL 01 - Year 1 in Modular Undergraduate Course


DEPARTMENT Clinical Pharmacology and Therapeutics

DESCRIPTION This study-unit will introduce students to the classification and general actions of drugs used in pharmacological management. The topics covered will include the different types of drugs (conventional small molecules, biotherapeutics, gene therapy, vaccines etc), their pharmacological classification and how their modes of action contribute to disease management. The major drug classes including drugs acting on the cardiovascular, respiratory, nervous, intestinal, renal and reproductive systems, as well as antibiotics and drugs acting on pain, inflammation and oncological targets will be broadly discussed.

This will form a sound basis for a more detailed pharmacology of every drug class which will be delivered across several study-units, later on during the course.

Study-unit Aims:

- Introduce students to the pharmacological classification of drugs used in therapeutics, and distinguish between classification based on chemical structure, classification based on pharmacodynamic action, and classification based on disease targets;
- Explain the naming systems used for drugs, i.e. chemical, generic (e.g. the INN system) and tradename systems;
- Formulate a framework within which students can understand how drug classes may differ from each other, but may however exert similar actions through different mechanisms;
- Provide students with a groundwork which helps them to integrate drug function with drug class;
- Provide an overview of pharmacological actions and uses of major drug classes.

Learning Outcomes:

1. Knowledge & Understanding
By the end of the study-unit the student will be able to:

- Explain different criteria on which drugs may be classified;
- Discuss the general therapeutic and adverse pharmacological actions associated with different drug classes;
- List different drug naming systems and identify to which system a given drug name applies;
- Discuss specialized drug classes such as biotherapeutic agents and gene therapy.

2. Skills
By the end of the study-unit the student will be able to:

- Relate drug class to function and to target organ systems;
- Deduce the general actions of a drug from the class/es that it belongs to;
- Use the INN (international non-proprietary name) nomenclature system to identify the class of a drug, from its generic name.
