Listening to 'Drug Actions' Parts, 1 2 & 3 will earn you 52 Mins of CPD
Introduction:
This is a very interesting lecture that explains some of the basic principles underlying pharmacology. It will be very useful to all nurses.
In this lecture you will review methods of drug absorption, distribution and elimination. You will learn about the various ways in which drugs are absorbed and factors that affect absorption. Bioavailability is clearly defined and its implication for drug quality, brand substitution and the use of generic medications. In addition to reviewing factors that affect drug distribution, you will learn how therapeutic drug monitoring is used and how protein binding influences distribution. The lecturer explains hepatic metabolic elimination and reabsorption.
Learning Objectives:
The objectives of this session are to:
- Outline the methods through which the human body absorbs, distributes and eliminates medicines.
- Explain what is meant by bioavailability and how this differs depending on the route of administration and the brand of drug.
- Learn about brand substitution and the use of generic medicines e.g. why brands such as warfarin should NEVER be substituted.
- Why drugs that are administered intravenously do not undergo absorption.
- Explain the importance of dissolution on drug action.
- Discuss the isoenzymes and protein binding as they relate to drug action.
