Introduction to Week 1

In this video, Dr Victoria Hewitt, introduces week one "Pharmacology and Physiology of Opioids" and explains our case study.
8.4
This week is about the pharmacology of opioids, including opioid receptors and how these drugs act at a cellular level to block the neurotransmission of the pain signal. We look at their absorption, metabolism, and elimination, creating a foundation to understand opioid side effects, routes of administration, and the principles of dosing intervals. This week, you’ll also be introduced to our fictionalised case study, which is based around common scenarios that you may encounter in practice. This is designed to put your learning into context and to reflect on your own clinical practice.
In the first week, we explore the pharmacodynamics and pharmacokinetics of opioids.
Pharmacodynamics describes a drug ‘s effects on the body. Pharmacokinetics is concerned with how the body affects the drug. To understand the theory of the drug’s administration, dosing, benefits and side effects both need to be considered.
You will also meet a fictionalised case study, based on common clinical scenarios. As you progress through the course, you’ll have the oportunity to reflect on this case study and test theory in practice.
