HSNS565 PHARMACODYNAMICS AND THE QUALITY USE OF MEDICINES ASSESSMENT ANSWER

Pharmacodynamics is the study of the effects of a drug on the human body. These effects can be biochemical and physiologic that involves a lot of activities. These include receptor binding, post-receptor effects as well as several chemical interactions that prevail inside of a human body. As per our nursing assignment help experts, there can be several reasons that can affect the Pharmacodynamics in a human body. These are:

  • Any disorder or disease
  • Use of different drugs
  • The process of ageing

Before we get to the roots of an HSNS565 Pharmacodynamics and the Quality Use of Medicines Assessment Answer, let us talk about some vital concepts that play a crucial role in these assignments.

What Are Pharmacodynamics Interactions?

Primarily, Pharmacodynamics is studying the relationship between how much drug is concentrated at the action site and the effect it has on the human body. Several drugs interact and Pharmacodynamics interactions are the process by which the effect of one drug changes due to the influence of another drug.

Generally, there are 4 types of Pharmacodynamics interactions that take place in a human body. These are:

1. Synergistic interactions

This is the interaction wherein the way an index drug behaves is enhanced or influenced by another drug. For instance, when an antihypertensive agent is given to another agent, the effects of the first induced drug get influenced.

2. Antagonistic

In this interaction, the effect of the index drug gets opposed to the introduction of another drug. For instance, the way beta adreno-receptor behaves against beta-agonists.

3. Interactions secondary to changes in drug transport mechanisms

Some interactions occur due to the change in the mechanisms of transportation of drug in the human body.

4. Disturbance in fluid and electrolyte balance

When there is a disturbance in the fluid levels of two drugs, this type of Pharmacodynamics interaction takes place.
