What do drug interactions refer to in pharmacology?

Drug interactions in pharmacology refer to instances where one drug alters the effect of another drug. This can occur in various ways, potentially enhancing or diminishing the therapeutic effects, increasing toxicity, or causing adverse side effects. Understanding drug interactions is crucial in clinical practice, as they can significantly impact patient safety and treatment efficacy.

For example, when two medications are taken together, one may increase the level of the other in the bloodstream, leading to an increased risk of side effects or toxicity. Conversely, one medication might inhibit the metabolism of another, ultimately reducing its effectiveness. Recognizing and managing these interactions is an essential aspect of nursing practice to ensure safe and effective medication administration for patients.
