What You'll Learn
Drug interactions are a crucial topic on the PTCB (PTCE) exam, as pharmacy technicians must have a strong understanding of how different medications can interact with one another. Drug interactions can occur when two or more medications are taken together and can result in unwanted side effects, reduced efficacy, or even dangerous health consequences. By mastering the concepts of drug interactions, pharmacy technicians can help ensure the safe and effective use of medications for patients.
Key Concepts
Synergistic Interaction
When two drugs taken together produce a greater effect than the sum of their individual effects.
Antagonistic Interaction
When two drugs taken together produce a lesser effect than the sum of their individual effects.
Pharmacokinetic Interaction
Occurs when one drug alters the absorption, distribution, metabolism, or excretion of another drug, resulting in changes in the drug's concentration in the body.
Pharmacodynamic Interaction
Occurs when one drug alters the effects of another drug at the receptor or target site, regardless of the drug's concentration in the body.
Contraindication
A situation in which a drug should not be used because it may be harmful to the patient.
Common Mistakes to Avoid
- Failing to consider the potential for drug interactions when dispensing or administering medications.
- Overlooking the risk of interactions between over-the-counter medications and prescription drugs.
- Misunderstanding the difference between synergistic and antagonistic interactions.
- Neglecting to check for potential interactions when a new medication is added to a patient's regimen.
- Assuming that all drug interactions are necessarily harmful or dangerous.
