Quizplus · Accepted Answer

Drug interactions occur when one drug alters the effect of another drug. This can happen in different ways, such as by affecting the pharmacodynamics (how the drug works in the body) or the pharmacokinetics (how the drug is absorbed, distributed, metabolized and eliminated). It can also happen at different levels, such as on a molecular or cellular level within the body. It is important to be aware of potential drug interactions, as they can affect the effectiveness and safety of a medication.
