Drug Interactions & Labeling Preventable Adverse Drug Reactions

This case demonstrates why it is important that health care practitioners report ADRs to the Food and Drug Administration (FDA). It was also a pivotal case resulting in recognition and definition of one type of preventable adverse drug reaction— drug interactions mediated by the cytochrome P450 pathway of drug.

It is worth considering how well a drug’s safety is defined prior to its approval and marketing. This will indicate how confident practitioners can be that a new drug’s safety profile has been fully defined.

Drug absorption also can be affected if the drug's ability to dissolve (solubility) is changed by another drug or if a substance (for example, food) binds to the drug and prevents its absorption.

For example, there may be major sedation when two drugs that can cause sedation are taken simultaneously, such as narcotics with antihistamines. Drug interactions also may occur when two drugs that have similar (additive) effects or opposite (canceling) effects on the body are administered together.
