Commonly referred to as drug-drug interactions, this phenomenon usually occurs when a drug affects the expression or function of a metabolic enzyme or transporter. Since metabolism is the primary mechanism for elimination of most drugs, changes in the enzymes responsible for drug metabolism can lead to undesirable increases (or decreases) in the plasma concentration of drugs.

A drug interaction is a reaction between two (or more) drugs or between a drug and a food, beverage, or supplement. Taking a drug while having certain medical conditions can also cause a drug interaction. For example, taking a nasal decongestant if you have high blood pressure may cause an unwanted reaction.

In more simplistic terms, drug-drug interactions occur when the presence of Drug A affects the levels of Drug B in the body. These effects can increase or decrease the levels of Drug B. The current regulatory environment focuses on only metabolic drug interactions because they are the best understood, and easiest to evaluate.

Drug–drug interactions (DDIs) occur when one drug interferes with the pharmacological activity of another [58]. These interactions can result in decreased effectiveness and/or increased toxicity. These interactions can result in decreased effectiveness and/or increased toxicity.

Drug-Drug Interaction DDI is defined as “The pharmacologic or clinical response to the administration of a drug combination different from that anticipated from the known effect of the two agents when given alone”. From: Pulmonary Pharmacology & Therapeutics, 2014
