ABSTRACT

A drug interaction implies a likely modification of the expected response to the drug in an individual, due to the exposure of the individual to one or more drugs or substances. Drug interactions which produce adverse reactions in patients are unintentional, yet drug interactions may also be intentional if they provide an improved therapeutic response or allow for a more convenient dosing regimen [1]. Drug interactions include drug-drug interactions, food-drug interactions and chemical-drug interactions, such as the interaction of a drug with alcohol or tobacco.
