title: [Drug interactions].
abstract: Every alteration of the effect of a drug within the human body due to substances introduced from outside are considered drug interactions. Several types of these mutual actions are differentiated. They can be influenced with varying success according to the site of the interaction. An unusual variant of the interactions sometimes appears in genetically induced disturbances in the metabolism of drugs.
