Physicians look at drug-drug interactions (DDI), or more correctly xenobiotic interactions, in an emotional mixture of fear and interest, due to the apparently countless number of adverse drug effects (ADE) that can occur. The interactions as such are seen as errors; however, interactions cannot be avoided and are an inevitable part of the normal work of physicians. The problem is how to recognize interactions and how to handle them. A xenobiotic interaction can often even improve the effectiveness of a pharmacotherapy and minimize the risks. If all examples of what can possibly happen are not necessarily counted, the flood of information becomes relatively manageable. There are only seven different classes of interactions, four pharmacodynamic and three pharmacokinetic interactions. Currently, there are hotlines and both analogue as well as digital databanks to answer questions and address uncertainties, unfortunately of markedly different quality! Aids, such as therapeutic drug monitoring (TDM) supplement these offers. Every pharmacokinetic interaction can be recognized by determination of the concentration of the active agent. The comprehensive clinical pharmacological TDM report explain the information contained in the concentration of the active agent about the individual patient from whom the blood was drawn. All physicians can learn how to compile the clinical pharmacological TDM report by themselves or they can request it in interdisciplinary cooperation via a council. Medical expertise in handling xenobiotic interactions not only opens the door to adaptation of the pharmacotherapy to the needs of the individual patient but also saves huge budget resources for the healthcare system.
