Zusammenfassung
Arzneimittelinteraktionen sind auf Intensivstationen ein häufiges Problem. Dabei spielt
die Gesamtmenge der verschriebenen Medikamente bei kritisch kranken Patienten eine
große Rolle: Durchschnittlich werden hier 25 – 35 Medikamente pro Patient eingesetzt.
Fundierte Kenntnisse über entsprechende pharmakodynamische und pharmakokinetische
Mechanismen sind für die Behandlungssicherheit daher essenziell.
Abstract
Drug-drug interactions are common problems in intensive care units. Numerous studies
could demonstrate the impact of the total amount of prescribed drugs and the occurrence
of potential respectively manifest drug-drug interactions in critically ill patients.
The average number of clinically used drugs in this setting is approximately 25 – 35
per patient, thus the profound knowledge of pharmacodynamic and pharmakokinetic mechanisms
regarding drug interplay is important for treatment safety. This review aims to summarize
the current evidence of drug interactions in intensive care patients. It especially
features data regarding pharmacokinetics as main reason for clinically relevant drug-drug
interactions. The most important drug classes noted in this context are analgesics
and sedatives, antibiotics, antimycotics, antiepileptics, immune suppressive drugs,
prokinetics and gastric acid regulating drugs. Furthermore, some pharmacodynamic interactions
are described like QTc prolongation or serotonin syndrome. Additionally, a clinical
case is demonstrated regarding the malignant impact of rifampin co-medication in a
patient suffering from severe hypertension with the use of several antihypertensive
drugs.
