Abstract:
Opioids are an important component of the drug treatment of patients with acute and chronic pain. They differ in effectiveness, side effect profile and the risk of interactions. In this article the pharmacokinetic mechanisms of drug-drug interactions at the level of biotransformation are described and the clinical consequences which can arise are discussed. The relation of the active components to the two isoenzymes CYP2D6 and CYP3A4 is of major importance for assessing the potential drug-drug interactions of opioid analgesics at the level of the cytochrome P450 enzyme.
