CYP2D6 is a crucial enzyme belonging to the cytochrome P450 superfamily, primarily involved in the metabolism of a wide range of drugs and xenobiotics. This enzyme plays a significant role in drug metabolism by facilitating the oxidation of organic substances, which can lead to the activation or deactivation of therapeutic agents.
