Morphine cyp2d6
WebMothers with a CYP2D6 ultrarapid metabolizer phenotype may expose their infants to risk of adverse events when taking codeine while breastfeeding, by producing more of the active metabolite, morphine. Pharmacogenetic testing may be a valuable tool to identify such mothers, but testing can be costly. WebCYP2D6 genetic polymorphisms have the potential to affect the toxicity of their substrates. ... Opioid analgesics that do not rely on CYP2D6 for therapeutic activity, such as morphine and hydromorphone, may therefore be a better alternative to codeine and tramadol, with the limitation that these drugs have their own set of adverse reactions.
