Drug Interactions with Cannabidiol (CBD): Cause for Concern?
Webthe pharmacokinetic drug-drug interactions associated with CYP3A4 isoenzyme. Drug interactions may be most apparent when patients are stabilized on the affected drug and the CYP3A4 inhibitor is then added to the regimen. Temporal relationships between the administration of the drug and CYP3A4 inhibitor may be important in The CYP3A4 gene exhibits a much more complicated upstream regulatory region in comparison with its paralogs. This increased complexity renders the CYP3A4 gene more sensitive to endogenous and exogenous PXR and CAR ligands, instead of relying on gene variants for wider specificity. Chimpanzee and human CYP3A4 are highly conserved in metabolism of many ligands, although four amino acids positively selected in humans led to a 5-fold benzylation of 7-BFC in t… WebMitapivat.
