• Opioid regimens that deliver best pain control reflect assay findings of cytochrome defects
  Most patients with multiple defects of the cytochrome P450 system, which is largely responsible for metabolizing opioids, naturally gravitated toward an opioid regimen primarily metabolized through the cytochrome P450 3A4 enzyme or a non-cytochrome, metabolic pathway, a new study suggests.
