Risk of Use in Patients with Decreased Cytochrome P450 2D6 Function or Concomitant Use or Discontinuation with Cytochrome P450 3A4 Inhibitors and Inducers Risk of Increased Oliceridine Plasma Concentrations Increased plasma concentrations of oliceridine, which may result in prolonged opioid adverse reactions and exacerbated respiratory depression, may occur when…
In patients taking a moderate or strong CYP3A4 inhibitor In patients with decreased CYP2D6 function who are also receiving a moderate or strong CYP3A4 inhibitor Discontinuation of a CYP3A4 inducer These patients may require less frequent dosing of OLINVYK.
Examples: Paroxetine, fluoxetine, quinidine, bupropion Moderate to Strong Inhibitors of CYP3A4 Clinical Impact: The concomitant administration of moderate to strong CYP3A4 inhibitors can increase the plasma concentration of oliceridine, resulting in increased or prolonged opioid adverse reactions.
After stopping a CYP3A4 inhibitor, as the effects of the inhibitor decline, the oliceridine concentration may decrease, resulting in decreased opioid efficacy or a withdrawal syndrome in patients who had developed physical dependence to oliceridine [see Warnings and Precautions ( 5.14 )] .
If a CYP3A4 inhibitor is discontinued, increase of the OLINVYK dosage may be considered until stable drug effects are achieved.
