Bupropion and Oliceridine interaction

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.

…prolonged opioid adverse reactions and exacerbated respiratory depression, may occur when OLINVYK is used under the following conditions: In patients with decreased Cytochrome P450 (CYP) 2D6 function (poor metabolizers of CYP2D6 or normal metabolizers taking moderate or strong CYP2D6 inhibitors) [See Drug Interactions ( 7 ); Use in Specific Populations ( 8.8 )].

…oliceridine, which may lead to decreased efficacy, may occur under the following conditions: Concomitant use of OLINVYK with CYP3A4 inducers Discontinuation of a moderate or strong CYP3A4 or CYP2D6 inhibitor Closely monitor these patients at frequent intervals and consider supplemental doses of OLINVYK [see Dosage and Administration ( 2.2 ), Drug Interactions ( 7 )] .

Table 6: Clinically Significant Drug Interactions with OLINVYK Moderate to Strong Inhibitors of CYP2D6 Clinical Impact: Concomitant administration of a moderate to strong CYP2D6 inhibitor can increase the plasma concentration of oliceridine [see Clinical Pharmacology ( 12.3 )] , resulting in increased or prolonged opioid effects.

If a CYP2D6 inhibitor is discontinued, increase of the OLINVYK dosage may be considered until stable drug effects are achieved.

Additional predisposing conditions include diabetes mellitus treated with oral hypoglycemic drugs or insulin, use of anorectic drugs, excessive use of alcohol, use of benzodiazepines, sedatives/hypnotics, or opiates.
