ब्यूप्रेनॉर्फिन और नालोक्सोन और लेनाकैपाविर का इंटरैक्शन

Opioid Antagonist: naloxegol ↑ naloxegol Avoid use with SUNLENCA; if unavoidable, decrease the dosage of naloxegol and monitor for adverse reactions.

Narcotic analgesic for treatment of opioid dependence: buprenorphine, methadone buprenorphine: effects unknown methadone: effects unknown Initiation of buprenorphine or methadone in patients taking SUNLENCA: Carefully titrate the dose of buprenorphine or methadone to the desired effect; use the lowest feasible initial or maintenance dose.

Initiation of SUNLENCA in patients taking buprenorphine or methadone: A dose adjustment for buprenorphine or methadone may be needed.

Narcotic analgesics metabolized by CYP3A: e.g., fentanyl, oxycodone ↑ fentanyl ↑ oxycodone Careful monitoring of therapeutic effects and adverse reactions associated with CYP3A-metabolized narcotic analgesics (including potentially fatal respiratory depression) is recommended with co-administration. tramadol ↑ tramadol A decrease in dose may be needed for tramadol…

Sedatives/Hypnotics: midazolam (oral) triazolam ↑ midazolam (oral) ↑ triazolam Use with caution when midazolam or triazolam is concomitantly administered with SUNLENCA 7.4 Drugs without Clinically Significant Interactions with SUNLENCA Based on drug interaction studies conducted with SUNLENCA, no clinically significant drug interactions have been observed with:…

Inhibitors of CYP3A4 Clinical Impact: The concomitant use of buprenorphine and CYP3A4 inhibitors can increase the plasma concentration of buprenorphine, resulting in increased or prolonged opioid effects, particularly when an inhibitor is added after a stable dose of buprenorphine and naloxone sublingual tablet is achieved.

After stopping a CYP3A4 inhibitor, as the effects of the inhibitor decline, the buprenorphine plasma concentration will decrease [see Clinical Pharmacology (12.3) ] , potentially resulting in decreased opioid efficacy or a withdrawal syndrome in patients who had developed physical dependence to buprenorphine.

If a CYP3A4 inhibitor is discontinued, consider increasing the buprenorphine and naloxone sublingual tablets dosage until stable drug effects are achieved.

CYP3A4 Inhibitors and Inducers: Monitor patients starting or ending CYP3A4 inhibitors or inducers for potential over- or under- dosing.

Antiretrovirals: Patients who are on chronic buprenorphine treatment should have their dose monitored if NNRTIs are added to their treatment regimen.
