एटाज़ानाविर और ब्यूप्रेनॉर्फिन का इंटरैक्शन

Examples: atazanavir, ritonavir Benzodiazepines : May increase buprenorphine-induced respiratory depression.

Evaluate patients starting CYP3A4 inhibitors or stopping CYP3A4 inducers at frequent intervals for respiratory depression.

Other PIs with CYP3A4 inhibitory activity (atazanavir and atazanavir/ritonavir) resulted in elevated levels of buprenorphine and norbuprenorphine, and patients in one study reported increased sedation.

Intervention: Evaluate patients taking BELBUCA and atazanavir with and without ritonavir and reduce the dose of BELBUCA if warranted.

Inhibitors of CYP3A4 Clinical Impact: The concomitant use of BELBUCA 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 BELBUCA is achieved.

REYATAZ ↓ atazanavir The coadministration of REYATAZ and buprenorphine without ritonavir is not recommended.

Opioids: buprenorphine REYATAZ or REYATAZ with ritonavir ↑ buprenorphine ↑ norbuprenorphine Coadministration of REYATAZ with ritonavir and buprenorphine warrants clinical monitoring for sedation and cognitive effects.

A dose reduction of buprenorphine may be considered.
