Atazanavir + Buprenorphine Interaction
Unknowninteraction on record
Description
Other PIs with CYP3A4 inhibitory activity (atazanavir and atazanavir/ritonavir) resulted in elevated levels of buprenorphine and norbuprenorphine after sublingual administration, and patients in one study reported increased sedation. Symptoms of opioid excess have been found in postmarketing reports of patients receiving sublingual buprenorphine and atazanavir with and without ritonavir concomitantly. Intervention: If treatment with atazanavir with and without ritonavir must be initiated in a patient already treated with SUBLOCADE, the patient should be monitored for signs and symptoms of over-medication.
