Does Abacavir Sulfate Dolutegravir Sodium Lamivudine Interact with Atazanavir?
CDI records a unknown classification for Abacavir Sulfate Dolutegravir Sodium Lamivudine and Atazanavir. The stored summary is: Using cross-study comparisons to historical pharmacokinetic data for each interacting drug, dolutegravir did not appear to affect the pharmacokinetics of the following drugs: atazanavir, darunavir, efavirenz, etravirine, fosamprenavir, lopinavir, ritonavir, and boceprevir. Etravirine significantly reduced plasma concentrations of dolutegravir, but the effect of etravirine was mitigated by coadministration of lopinavir/ritonavir or darunavir/ritonavir and is expected to be mitigated by atazanavir/ritonavir ( Table 6 ) [see Drug Interactions ( 7.3 ), Clinical Pharmacology ( 12.3 )] . Concomitant Drug Class: Drug Name Effect on Concentration Clinical Comment HIV-1 Antiviral Agents Non-nucleoside reverse transcriptase inhibitor: Etravirine a ↓Dolutegravir Use of TRIUMEQ or TRIUMEQ PD with etravirine without coadministration of atazanavir/ritonavir, darunavir/ritonavir, or lopinavir/ritonavir is not recommended. Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This record was extracted from drug labeling through openFDA. NIH/NLM RxNorm is used for drug identities.
