Drug Interactions between Dolutegravir and Artemether- Lumefantrine or Artesunate-Amodiaquine

Abstract
Across sub-Saharan Africa, patients with HIV on antiretrovirals often getmalaria and need cotreatment with artemisinin-containing therapies. We undertook two pharmacokinetic studies in healthy volunteers, using standard adult doses of artemetherlumefantrine or artesunate-amodiaquine given with 50mg once daily dolutegravir (DTG) to investigate the drug-drug interaction between artemether-lumefantrine or artesunateamodiaquine and dolutegravir. The dolutegravir/artemether-lumefantrine interaction was evaluated in a two-way crossover study and measured artemether, dihydroartemisinin, lumefantrine, and desbutyl-lumefantrine over 264 h. The dolutegravir/artesunate-amodiaquine interaction was investigated using a parallel study design due to long half-life of the amodiaquine metabolite, desethylamodiaquine and measured artesunate, amodiaquine, and desethylamodiaquine over 624 h.
