“In the present study, Charunwatthana et al administered NAC 2 hours after the first dose of artesunate and measured parasitemia every 6 hours to see whether NAC would impair parasite killing by artesunate.”
“In vitro, the parasiticidal effect of artesunate is reduced when given simultaneously with NAC , but is unaffected when NAC is given 2 hours after artesunate (12).”
