These interactions were further demonstrated by isobologram analysis at variable potency ratios, wherein MiB/Pg-(Aq) exhibited outright synergistic interaction at all experimental concentrations, while Cp/Og-(EtOH), MiB/Cs-(Aq), and Cp/Cs-(Aq) exhibited antagonistic and synergistic interactions as their concentrations were inversely varied, respectively. In vitro sensitivity assessment of drug combinations for malaria is used to help predict clinically useful combinations. This evidence concerns the gene CP and malaria.
