Established antimalarial drugsa
Drug | Role | Best Feature(s) | Limitations |
---|---|---|---|
Chloroquine | TX of and CP against non- Pf and sensitive Pf parasites | Very safe; low cost; long half-life | Widespread R |
Quinine/quinidine | Best TX for Pf malaria; low cost | Limited R; rapidly acting | Fairly toxic (cinchonism, cardiac) |
Amodiaquineb | TX of R Pf malaria | Low cost | Toxicity (bone marrow, liver); R common |
Mefloquine | CP against R Pf malaria; not approved for TX in United States | Relatively little R, though increasing; long half-life | Moderately toxic (mostly CNS); high cost; R in SE Asia |
Fansidar | TX of Pf malaria; no longer recommended for CP | Relatively low cost; long half-life | Skin toxicity (can be fatal); increasing R |
Primaquine | Eradication of chronic liver stage Pv, Po malaria | Only drug for this indication | Hemolysis with G6PD deficiency; increasing R |
Proguanilb | CP only (often with chloroquine) | Low cost; nontoxic | R common |
Maloprimb | CP only (often with chloroquine) | Low cost | R common; skin rashes |
Tetracyclines | CP; TX of Pf malaria in combination with quinine | Low cost | Skin and gastrointestinal toxicity |
