Answer

(a) Prescription for acute uncomplicated P. falciparum malaria

  • Artemisinin-based combination therapy (ACT) — e.g., Artesunate + Sulfadoxine-pyrimethamine, or Artemether-Lumefantrine, for 3 days
  • (If severe/complicated: IV Artesunate, followed by a full course of ACT)

(b) Mechanism of action (Chloroquine, as an example)

  • Concentrates in the parasite’s food vacuole and inhibits haem polymerase, which normally converts toxic free haem into inert haemozoin
  • Accumulation of toxic free haem damages parasite membranes, killing the parasite

(c) Drugs for chemoprophylaxis of malaria

  • Mefloquine
  • Doxycycline (Chloroquine + Proguanil is also used in areas without chloroquine resistance)
