Drug of choice for Falciparum Malaria is
**Core Concept**
Artemisinin-based combination therapies (ACTs) are the first-line treatment for uncomplicated falciparum malaria due to their high efficacy, rapid action, and lower risk of resistance development. These combination therapies typically involve an artemisinin derivative paired with a longer-acting partner drug, such as lumefantrine, mefloquine, or sulfadoxine-pyrimethamine.
**Why the Correct Answer is Right**
The correct answer is **Artemether-Lumefantrine** (Coartem), which is a widely used ACT for treating uncomplicated falciparum malaria. Artemether quickly kills the parasite, while lumefantrine provides sustained coverage to prevent relapse. This combination is particularly effective against multidrug-resistant strains of Plasmodium falciparum. The recommended dose for adults and children is two tablets twice a day for three consecutive days.
**Why Each Wrong Option is Incorrect**
**Option A:** Chloroquine is not the drug of choice for falciparum malaria due to widespread resistance in many parts of the world.
**Option B:** Sulfadoxine-pyrimethamine (Fansidar) is often used as a partner drug in ACTs but is not a suitable monotherapy for treating falciparum malaria.
**Option C:** Mefloquine (Lariam) is an alternative partner drug in some ACTs but is not the preferred choice for uncomplicated falciparum malaria.
**Clinical Pearl / High-Yield Fact**
When treating falciparum malaria, it is essential to use ACTs as recommended to minimize the risk of resistance development and ensure effective parasite clearance.
**Correct Answer: C. Mefloquine (Lariam)**
