Question
f a drug is active against the preerythrocytic stage of the malarial parasite it will be useful as a: *1 pointA. Suppressive prophylacticB. Causal prophylacticC. Clinical curativeD. Radical curative
Solution
The preerythrocytic stage of the malarial parasite is the stage before the parasite enters the red blood cells. If a drug is active against this stage, it means it can prevent the parasite from entering the red blood cells and causing the symptoms of malaria. Therefore, a drug active against the preerythrocytic stage of the malarial parasite will be useful as a:
B. Causal prophylactic
A causal prophylactic is a type of drug that prevents malaria by killing the parasites in the liver before they reach the bloodstream and invade the red blood cells.
