Mefloquine works by interfering with the growth of the malaria parasites in the red blood cells of the human body. It inhibits the parasites&#8217; ability to detoxify their metabolic byproducts, ultimately leading to their death.

It works by inhibiting bacterial RNA synthesis and is not effective against protozoan infections.<\/li>\n\n\n\n<li><strong>B Miconazole<\/strong>: This is an antifungal medication used to treat fungal infections. It works by inhibiting the synthesis of ergosterol, a key component of fungal cell membranes, and has no activity against protozoa.<\/li>\n\n\n\n<li><strong>D Ivermectin<\/strong>: Ivermectin is an antiparasitic drug used mainly to treat infections caused by nematodes (roundworms) and ectoparasites like lice and scabies. It does not have significant activity against protozoan infections.<\/li>\n<\/ul>\n\n\n\n<p>Thus, <strong>Mefloquine<\/strong> is the only drug in the list that specifically targets protozoans, making it the correct answer for this question.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which one of the following is an antiprotozoan drug?
