The more commonly used anthelmintic, antiprotozoal, and antimalarial drugs. Concept introduction: Helmints comprised of complex multicellular structures. Therefore, the anthelmintic drugs are very specific in destroying the worms. Before administering the anthelmintic drugs, the causative worm (in an infected host) must be identified exactly. This is achieved by analyzing the samples such as urine, sputum, feces, tissue, and blood. A drug that acted against the malaria is referred to as an antimalarial drug. The quinine (original drug) acts by inhibiting the reproduction and growth of the malarial parasites (Plasmodium), which thrives in the red blood cells of the victims. There are numerous drugs that are used to treat the malarial infections which are also used to prevent the protozoal infections. This includes the pyrimethamine, chloroquine, atovaquone, and primaquine. Pentamidine, metronidazole, and iodoquinol are some of the antiprotozoal drugs used to treat the nonmalarial parasites.

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.
