The mechanism of action, cautions, indications, contraindications, dosages, adverse effects, routes of administration, and interactions of anthelmintic, antiprotozoal, and antimalarial drugs. Concept introduction: Helmints are 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. This is achieved by analyzing the samples such as urine, sputum, feces, tissue, and blood. A drug that acts against 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. Numerous drugs that are used to treat malarial infections are also used to prevent protozoal infections. This includes pyrimethamine, chloroquine, atovaquone, and primaquine. Pentamidine, metronidazole, and iodoquinol are some of the antiprotozoal drugs used to treat non-malarial parasites.

Question

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.
