Definition of Antiprotozoal drug - MedicineNet.
Antiprotozoal drug, any agent that kills or inhibits the growth of organisms known as protozoans. Protozoans cause a variety of diseases, including malaria and Chagas’ disease. While protozoans typically are microscopic, they are similar to plants and animals in that they are eukaryotes and thus have a clearly defined cell nucleus.Many antiprotozoal drugs were used empirically long before their mechanism of action was known. The sulfa drugs, which block folate synthesis in malaria parasites, are one example. The rapid multiplication rate of many parasites increases the chances for mutation; hence, changes in virulence, drug susceptibility, and other characteristics may take place.Types of Students Classification Essay — Writing Guide with Examples.

Antiprotozoal agents or antiprotozoal drugs is a class of pharmaceuticals used in treatment of protozoan infection. The most populat anti protozoal drugs are as follows: Metronidazole.The major antiprotozoal agents include antitrichromonarial, antitrypanosomals, and antileishmanial. Trypanosomes and leishmania are the causative agents of African sleeping sickness, Chagas disease, nagana cattle disease, kala-azar, and oriental sore. All these parasitic protozoa lack the nearly ubiquitous enzyme glutathione reductase (GR).
Although they are often over-prescribed, antimicrobial agents are a critical defense against microbial infections. The sources of microbial infections include bacteria, viruses, funguses, and parasites. Therefore, the key categories of antimicrobial pharmaceutical agents are antibiotics, antifungals, antiprotozoal, and antiviral drugs.
