Antiprotozoal medications are drugs used to treat infections caused by protozoa, which are single-celled organisms. These infections can lead to diseases such as malaria, amoebiasis, and giardiasis. Antiprotozoal drugs work by targeting the life cycle of the protozoa, disrupting their ability to reproduce and survive in the human body. Common antiprotozoal medications include metronidazole and quinine. These drugs can be administered in various forms, such as tablets or injections, depending on the severity of the infection. By effectively eliminating protozoa, antiprotozoal treatments help restore health and prevent complications associated with these infections.
