Antiparasitic medications are drugs designed to treat infections caused by parasites. These include a wide range of drugs that target different types of parasites such as protozoa, helminths, and ectoparasites. In gynecology, the focus is primarily on protozoal infections, such as those caused by _Trichomonas vaginalis_, and helminthic infections, like those caused by _Enterobius vermicularis_ (pinworm).
