Antiparasitics work through various mechanisms depending on the specific drug and the type of parasite. For instance:
Antiprotozoals like Chloroquine interfere with the parasite's ability to digest hemoglobin, which is crucial for its survival. Anthelmintics such as Albendazole inhibit the parasite's ability to produce energy, leading to its death. Ectoparasiticides like Permethrin work by disrupting the nervous system of the parasite, causing paralysis and death.
