HOW DO ANTIPARASITIC AGENTS WORK?

Antiparasitic agents are a class of medications used in the management and treatment of parasitic diseases, such as those caused by helminths, amoeba, parasitic fungiprotozoa, and ectoparasites. Parasites are microorganisms that live on or inside another organism known as the host organism and benefit at the expense of their host organism. Antiparasitic agents do not work for viral infections such as the common cold and flu.

Antiparasitics are one of the antimicrobial drugs which can include the following:

  • Protozoa: unicellular organisms, particularly high propensity to infect immunocompromised patients such as those with acquired immune deficiency syndrome
  • Helminths: parasitic worms, transmitted via accidental ingestion, skin penetration, or a vector bite
  • Ectoparasites: organisms that live externally on the skin of hosts. They include mites, fleas, ticks, lice, and bedbugs.
  • These are administered orally as a tablet and a suspension (liquid).

Antiparasitic agents work in the following ways:

  • They work by stopping the growth of certain bacteria and parasites.
  • In addition, they eventually kill the invading parasites.
