HOW DO ANTILEISHMANIASIS AGENTS WORK?

Antileishmaniasis agents are a class of drugs that are used to treat an infection called leishmaniasis. Leishmaniasis is a parasitic infection caused by protozoan parasites which are transmitted by the bite of infected female phlebotomine sandflies. This disease particularly affects some of the poorest people and is associated with malnutrition, population displacement, poor housing, a weak immune system, and a lack of financial resources.

Leishmaniasis is a tropical disease categorized into the following three types:

  • Visceral leishmaniasis: It is also known as ‘kala azar’ and is the most severe form of the disease, affecting the internal organs.
  • Cutaneous leishmaniasis: It is the most commonly seen type of disease affecting the skin.
  • Mucosal leishmaniasis: It affects the nose, mouth, and throat.
  • Antileishmaniasis agents are administered via the oral and intravenous or intramuscular routes. Oral medication is taken twice or thrice daily with food for 28 consecutive days.

Antileishmaniasis agents work in the following ways:

  • They work by stopping the growth of the parasites.
  • They bind to the thiol groups in the parasite and inhibit the formation of adenosine triphosphate and guanosine triphosphate.
  • This causes a decrease in the parasite’s DNA, RNA protein, and purine nucleoside triphosphate levels which further stops their macromolecular synthesis.

HOW ARE ANTILEISHMANIASIS AGENTS USED?

Antileishmaniasis agents are used in conditions such as:

Leishmaniasis (infection with Leishmania parasites which causes skin sores and affects several internal organs usually the spleen, liver, and bone marrow)

  • Visceral leishmaniasis due to Leishmania donovani
    • Cutaneous leishmaniasis due to Leishmania braziliensis, Leishmania guyanensis, and Leishmania panamensis
    • Mucosal leishmaniasis due to Leishmania braziliensis
  • Acute Myeloid Leukemia (a type of cancer that starts in the blood-forming cells of the bone marrow)
