What It Is and How It Works
Ivermectin is an antiparasitic medication commonly used to treat a variety of parasitic infections in humans, especially those caused by nematodes (roundworms) and certain ectoparasites. Its effectiveness lies in its ability to bind to certain receptors in parasites, significantly increasing the cell membrane\’s permeability to chloride ions. This binding causes paralysis and eventually kills the parasite.
Indications / Uses
Ivermectin is approved for treating several parasitic infections, including:
- Onchocerciasis: Caused by the Onchocerca volvulus worm, leading to \”river blindness.\”
- Strongyloidiasis: Resulting from infection by the Strongyloides stercoralis worm.
- Scabies: A skin condition caused by microscopic mites that burrow into the skin.
- Lice infestations: Capable of effectively treating head lice infestations.
Additionally, ivermectin has received attention for its potential use against viral infections, but it is crucial to note that such applications remain under investigation and should not be considered standard or recommended outside of clinical trials or professional guidance.
