What It Is and How It Works
Ivermectin is an antiparasitic medication that works by interfering with the nervous system of parasites, ultimately leading to their death. It is effective against a variety of parasites, including those that cause river blindness and strongyloidiasis. By binding to certain channels on nerve and muscle cells, ivermectin increases the permeability of these cells to chloride ions, leading to paralysis and death of the parasite.
Indications / Uses
Ivermectin is primarily indicated for the treatment of specific parasitic infections:
- River Blindness (Onchocerciasis): Common in parts of Africa and Latin America, this infection is caused by the parasite Onchocerca volvulus.
- Intestinal Strongyloidiasis: An infection caused by the parasitic worm Strongyloides stercoralis.
Ivermectin may also be used off-label for other parasitic conditions under the supervision of a healthcare provider. However, its use for non-parasitic conditions should be approached with caution and based on evidence from clinical sources.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several formulations, including:
- Oral Tablets: Commonly used for treating human parasitic infections.
