What It Is and How It Works
Ivermectin is an antiparasitic agent that works by binding to invertebrate muscle and nerve cells, predominantly glutamate-gated chloride channels. This interaction increases the permeability of the cell membranes to chloride ions, resulting in paralysis and eventual death of the parasite. While primarily used to treat parasitic infections, its anti-inflammatory properties have been explored in various research contexts.
Indications / Uses
Ivermectin is primarily used for:
- Intestinal strongyloidiasis: Treats infections caused by the parasitic worm Strongyloides stercoralis.
- Onchocerciasis: Also known as river blindness, caused by the worm Onchocerca volvulus.
Off-label, ivermectin has been studied for other parasitic infections and potential viral infections, but these uses should be carefully supervised by a healthcare provider.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in oral tablet form and can also be found in topical creams for certain skin conditions.
