What It Is and How It Works
Ivermectin is an antiparasitic medication often used to treat infections caused by certain parasitic worms. It belongs to a class of medications known as antiparasitic agents. Ivermectin works by binding to and activating glutamate-gated chloride ion channels present in nerve and muscle cells of the parasite, resulting in paralysis and death. This mechanism is especially effective against parasites like worms and mites.
Indications / Uses
Primarily, ivermectin is approved for the treatment of parasitic infections such as:
- Onchocerciasis (river blindness)
- Intestinal strongyloidiasis
- Scabies (although more so through topical applications)
There have been ongoing discussions about its potential off-label uses, but such applications should only be considered under professional supervision due to varying evidence and potential risks.
