What Ivermectin Is and How It Works
Ivermectin is a medication with broad-spectrum antiparasitic action. It works by binding to ion channels in nerve and muscle cells of parasites, causing increased permeability to chloride ions. This mechanism leads to paralysis and death of the parasite. In terms of its chemical nature, ivermectin is a macrocyclic lactone, originally derived from a soil organism.

Ivermectin is primarily indicated for the treatment of parasitic infections. Some of the recognized uses include:
- Onchocerciasis: a parasitic infection caused by Onchocerca volvulus, most found in Africa.

- Off-label uses in other parasitic infections like head lice and scabies have been reported but should be overseen by a healthcare professional.
