What It Is and How It Works
Ivermectin is an antiparasitic drug belonging to the macrocyclic lactone class. It is particularly effective against a variety of parasitic worms. The drug binds to glutamate-gated chloride ion channels in nerve and muscle cells of invertebrate parasites. This action results in increased permeability of the cell membrane to chloride ions and leads to paralysis and death of the parasite.
In humans, this mechanism effectively targets the parasites without affecting the host, making it a useful treatment for several parasitic conditions.
Indications / Uses
Ivermectin is approved for several specific uses:
- Treatment of river blindness (onchocerciasis).
- Treatment of intestinal strongyloidiasis.
- Treatment of other less common worm infections.
Off-label, ivermectin may be used for other conditions under the supervision of a healthcare provider. Off-label use should be carefully evaluated for safety and efficacy.
