What It Is and How It Works
Ivermectin belongs to a class of medications called anthelmintics, which are used to treat infections caused by worms. It works by binding to certain ion channels in parasites\' nerve and muscle cells, resulting in paralysis and eventual death of the parasite.
In more scientific terms, ivermectin binds selectively to glutamate-gated chloride channels, which are vital for the function of nerve and muscle cells. This binding increases the permeability of the cell membrane to chloride ions, leading to paralysis of the parasite and eventually eliminating the infection.
Indications / Uses
Ivermectin is primarily used to treat the following conditions:
- Onchocerciasis (river blindness)
- Strongyloidiasis (intestinal infections caused by the Strongyloides stercoralis worm)
- Scabies
- Head lice
Off-label uses include treatment of certain other parasitic infections and potentially other conditions requiring further research and should be undertaken only under medical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms such as tablets, topical creams, and injections. Tablets are most commonly used for parasitic infections.
Typical dosing depends on the specific condition being treated, the patient\'s weight, age, and overall health status, including liver and kidney function.
Given the variability, dosage should always follow the prescribing healthcare professional’s instructions rather than general recommendations.
