What It Is and How It Works
Ivermectin is an antiparasitic agent belonging to the avermectin class of drugs. It operates by binding to glutamate-gated chloride ion channels, which are present in the nerve and muscle cells of parasites. This binding results in increased permeability of the cell membrane to chloride ions, leading to paralysis and death of the parasite. Ivermectin\’s action selectively targets parasites, sparing human cells, which is why it\’s effective as an anti-parasitic treatment.
Indications / Uses
Ivermectin is primarily approved for treating several types of parasitic infections. The most common include:
- Onchocerciasis: A condition caused by the Onchocerca volvulus worm, leading to skin and eye lesions.
- Strongyloidiasis: An intestinal infection caused by Strongyloides stercoralis, a type of roundworm.
Though ivermectin has been investigated for other off-label uses, such as antiviral properties, these applications should only be pursued under strict clinical supervision as evidence varies significantly.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available mainly in tablet form, with the most common strength being 12 mg. The dosing of ivermectin can vary based on the type and severity of the infection, the patient\’s weight, and individual health factors. Generally, the dose is a single or short course, but it is vital to follow the exact prescription provided by a healthcare provider.
Dosing adjustments may be necessary for individuals with specific conditions like liver or kidney impairment. Pregnant and breastfeeding women, as well as the elderly, should use ivermectin with caution and under medical supervision.
