What It Is and How It Works
Ivermectin is an anti-parasitic medication known for its effectiveness against a range of parasitic infections primarily affecting humans in developing countries. It works by binding to certain channels in the nerve and muscle cells of parasites, causing paralysis and death of the targeted organism. This action is specific to invertebrate organisms like worms and does not affect the human host when taken correctly.
In technical terms, ivermectin acts on the glutamate-gated chloride channels found in the cells of many parasites. By opening these channels, it disrupts normal cellular function, effectively immobilizing and killing the parasite.
Indications / Uses
Ivermectin is primarily approved for treating parasitic infections such as:
- Onchocerciasis: Commonly known as river blindness, caused by the Onchocerca volvulus worm.
- Lymphatic Filariasis: Caused by infection with filarial worms such as Wuchereria bancrofti.
- Strongyloidiasis: An intestinal infection caused by the roundworm Strongyloides stercoralis.
- Scabies: Although primarily used for mite infestations like scabies off-label.
Off-label uses should always be overseen by a healthcare professional to ensure safety and efficacy.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available primarily as oral tablets. The dosing of ivermectin tablets is highly dependent on the type of parasitic infection being treated, the weight of the patient, and other individual factors.
- Formulation: Generally available in tablet form for human use.
