What It Is and How It Works
Ivermectin is an antiparasitic agent that belongs to the avermectin class of drugs. It acts by binding to specific receptors in invertebrate nerve and muscle cells, causing paralysis and death of the parasite. In humans, it primarily targets head lice, scabies mites, and the worms responsible for river blindness and other parasitic conditions.
At a more technical level, it increases the permeability of the cell membrane to chloride ions in parasites, leading to hyperpolarization of the cell, followed by paralysis and death. In mammals, ivermectin is well-tolerated because it does not easily cross the blood-brain barrier in adequate quantities.
Indications / Uses
Ivermectin is approved for various parasitic infections:
- Treatment of head lice and scabies.
- Management of onchocerciasis (river blindness) caused by Onchocerca volvulus.
- Treatment of strongyloidiasis caused by Strongyloides stercoralis.
In some regions, ivermectin is used off-label for other parasitic infections. Any off-label usage should be strictly supervised by a healthcare provider, as evidence may vary between countries and guidelines.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in different forms, including:
- Oral tablets for treating systemic parasitic infections.
- Topical creams and lotions for skin surface infestations like head lice and scabies.
General dosing varies based on the type and severity of the infection, patient’s age, weight, and overall health status. Specific dosages are prescribed by healthcare providers, and patients should strictly adhere to these instructions. Conditions such as liver health, pregnancy, or concurrent use of drugs may influence dosing considerations.
