What It Is and How It Works
Ivermectin belongs to a class of drugs known as antiparasitics. It is used to treat infections caused by certain parasites by binding to glutamate-gated chloride ion channels, which are present in the nerve and muscle cells of these organisms. This binding stimulates an increase in the permeability of the cell membrane to chloride ions, resulting in paralysis and death of the parasites.
Indications / Uses
Primarily, ivermectin is used for treating a range of parasitic infections such as strongyloidiasis and onchocerciasis in humans. In some cases, it is used off-label under a doctor’s supervision for scabies and head lice. It has also been researched in various unapproved scenarios, although further scientific validation is needed.
Dosage Forms and Typical Dosing Considerations
Ivermectin is commonly available in oral tablet form, typically at 3mg per tablet. The typical dosage depends on the type of infection being treated and the patient\’s weight, which is often calculated as a total dose in micrograms per kilogram of body weight. Factors like liver function, pregnancy status, and potential drug interactions must be considered by a healthcare provider to determine the appropriate dose.
