What It Is and How It Works
Ivermectin is an antiparasitic medication that belongs to the class of drugs known as antiparasitic agents. It works by binding to invertebrate nerve and muscle cells, causing paralysis and eventual death of the parasites it targets. This mechanism is particularly effective against a variety of parasitic infections, including those caused by worms and lice.
The drug specifically targets the gamma-aminobutyric acid (GABA) receptors and glutamate-gated chloride ion channels in parasites. Its action disrupts neural and muscular activities critical for their survival, making ivermectin effective in treating infections.
Indications / Uses
Ivermectin is primarily used to treat infections caused by parasites, such as:
- Onchocerciasis (river blindness) caused by Onchocerca volvulus.
- Intestinal strongyloidiasis.
- Scabies and pediculosis (head lice).
- Certain off-label use includes treatment of other parasitic infections under clinician supervision.
Ivermectin is not suitable for viral infections like the common cold or flu and should not be used for these conditions.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms:
- Oral tablets: Mainly used for human ingestion to treat parasitic infections.
- Topical formulations: Used for skin conditions like scabies or lice.
- Injectable forms: Usually reserved for veterinary use or special medical circumstances.
Dosage is determined by weight and the severity of the infection. It\'s critical to follow the dosing instructions provided by a healthcare professional. Specialized dosing guidelines exist for individuals with liver or kidney issues, and adjustments may be necessary for pediatric and elderly patients.
