What It Is and How It Works
Ivermectin is an anti-parasitic agent that belongs to a class of drugs known as avermectins. It works by binding to invertebrate muscle and nerve cells, causing paralysis and death of the parasites. This makes it highly effective against a range of parasitic infections such as river blindness (onchocerciasis) and strongyloides.
In technical terms, ivermectin enhances the release of gamma-aminobutyric acid (GABA) at presynaptic neurons in the parasite, leading to an inhibitory effect on neurotransmission.
Indications / Uses
Ivermectin is primarily approved for the treatment of several parasitic infections including:
- Onchocerciasis (river blindness)
- Strongyloidiasis, a roundworm infection
- Head lice and scabies
There have been discussions about ivermectin being used in treating viral infections, but such uses are considered experimental and should be pursued only under clinical supervision.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in various forms including oral tablets, topical formulations, and injectable forms. The oral form is most commonly used for human parasitic infections. Dosage depends on the type of infection, the patient\’s weight, and overall health condition. It\’s crucial to follow the dosing instructions provided by a healthcare provider.
Dosing considerations include factors such as age, kidney and liver function, pregnancy status, and interaction with other medications. Patients should not self-adjust their dosage without professional guidance.
