What It Is and How It Works
Ivermectin is an antiparasitic agent that is widely used in the treatment of infections caused by various parasites. Its mechanism of action involves binding to specific channels within the nerve and muscle cells of the parasite, leading to paralysis and death of the organism.
This action primarily affects parasites and does not significantly harm humans when used appropriately, as these channels are specific to invertebrates.
Indications / Uses
Ivermectin is approved for several uses in humans, primarily targeting parasitic infections. Key approved uses include:
- Treatment of infections caused by roundworms, such as onchocerciasis (river blindness) and intestinal strongyloidiasis.
- Control of infections like scabies and head lice when alternative treatments are not available or appropriate.
Off-label use of ivermectin has been explored in various conditions, though such use should be guided by a healthcare professional due to limited evidence in many cases.
Dosage Forms and Typical Dosing Considerations
Ivermectin is available in several forms:
- Oral tablets: Commonly used for systemic infections.
- Topical products: Creams and lotions for conditions like scabies and head lice.
Dosing is generally based on body weight, type of infection, and individual patient considerations such as liver function and potential drug interactions. Pediatric and elderly patients require careful dosing by a healthcare professional.
