Ivermectin

Key points

• An avermectin-class antiparasitic used for strongyloidiasis, scabies and onchocerciasis, targeting the parasite’s nervous system rather than human cells.
• Binds to chloride channels in parasite nerve and muscle cells, causing paralysis that clears the infestation without harming the host.
• Tablet form requires disclosure of any known allergy to ivermectin or related avermectins, plus liver or kidney history, before use.

What is Ivermectin?

Ivermectin is an antiparasitic agent belonging to the class of medications known as avermectins. It functions by binding to specific channels within the nervous system of parasites, leading to paralysis and eventual elimination. Its primary role involves managing conditions that cause skin irritation or internal distress due to specific worm infestations.

What Ivermectin is used for

This medication is widely utilised for several conditions caused by specific parasitic organisms. It is indicated for the management of Strongyloidiasis, Scabies, and Onchocerciasis. By interrupting the survival mechanisms of these parasites, the treatment addresses the underlying cause of the infestation.

How does Ivermectin work?

The mechanism involves targeting invertebrate-specific glutamate-gated chloride channels in the nerve and muscle cells of the parasite. Once the medication binds to these receptors, it increases the permeability of the cell membrane to chloride ions. This result causes hyperpolarization, leading to the paralysis and death of the parasite, without causing damage to the human host.

Ivermectin forms

Ivermectin is available as a Tablet. This form is standard for systemic treatment, ensuring proper ingestion to allow the medication to reach the bloodstream where it becomes active. Using Antiparasitics in this specific form allows for accurate dosing and straightforward management of the documented conditions.
