Ivermectin is an anti-parasite medication that is used to treat various parasitic infections, including river blindness, threadworm infections, filarial worm infections (such as lymphatic filariasis or microfilaremia), hookworm infections, scabies, lice infestations, and helminthiasis (like roundworms, whipworms, and pinworms). It belongs to the class of drugs known as anthelmintics.

River blindness also called onchocerciasis, is a type of parasitic worm infection that affects the skin, lymph nodes, and eyes, causing symptoms like rash, itching, bumps under the skin, enlarged glands in the neck, armpits, and groin, and painful or blind eyes.

Threadworm infections, or intestinal strongyloidiasis, affect the skin and intestines and cause symptoms like rash, itching, stomach pain, vomiting, and diarrhea.

 Lymphatic filariasis is a parasitic infection caused by certain types of worms that affects the lymph nodes and vessels in the body. Microfilaremia is a type of filarial infection that involves the presence of microfilariae, which are baby worms, in the blood. Both lymphatic filariasis and microfilaremia can cause symptoms such as swelling in the limbs, fever, and tiredness.

Scabies is a contagious skin infection caused by a type of mite called Sarcoptes scabiei. It is spread through direct skin-to-skin contact, including sexual contact, and can also be transmitted through contact with infected clothing or furnishings. Scabies causes intense itching, especially at night, and can result in the development of blisters or lumps on the skin, particularly in areas such as the fingers, underarms, breasts, penis, buttocks, scalp, palms, and soles.

What does Ivermectin do?

It works by specifically targeting the glutamate-gated chloride ion channels found in the nerve and muscle cells of the parasites. When ivermectin binds to these channels, it causes an influx of chloride ions, leading to hyperpolarization of the cells. This results in paralysis and, death of the parasite. Ivermectin is effective against a variety of parasites and is used to treat infections such as river blindness, threadworm infections, filarial worm infections, hookworm infections, scabies, lice infestations, and helminthiasis.
