Levamisole is an anthelmintic with immunomodulatory properties. It is a synthetic derivative of the natural compound tetramisole. Levamisole is primarily used to treat helminth infections in animals and has also been used in the past to treat certain diseases in humans. However, its human use has decreased over time due to potential side effects and the availability of other treatment options.

Chemically, levamisole is known as (S)-2,3,5,6-tetrahydro-6-phenylimidazo[2,1-b]thiazole. It is supplied as a racemic mixture, which means it contains both the (S)- and (R)-enantiomers. Levamisole is usually supplied as levamisole hydrochloride, combined with hydrochloric acid to enhance its stability and solubility.


Medical Uses:

Anthelmintic Agent: Levamisole is primarily used as an anthelmintic drug to treat parasitic worm infections in animals. It works by paralyzing and killing the worms, making it easier for the host to eliminate them from the body. It is effective against gastrointestinal nematodes and lungworms in livestock.

Immunomodulatory Agent: Levamisole has interesting immunomodulatory properties, and it can stimulate certain components of the immune system, such as T-cells. As a result, it has been used as an adjuvant treatment for some immune system disorders in the past.

Previous Human Uses:

Levamisole was previously used in human medicine for certain conditions, but its use has declined due to safety concerns and alternative treatments. In the past, it was used for the following medical purposes:

Treatment of Certain Worm Infections: Levamisole was used to treat certain worm infestations in humans, such as hookworm and roundworm infections.

Immune System Disorders: Levamisole was used as an adjuvant treatment for some immune system disorders, such as rheumatoid arthritis and certain types of cancer. It was thought to enhance the body's immune response in these conditions.

Today, levamisole is rarely prescribed for human use and is mainly reserved for veterinary medicine to treat worm infestations in animals.

As with all medications, levamisole should be used under the guidance of a qualified healthcare professional or veterinarian. Proper dosing and safety precautions should be followed to avoid potential adverse effects or interactions with other medications. Additionally, the use of levamisole in humans should be limited to situations where other treatments have been deemed ineffective or are not available.
