Product Description

sigma banner.jpgV2-Product Profile

Pyrimethamine (Daraprim) is a medication used for protozoal infections. It is commonly used as an antimalarial drug (for both treatment and prevention of malaria), and is also used (combined with sulfadiazine) in the treatment of Toxoplasma gondii infections in immunocompromised patients, such as HIV-positive individuals. It is also currently being evaluated in clinical trials as a treatment for ALS. In 2011, researchers have discovered that Pyrimethamine can increase ß-hexosaminidase activity, thus slowing down the progression of Late-Onset Tay-Sachs disease.
