Leading by Example


We take giving back very seriously, and in partnership with InSud Pharma, we fulfill our social responsibilities through Mundo Sano, a non-profit foundation whose vision is to transform the lives of populations affected by neglected diseases.

With FDA approval of Benznidazole Tablets for children 2 to 12 years of age in the United States, patients with Chagas disease now have a treatment option where they previously had none. This advance in the fight against Chagas disease is due to our collaboration with InSud Pharma, Mundo Sano, and the Drugs for Neglected Diseases initiative (DNDi).

Benznidozole is the first and only approved antimicrobial for treating Chagas disease in children ages 2 to 12. Chagas is a serious parasitic disease, and we produce this drug for the Mundo Sano Foundation which shares our mission of giving back to society.


Benznidazole Tablets are available in both 12.5 mg and 100 mg strengths.
