Arsthinol (INN) is an antiprotozoal agent. It was synthesized for the first time in 1949 by Ernst A.H. Friedheim by complexation of acetarsol with 2,3-dimercaptopropanol (British anti-Lewisite)[2] and has been demonstrated to be effective against amoebiasis and yaws. It was marketed few years latter by Endo Products (Balarsen, Tablets, 0.1 g).[3] Among trivalent organoarsenicals, arthinol was considered as very well tolerated.[4] Recently, it was studied for its anticancer activity.[5][6]
