Abstract: This invention provides a novel pharmaceutical composition exhibiting remarkable anti-cancer, and cancer necrotizing properties as well as other desirable pharmacological properties. The composition is a mixture of toluene sulfonamide (e.g. para toluene sulfonamide) with a specifically designed solution which consists of polyethylene glycol, 2-ethyl-1,3-hexanediol, propanediol, decanedioic acid, dimethyl, sulfoxide and ethanol. The composition demonstrates promising therapeutical activity in preliminary human clinical tests and exhibits very little undesirable side effects.
