Pharmacological properties

The main active component of the drug is mesna, which is used as a sodium salt, which is two-mercaptoethanesulfonic acid.
It has the ability to reduce nephrotoxicity, as well as the urotoxic activity of drugs that produce an alkylating effect.
Uroprotector, which is able to inactivate the urotoxic effects from the use of drugs such as cyclophosphamides and ifosfamides.
Mesna is capable of rapidly oxidizing, turning into a metabolite of Dimesna. Mesna disulfide is able to remain in the vascular bed, entering the kidneys, where it again becomes a free thiol compound – local. Then this substance, as a result of metabolic and chemical processes, detoxifies urotoxic decay products – metabolites.
Thus, the drug produces a strong cytotoxic effect.
