What is Mesna
Mesna (sodium 2-mercaptoethanesulfonate) is a chemoprotectant that protects against hemorrhagic cystitis from ifosfamide and other oxazaphosphorine chemotherapy agents (e.g., cyclophosphamide).
Chemoprotectants differ from other rescue medications such as hematopoietic rescue with colony-stimulating factors or replacement therapy with leucovorin in that they are administered prior to the chemotherapy to prevent toxicities.
Mesna provides more effective urinary prophylaxis of hemorrhagic cystitis than other regimens consisting of fluids, administration of diuretics and forced diuresis, and intravesical administration of other sulfhydryl-compounds such as N-acetylcysteine.
Mesna is a superior uroprotectant agent as compared to other sulfhydryl compounds because it remains in the intravascular fluid, is concentrated in the bladder, and is less likely to be absorbed by tumor cells.
Mesna does not interfere with the antitumor activity of ifosfamide or cyclophosphamide. Mesna is indicated as a prophylaxis agent to reduce the incidence of ifosfamide-induced hemorrhagic cystitis.
The FDA approved mesna injection in 1988 and mesna tablets in March 2002.
