CLINICAL USE <\/H3>
\nProphylaxis of urothelial toxicity in patients treated with ifosfamide or cyclophosphamide

    ADMINISTRATION <\/H3>

    Reconstition<\/H4>\u2013

    Route <\/H4>Oral, IV bolus,

    IV infusion <\/H4>

    Rate of Administration <\/H4>IV bolus: over 15\u201330 minutes

    IV infusion <\/H4>: over 12\u201324 hours

    Comments<\/H4>Compatible with sodium chloride 0.9% and glucose 5%Mesna injection can be administered orally in orange juice or cola to improve palatability

    OTHER INFORMATION <\/H4>Urinary output should be maintained at 100 mL\/hr (as required for oxazaphosphorine treatment)The dose of mesna is dependent on the dose of oxazaphosphorine, e.g. reduce dose of cyclophosphamide to 50% of normal if GFR
  • <10 &nbsp &nbsp &nbsp &nbsp &nbsp : mL\/min; hence, dose of mesna will consequently be reducedFrom what is known about the pharmacokinetics and mechanism of action of mesna, its availability in the urinary tract depends on renal functionIn the case of completely anuric patients (extremely rare) neither cyclophosphamide nor its metabolites should appear in the urinary tract: the use of mesna concomitantly may therefore be unnecessary in anuric patients. If there is any risk of cyclophosphamide or its metabolites entering the urinary tract, mesna should probably be given to prevent urothelial toxicityLimited kinetic information would suggest mesna would be eliminated by haemodialysis.
