Description
Overview of the medicine
Mesna is a sulfhydryl compound used to prevent hemorrhagic cystitis caused by oxazaphosphorine cytostatics like ifosfamide and cyclophosphamide.
Uses & Indications
Dosage
Adults
Typically, the total daily dose of Mesna is 60% of the ifosfamide or cyclophosphamide dose, divided into three equal bolus injections (20% each) given at 0, 4, and 8 hours after the cytostatic.
Elderly
No specific dosage adjustment based on age alone; consider renal function.
Renal_impairment
No specific dosage adjustment recommended for Mesna itself, but careful monitoring may be advisable due to underlying disease or co-medications.
How to Take
Uromitexan 400 mg Injection is administered intravenously by a healthcare professional. It can be given as a bolus injection or as a continuous infusion. It should be given with appropriate timing relative to the chemotherapy agent.
Mechanism of Action
Mesna binds to and detoxifies urotoxic metabolites, particularly acrolein, produced by oxazaphosphorine cytostatics in the urinary tract, preventing bladder toxicity.
Pharmacokinetics
Onset
Rapid, typically within minutes of intravenous administration.
Excretion
Primarily renal; approximately 60-80% excreted within 24 hours as mesna or dimesna.
Half life
Parent compound (Mesna): approximately 0.36 hours. Mesna-disulfide (dimesna): approximately 1.12 hours.
Absorption
Administered intravenously, resulting in 100% systemic bioavailability. Rapidly oxidized in plasma to dimesna (mesna disulfide), its major circulating metabolite.
Metabolism
Rapidly oxidized in the plasma to dimesna. Dimesna is then reduced back to free mesna in the kidney tubules.
Side Effects
Contraindications
- Hypersensitivity to Mesna or other thiol compounds.
- Known allergic reaction to any component of the formulation.
Drug Interactions
No other significant drug-drug interactions are well-documented.
Mesna's action is localized to the urinary tract.
Oxazaphosphorine cytostatics (e.g., ifosfamide, cyclophosphamide)
Mesna is designed to specifically interact with and detoxify metabolites of these drugs in the urinary tract without interfering with their anti-cancer efficacy.
Storage
Store at room temperature (20-25°C or 68-77°F). Protect from light. Do not freeze. Discard any unused portion.
Overdose
No specific antidote for Mesna overdose. Management involves supportive care and symptomatic treatment.
Pregnancy & Lactation
Pregnancy Category B. Use in pregnancy only if clearly needed and the potential benefits outweigh the risks. It is unknown if Mesna is excreted in human milk; caution should be exercised when administered to a nursing woman.

YesClinical Trials
Mesna's efficacy and safety in preventing oxazaphosphorine-induced hemorrhagic cystitis have been established through extensive clinical trials since its introduction.
Lab Monitoring
- Regular urinalysis for hematuria (blood in urine) is essential during oxazaphosphorine chemotherapy.
- Renal function tests (e.g., creatinine, BUN) should be monitored.
- Complete blood count (CBC) as part of the overall chemotherapy regimen monitoring.
Doctor Notes
- Ensure adequate hydration of the patient before, during, and after administration of ifosfamide or high-dose cyclophosphamide.
- Monitor urine for hematuria using dipstick tests or microscopic examination during the entire course of oxazaphosphorine therapy.
- Mesna does not prevent nephrotoxicity or other non-bladder toxicities of oxazaphosphorine agents.
Patient Guidelines
- It is crucial to follow the prescribed dosage and schedule precisely, as Mesna's protective effect is time-dependent.
- Report any unusual symptoms, especially urinary symptoms or allergic reactions, immediately to your healthcare provider.
- Maintain adequate hydration by drinking plenty of fluids as advised by your doctor.
Missed Dose Advice
If a dose of Mesna is missed, it is critical to inform the prescribing physician or healthcare professional immediately, as timely administration is essential for adequate uroprotection with chemotherapy.
Driving Precautions
Mesna may cause dizziness or fatigue. Patients should be cautioned about driving or operating machinery if they experience these symptoms.
Lifestyle Advice
- Maintain good hydration throughout the chemotherapy treatment period to support kidney function and Mesna's uroprotective effect.
