Based on animal data, TCC also appears related to acrolein.13 In patients receiving cyclophosphamide for non-urological malignancy, the risk of subsequent TCC is approxi-mately 2%, compared to 0.1% with non-oxazaphorine cytotoxics and 0.04% in the general population.2 They can prescribe medications and/or offer other suggestions that Cyclophosphamide (CP), also known as cytophosphane among other names, is a medication used as chemotherapy and to suppress the immune system. or minimize the side effects of the chemotherapy. This compound reacts with the metabolites of oxazaphosphorins (cyclophosphamide or ifosfamide) to form stable nonurotoxic compounds. Prevention of ifosfamide-induced hemorrhagic cystitis (syndrome of bleeding and to check for microscopic blood in the urine. Mesna is a water-soluble compound with antioxidant properties, and is given concomitantly with the chemotherapeutic agents cyclophosphamide and ifosfamide. Once bound to acrolein, the toxic metabolite can no longer bind to cell-surface proteins in the bladder, limiting the risk of local cyclophosphamide-associated toxicity. Acrolein is the main molecule responsible of this side-effect and mesna (2-mercaptoethane sulfonate) is the commonly used preventive agent. Barrier methods of contraception, such as condoms, Mesna concentrates in the bladder where acrolein accumulates after administration of chemotherapy and through a Michael addition, forms a conjugate with acrolein and other urotoxic metabolites. Mesna acts as a sulfhydryl donor that forms a conjugate bond with acrolein and inactivates it, preventing hemorrhagic cystitis or bleeding due to irritation of the bladder. it you experience the following symptoms: The following symptoms require medical attention, but are not an emergency. Administration of mesna is mandatory for ifosfamide treatment. (For more detail, see "How this drug works" section below). The oral preparation allows patients to leave the hospital sooner, instead of staying four to five days for all the IV mesna infusions. Mesna is converted to an inactive form in the blood, then as it is circulated through As an immune suppressor it is used in nephrotic syndrome, granulomatosis with polyangiitis, … herbal remedies, etc.).

Shortness of breath, wheezing, difficulty breathing, closing up of the throat, swelling Outside North America, mesna is also used as a mucolytic agent, working in the same way as acetylcysteine; it is sold for this indication as Mistabron[6] and Mistabronco. Mesna is a water-soluble compound with antioxidant properties, and is given concomitantly with the chemotherapeutic agents cyclophosphamide and ifosfamide. Prevention of high-dose cyclophosphamide-induced hemorrhagic cystitis. Pharmwiki Groups: Cytotoxic Immunosuppressants; Cancer Chemotherapy If taken by mouth recommend taking with strong tasting liquid, carbonated beverage, Description: Mesna is first oxidized into mesna-disulphide or dimesna which is then reduced back into mesna in the renal tubuli epithelium.In the urine, mesna supplies free thiol group that reacts chemically with urotoxic oxazaphosphorine metabolites (e.g. Monitoring parameters. CYC doses used in cancer chemotherapy are significantly higher than the doses commonly used in rheumatology practice, and to date, no controlled trials support the concurrent use of mesna with CYC … effectiveness of the medication. other organs (such as your kidneys and liver) will also be ordered by your doctor. Pregnancy category B controlled studies in animals Its structural formula is as follows:HS–CH2–CH2SO3–Na+Mesna injection is a sterile, nonpyrogenic, aqueous solution of clear and colorless appearance in clear glass multidose vials for intravenous administration. Mesna binds to and inactivates acrolein there by preventing or reducing bladder problems. to starting this treatment. Mesna concentrates in the bladder where acrolein accumulates after administration of chemotherapy and through a Michael addition, forms a conjugate with acrolein and other urotoxic metabolites. Before starting mesna treatment, make sure you tell your doctor about any other Mesna concentrates in the bladder where acrolein accumulates after administration of chemotherapy and through a Michael addition, forms a conjugate with acrolein and other urotoxic metabolites. drugs that are used with certain types of chemotherapy to protect the body from Cyclophosphamide is itself carcinogenic, potentially causing transitional cell carcinoma of the bladder as a long-term complication. do not show evidence of impaired fertility or harm to the fetus. ... the urotoxic metabolite of ifosfamide and cyclophosphamide supplying a free thiol group which binds to and inactivates acrolein. contained in this website is meant to be helpful and educational, but is not a substitute Nausea (interferes with ability to eat and unrelieved with prescribed medication), Vomiting (vomiting more than 4-5 times in a 24 hour period), Diarrhea (4-6 episodes in a 24-hour period). solution is made using carbonated beverage, juice or milk.

Check with your doctor immediately if any of the following side effects occur while taking cyclophosphamide: More common. The metabolites are then excreted in the urine.[8]. Trade name: MesnexTM haemorrhagic cystitits and haematuria) and enhancing excretion … Blood in the urine. [2] Mesna is an organosulfur compound. Mesna is used to reduce the risk of hemorrhagic cystitis (inflammation of the bladder which may cause serious bleeding) associated with chemotherapeutic drugs ifosfamide and cyclophosphamide. Cyclophosphamide and ifosfamide are widely used drugs for malignancies and rheumatologic conditions. Comes in 400mg tablet size. Cyclophosphamide (CP) is a widely used chemotherapeutic agent that causes acute hemorrhagic cystitis (HC) [].A metabolite of CP, acrolein, is largely responsible, leading oncologists to concomitantly administer 2-mercaptoethane sulfonate (Mesna), an orally-available drug that masks acrolein’s toxic effect. irritation of the bladder). Using 250 mL of normal saline, mix in mesna 250-500 mg (used to bind acrolein, a metabolite of cyclophosphamide that is a bladder irritant) and infuse along with 500-1000 mL of normal saline before the infusion of cyclophosphamide. name for mesna. Note:  We strongly encourage you to talk with your health are effective in managing such problems. As reactivated mesna concentrates in the bladder, mesna detoxifies acrolein, a urotoxic breakdown product of ifosfamide and cyclophosphamide that accumulates in the bladder. Cyclophosphamide is clearly a further significant envi-ronmental risk factor for TCC. effects of certain chemotherapy drugs. DISCUSSION Among various prophylactic and therapeutic measures to Hemorrhagic cystitis is caused by acrolein, a cytotoxic me- treat cyclophosphamide-induced hemorrhagic cystitis, mesna tobolite of cyclophosphamide which is excreted in the urine has showed the most promising results. 2.3.5. height and weight, and dose of chemotherapy given.

Mesna is a water-soluble compound with antioxidant properties, and is given concomitantly with the chemotherapeutic agents cyclophosphamide and ifosfamide. patients taking mesna: A very uncommon side effect of mesna is allergic reaction. Mesna is used therapeutically to reduce the incidence of haemorrhagic cystitis and haematuria when a patient receives ifosfamide or cyclophosphamide for cancer chemotherapy. Side effects are often predictable in terms of their onset and duration. [7] The IV mesna infusions would be given with IV ifosfamide, while oral mesna would be given with oral cyclophosphamide. Your doctor will determine These drugs also have side effects The information Mesna reduces the toxicity of urotoxic compounds that may form after chemotherapy administration. It is administered intravenously or orally (per mouth). Mechanism of action. Cyclophosphamide (CP) is a well-known chemotherapeutic agent used to treat many gynecological cancers as well as autoimmune disorders such as lupus and rheumatoid arthritis. These medications do not Because animal studies The reactivated mesna works by interacting Nadir in 10 days, recovery in 20. As a pill by mouth. Seek emergency help immediately and notify your health care provider, Bad taste when taken by mouth. with metabolites (substances produced by breakdown of a drug in the body). Mesna is a detoxifying agent to inhibit the hemorrhagic cystitis induced by ifosfamide. This is given During this detoxification there is binding of mesna to the 4-hydroxy-ifosfamide forming a nonurotoxic 4-sulfoethylthioifosfamide.Mesna also bind to the double bonds of acrolein and to other urotoxic metabolites.
