Indications & Clinical Uses

Mezavant (mesalazine) is used to manage inflammatory conditions of the colon, primarily ulcerative colitis.

  • Ulcerative colitis (induction): reduces mucosal inflammation to induce remission in active disease.
  • Ulcerative colitis (maintenance): helps sustain remission and prevent relapse.
  • Mild to moderate ulcerative colitis: provides topical anti‑inflammatory effect throughout the colon.

How It Works

  • Mesalazine exerts its anti‑inflammatory action locally in the intestinal lumen by inhibiting cyclooxygenase and lipoxygenase pathways, which lowers prostaglandin and leukotriene synthesis. It also scavenges free radicals, thereby reducing oxidative stress and dampening the inflammatory response of the colonic mucosa.

Side Effects

Adverse reactions may occur with mesalazine therapy. Most are mild and reversible, but serious events are reported in a minority of patients.

Common Side Effects

  • Nausea
  • Abdominal pain
  • Headache
  • Flatulence

Serious or Rare Side Effects

  • Severe allergic reaction (anaphylaxis)
  • Myocarditis
  • Pancreatitis

Precautions & Warnings

Before initiating Mezavant, clinicians should evaluate patient-specific risk factors and monitor for potential complications.

  • Renal function: assess baseline and monitor periodically for renal impairment.
  • Hepatic function: check liver enzymes before treatment and during therapy.
  • Disease activity: ensure active ulcerative colitis is appropriately diagnosed.
  • Hypersensitivity: avoid in patients with known allergy to mesalazine or related compounds.
  • Sulfonamide sensitivity: use caution in patients with sulfonamide intolerance.
  • Store at ambient temperature: keep in the original container, protect from moisture.

Avoid Interactions

Mesalazine can interact with several medicines, requiring attention to avoid reduced efficacy or increased toxicity.

Major Interactions (Avoid)

  • Azathioprine: may increase risk of bone marrow suppression.
  • Warfarin: can enhance anticoagulant effect, raising bleeding risk.
  • Methotrexate: potential for additive toxicity.

Moderate Interactions (Monitor Closely)

  • Oral contraceptives: may reduce hormonal efficacy.
  • NSAIDs: increase gastrointestinal irritation.
  • Lithium: possible alteration of serum lithium levels.

Frequently Asked Questions

Mezavant contains mesalazine, a 5‑aminosalicylic acid that is prescribed to treat ulcerative colitis. It helps reduce inflammation in the colon, facilitating induction of remission during active disease and supporting maintenance of remission over the long term.

Mesalazine acts locally in the intestinal lumen, inhibiting cyclooxygenase and lipoxygenase enzymes, which lowers prostaglandin and leukotriene production. It also scavenges free radicals, thereby decreasing oxidative stress and dampening the inflammatory response of the colonic mucosa.

The specific dose of Mezavant is determined by the prescribing clinician based on disease severity, patient weight, and response to therapy. Healthcare professionals tailor the regimen to each individual, and patients should follow the prescriber’s instructions without alteration.

Safety data for mesalazine in pregnancy and lactation are limited. Clinicians weigh potential benefits against risks before prescribing to pregnant or nursing women. Patients should discuss their situation with a healthcare provider to decide whether the medication is appropriate.

To request Mezavant, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Mezavant belongs to the 5‑ASA class, offering a topical anti‑inflammatory effect within the colon. Compared with systemic steroids, it has a more favorable safety profile for long‑term use. Biologic agents target immune pathways but are generally reserved for moderate‑to‑severe disease when 5‑ASA therapy is insufficient.

Mezavant should be stored at ambient temperature, below 25 °C, in its original packaging to protect it from moisture and light. Keep the product out of reach of children and avoid storing it in bathrooms or other humid environments.

Mezavant is taken orally, usually with water. The tablet (or other oral form) should be swallowed whole unless the prescribing information advises otherwise. Patients should follow the dosing schedule provided by their healthcare professional and not crush or split the tablet without guidance.

Serious adverse events, though uncommon, include severe allergic reactions such as anaphylaxis, myocarditis, and pancreatitis. Patients should seek immediate medical attention if they experience symptoms like difficulty breathing, chest pain, severe abdominal pain, or persistent vomiting.

Mezavant is contraindicated in individuals with known hypersensitivity to mesalazine, other 5‑ASA compounds, or any excipients in the formulation. It should also be avoided in patients with severe renal or hepatic impairment unless closely monitored by a specialist.
