Indications & Clinical Uses

  • Mesalazine acts locally in the gastrointestinal tract to reduce inflammation associated with inflammatory bowel disease.
  • Ulcerative colitis: induces remission and maintains symptom control by decreasing mucosal inflammation.
  • Crohn's disease: helps control intestinal inflammation, reducing abdominal pain and diarrhea.
  • Maintenance therapy for ulcerative colitis: provides ongoing anti‑inflammatory effect to prevent disease flare‑ups.

How It Works

  • Mesalazine exerts its effect by inhibiting cyclooxygenase and lipoxygenase enzymes in the intestinal mucosa, which reduces the synthesis of prostaglandins and leukotrienes. This local inhibition diminishes inflammatory cell activation and cytokine release, leading to decreased mucosal inflammation without significant systemic absorption. The drug is released in the colon where it achieves high local concentrations, allowing targeted action while minimizing systemic exposure.

Side Effects

Mesalazine may be associated with a range of adverse reactions, varying from mild to severe.

Common Side Effects

  • Nausea or upset stomach.
  • Abdominal cramping or pain.
  • Headache.
  • Increased flatulence or gas.

Serious or Rare Side Effects

  • Myocarditis or pericarditis.
  • Severe hypersensitivity reactions such as Stevens‑Johnson syndrome or toxic epidermal necrolysis.

Precautions & Warnings

Before initiating therapy, several safety considerations should be observed.

  • Renal function monitoring: assess serum creatinine before and during therapy.
  • Blood counts: perform periodic complete blood count to detect leukopenia or anemia.
  • Pregnancy and lactation: use only if benefits outweigh risks; consult healthcare provider.
  • Drug hypersensitivity: discontinue if rash, fever, or organ involvement occurs.
  • Store at ambient temperature: keep below 25°C in original packaging, protect from moisture.

Avoid Interactions

Mesalazine can interact with other medicines, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid)

  • Anticoagulants (e.g., warfarin): increased bleeding risk.
  • Azathioprine or 6‑mercaptopurine: may enhance myelosuppression.
  • Non‑steroidal anti‑inflammatory drugs (NSAIDs): additive gastrointestinal toxicity.

Moderate Interactions (Monitor Closely)

  • Oral corticosteroids: may increase risk of infection.
  • Diuretics: may affect renal clearance of mesalazine.

Frequently Asked Questions

Mesalazin Orion contains mesalazine, an Aminosalicylate indicated for the treatment of ulcerative colitis and Crohn's disease. It works by reducing inflammation in the lining of the intestine, helping to induce remission and maintain symptom control in adult patients with inflammatory bowel disease.

Mesalazine inhibits cyclooxygenase and lipoxygenase pathways within the intestinal mucosa, lowering the production of prostaglandins and leukotrienes. This local anti‑inflammatory action reduces activation of inflammatory cells and cytokine release, thereby decreasing mucosal inflammation without substantial systemic absorption.

The appropriate dose of Mesalazin Orion is individualized by the prescribing healthcare professional based on the severity of disease, patient weight, renal function, and response to therapy. Patients should follow the prescriber’s instructions and not adjust the dose on their own.

Safety data for mesalazine in pregnancy and lactation are limited. It should only be used when the potential benefit to the mother outweighs any possible risk to the fetus or infant. Women who are pregnant, planning pregnancy, or breastfeeding should discuss treatment options with their physician.

To request Mesalazin Orion, 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 (including any cold‑chain requirements) and necessary import documentation.

Mesalazin Orion is a locally acting Aminosalicylate, whereas alternatives such as sulfasalazine also contain a sulfapyridine moiety that can cause additional side effects. Biologic agents target systemic immune pathways and are reserved for moderate‑to‑severe disease. Mesalazine is often preferred for mild‑to‑moderate disease because of its targeted action and favorable safety profile.

Store Mesalazin Orion at ambient temperature, preferably below 25 °C. Keep the product in its original container, protect it from moisture and direct sunlight, and ensure the packaging remains sealed until use to maintain product stability.

Mesalazin Orion is taken orally, usually with water. The tablets or capsules should be swallowed whole and not crushed or chewed unless specifically instructed by a healthcare professional. Dosing frequency and timing are determined by the prescriber.

Serious adverse events, although rare, include myocarditis, pericarditis, and severe hypersensitivity reactions such as Stevens‑Johnson syndrome or toxic epidermal necrolysis. Patients should seek immediate medical attention if they experience chest pain, unexplained fever, rash, blistering, or signs of organ involvement.

Mesalazin Orion should be avoided in individuals with known hypersensitivity to mesalazine or any component of the formulation. Caution is also advised for patients with severe renal impairment, active cardiac disease, or those who have previously experienced severe allergic reactions to Aminosalicylates.
