Mesalazin Orion

Mesalazine, the active ingredient in Mesalazin Orion, is a 5‑aminosalicylic acid (5‑ASA) presented as a rectal formulation for local use in the colon. It is employed to reduce inflammation associated with ulcerative colitis and other inflammatory bowel conditions in adult patients.

GNH USA supplies Mesalazin Orion as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Mesalazin Orion is a 5‑ASA drug used to manage inflammatory bowel disease by targeting colonic inflammation. - Ulcerative colitis: induces remission and reduces disease activity in mild to moderate cases. - Maintenance of remission in ulcerative colitis: helps sustain symptom‑free periods after induction therapy. - Pouchitis: alleviates inflammation in the ileal pouch following colectomy.

Mesalazin Orion may cause a range of adverse reactions, from mild to serious.

Common Side Effects: - Abdominal pain: discomfort or cramping in the lower abdomen. - Nausea: feeling of sickness or urge to vomit. - Headache: mild to moderate pain in the head. - Flatulence: increased intestinal gas. - Rectal irritation: burning or itching at the site of administration.

Serious or Rare Side Effects: - Allergic reaction: rash, swelling, or difficulty breathing. - Severe colitis: worsening inflammation requiring medical attention. - Blood in stool: visible bleeding indicating mucosal injury. - Liver enzyme elevation: abnormal liver function tests. - Pancreatitis: inflammation of the pancreas presenting with abdominal pain and nausea.

Before initiating therapy with Mesalazin Orion, consider the following safety measures. - Renal function assessment: evaluate kidney health, especially in patients with pre‑existing impairment. - Hypersensitivity monitoring: watch for signs of allergic reactions during treatment. - Disease severity evaluation: ensure appropriate use based on ulcerative colitis activity. - Salicylate allergy avoidance: do not prescribe to patients with known hypersensitivity to aspirin or other salicylates. - Pregnancy considerations: use only if potential benefits outweigh unknown risks. - Store at room temperature: keep in the original packaging, protect from moisture and direct sunlight.
