Ibuprofen (Arginine) Normon (Ibuprofen)

Ibuprofen acts as an NSAID that reduces inflammation and pain through cyclo‑oxygenase inhibition. It is commonly employed for:

• Pain: provides relief from mild to moderate musculoskeletal and dental pain.
• Fever: lowers elevated body temperature associated with infections or inflammatory conditions.
• Inflammation: diminishes swelling in conditions such as arthritis or soft‑tissue injuries.

• Ibuprofen inhibits both cyclo‑oxygenase‑1 (COX‑1) and cyclo‑oxygenase‑2 (COX‑2) enzymes, which reduces the conversion of arachidonic acid to prostaglandins. Lower prostaglandin levels decrease inflammation, pain signaling, and fever generation, providing symptomatic relief across a range of acute and chronic conditions.

Adverse reactions may vary in frequency and severity.

Common Side Effects

• Nausea: mild stomach upset that often resolves with food.
• Dyspepsia: discomfort or burning in the upper abdomen.
• Headache: transient tension‑type headache.
• Dizziness: occasional light‑headed sensation.
• Rash: mild skin irritation or redness.
• Diarrhoea: loose stools that are usually self‑limiting.

Serious or Rare Side Effects

• Gastrointestinal bleeding: visible blood in stool or vomit.
• Peptic ulcer perforation: severe abdominal pain requiring urgent care.
• Renal impairment: reduced urine output or swelling.
• Severe allergic reaction: swelling of face, lips, or throat, and difficulty breathing.
• Hepatic injury: jaundice or abnormal liver tests.
• Cardiovascular events: increased risk of heart attack or stroke in susceptible individuals.

Before using ibuprofen, consider the following safety measures:

• Assess gastrointestinal risk: avoid in patients with active ulcers or a history of GI bleeding.
• Monitor renal function: use caution in those with kidney disease or dehydration.
• Use lowest effective dose: limit duration to the shortest period needed for symptom control.
• Avoid in third trimester: ibuprofen may affect fetal cardiovascular development.
• Review concomitant medications: check for other NSAIDs or anticoagulants.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Ibuprofen can interact with several drug classes, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of serious bleeding.
• Other NSAIDs or aspirin: heightened gastrointestinal toxicity.
• Corticosteroids: additive risk of ulceration and bleeding.
• ACE inhibitors or ARBs: may reduce renal perfusion and function.
• Lithium: ibuprofen can raise lithium serum levels, risking toxicity.

Moderate Interactions (Monitor Closely):\n- Antihypertensives (e.g., beta‑blockers): may blunt blood‑pressure‑lowering effect.

• Diuretics: potential for reduced renal clearance.
• Methotrexate: decreased elimination leading to toxicity.
• SSRIs (e.g., sertraline): modest increase in bleeding risk.
• Diabetic agents: possible alteration of glycemic control.
