Ibuprofen Pharmaclan (Ibuprofen)

Ibuprofen acts on the prostaglandin pathway to provide symptomatic relief in several common conditions.

• Pain: Reduces mild to moderate nociceptive pain such as headaches, dental pain, or musculoskeletal aches.
• Fever: Lowers elevated body temperature associated with infections or inflammatory processes.
• Inflammation: Decreases swelling and discomfort in conditions like arthritis or soft‑tissue injuries.

• Ibuprofen exerts its effect by reversibly inhibiting cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, which are essential for the conversion of arachidonic acid to prostaglandins. By decreasing prostaglandin synthesis, it reduces inflammation, pain signaling, and the hypothalamic set‑point for temperature regulation, providing analgesic, antipyretic, and anti‑inflammatory actions.

Ibuprofen may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects

• Gastrointestinal discomfort: nausea, dyspepsia, or abdominal pain.
• Headache: mild to moderate tension‑type headache.
• Dizziness: transient light‑headedness or vertigo.
• Rash: mild skin erythema or itching.

Serious or Rare Side Effects

• Gastrointestinal bleeding: ulceration or hemorrhage in the stomach or intestines.
• Renal impairment: reduced kidney function or acute kidney injury.
• Cardiovascular events: increased risk of heart attack or stroke, especially with high‑dose or prolonged use.
• Severe allergic reaction: anaphylaxis, angioedema, or bronchospasm.

When considering ibuprofen therapy, several precautions should be observed to minimize risk.

• Assess renal function: avoid use in patients with severe kidney disease or dehydration.
• Evaluate cardiovascular risk: use cautiously in individuals with hypertension, heart failure, or prior thrombotic events.
• Monitor gastrointestinal history: avoid in patients with active ulcers or a history of serious GI bleeding.
• Consider pregnancy status: discuss potential risks with a healthcare professional before use during pregnancy.
• Review concomitant medications: check for drugs that may increase bleeding or renal toxicity.
• Store at ambient temperature: keep below 25 °C in the original packaging, protected from moisture and direct sunlight.

Ibuprofen can interact with other medicines, altering efficacy or safety.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of serious bleeding.
• High‑dose aspirin: enhanced gastrointestinal toxicity.
• Selective COX‑2 inhibitors: additive renal and cardiovascular adverse effects.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: may reduce antihypertensive effect and impair renal function.
• Diuretics: potential for decreased kidney perfusion.
• Lithium: ibuprofen can raise serum lithium levels, risking toxicity.
• Methotrexate: reduced clearance leading to toxicity.
