Ibuprofen Pharmaclan (Ibuprofen)

Ibuprofen is an NSAID that reduces inflammation and pain by inhibiting cyclooxygenase enzymes.

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

• Ibuprofen exerts its effect by reversibly inhibiting both cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes. This blockade reduces the conversion of arachidonic acid to prostaglandins and thromboxanes, mediators that promote inflammation, pain perception, and fever. By lowering prostaglandin levels in peripheral tissues and the central nervous system, ibuprofen diminishes nociceptive signaling and thermoregulatory responses. The inhibition is dose‑dependent and reversible, allowing normal prostaglandin synthesis to resume after the drug is cleared.

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

Common Side Effects

• Gastrointestinal upset: Nausea, dyspepsia, abdominal discomfort or mild heartburn that usually resolves after discontinuation.
• Headache: Mild to moderate headache that may improve with hydration or analgesic adjustment.
• Dizziness: Transient feeling of light‑headedness or vertigo, often occurring shortly after dosing.
• Rash: Minor skin erythema, itching or urticaria that typically subsides without intervention.

Serious or Rare Side Effects

• Gastrointestinal bleeding or ulceration: Potential for serious bleeding, perforation or ulcer formation in the stomach or intestines, requiring medical attention.
• Renal impairment: Acute kidney injury or reduced renal function, especially in patients with dehydration, pre‑existing kidney disease, or high‑dose therapy.
• Severe allergic reaction: Anaphylaxis, angioedema, or Stevens‑Johnson syndrome presenting with swelling, breathing difficulty or widespread skin lesions.
• Liver enzyme elevation: Significant increase in transaminases indicating hepatic stress, which may necessitate monitoring or discontinuation.

When using ibuprofen, several precautions should be observed to minimize risk and ensure safe therapy.

• Assess gastrointestinal risk: Evaluate history of ulcers, bleeding or concurrent NSAID use before initiating therapy.
• Use lowest effective dose: Prescribe the minimal dose needed for symptom control and limit duration.
• Monitor renal function: Check kidney parameters in patients with pre‑existing renal disease or dehydration.
• Avoid in known hypersensitivity: Do not administer to individuals with documented allergy to ibuprofen or other NSAIDs.
• Caution in cardiovascular disease: Use carefully in patients with hypertension, heart failure or coronary artery disease.
• Store at room temperature: Keep tablets in the original container, protect from moisture and excessive heat.

Ibuprofen can interact with several medicines, altering efficacy or increasing toxicity.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): Increases risk of serious bleeding.
• Lithium: May raise lithium serum levels, leading to toxicity.
• Methotrexate: Enhances methotrexate toxicity, especially at high doses.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: May reduce antihypertensive effect and impair renal function.
• SSRIs or SNRIs: Combined use can elevate bleeding risk.
• Diuretics: May potentiate renal adverse effects, requiring monitoring of kidney function.
