Ibuprofeno (Arginina) Vir Pharma (Ibuprofen)

Ibuprofen acts systemically to alleviate pain, fever and inflammation associated with a variety of conditions.

• Mild to moderate pain: provides analgesia for headaches, dental pain, musculoskeletal aches, and postoperative discomfort.
• Fever: reduces elevated body temperature in acute febrile illnesses.
• Inflammatory conditions such as arthritis: diminishes joint swelling and stiffness in osteoarthritis and rheumatoid arthritis.

• Ibuprofen reversibly inhibits cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, decreasing the conversion of arachidonic acid to prostaglandins. Lower prostaglandin levels reduce inflammation, pain signaling, and fever generation, producing its therapeutic effects throughout the body.

Adverse reactions may vary in frequency and severity.

Common Side Effects

• Gastrointestinal discomfort: nausea, dyspepsia, or abdominal pain.
• Headache: mild to moderate intensity.
• Dizziness or vertigo.
• Rash or mild skin irritation.
• Elevated blood pressure in some patients.

Serious or Rare Side Effects

• Gastrointestinal bleeding or ulceration.
• Severe allergic reactions: anaphylaxis, angioedema.
• Hepatotoxicity or elevated liver enzymes.
• Renal impairment or acute kidney injury.
• Cardiovascular events: myocardial infarction or stroke, especially with high‑dose or prolonged use.

Before using ibuprofen, consider the following safety measures.

• Assess gastrointestinal risk: avoid in patients with active ulcers or a history of GI bleeding.
• Evaluate cardiovascular status: use cautiously in individuals with hypertension, heart disease, or stroke risk.
• Monitor renal function: limit use in patients with existing kidney disease or dehydration.
• Review concomitant medications: avoid concurrent use with other NSAIDs, anticoagulants, or corticosteroids without medical guidance.
• Pregnancy and lactation: consult a healthcare professional before use during pregnancy or breastfeeding.
• Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

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

Major Interactions (Avoid)

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

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: may reduce antihypertensive efficacy and affect renal function.
• Diuretics: potential for decreased renal perfusion.
• Lithium: ibuprofen can raise serum lithium levels, necessitating monitoring.
• Methotrexate: reduced clearance may increase toxicity.
