Ibuprofene Pensa (Ibuprofen)

Ibuprofen acts as a non‑steroidal anti‑inflammatory drug that reduces prostaglandin‑mediated inflammation and pain.

• Mild to moderate pain: provides analgesic relief for headaches, dental discomfort, and musculoskeletal aches.
• Fever: lowers elevated body temperature in acute febrile states.
• Arthritis (osteoarthritis and rheumatoid arthritis): diminishes joint inflammation and improves mobility.
• Menstrual cramps: alleviates dysmenorrhea associated with uterine muscle contractions.

• Ibuprofen non‑selectively inhibits cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, decreasing conversion of arachidonic acid to prostaglandins and thromboxanes. The reduced prostaglandin synthesis diminishes inflammation, pain signaling, and fever generation in peripheral tissues and the hypothalamus, while partially preserving gastric protective prostaglandins, which accounts for its therapeutic profile.

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 intensity.
• Dizziness: transient sensation of light‑headedness.
• Rash: mild skin erythema or itching.

Serious or Rare Side Effects

• Peptic ulcer bleeding: gastrointestinal hemorrhage requiring medical attention.
• Renal impairment: acute kidney injury especially in volume‑depleted patients.
• Severe hypersensitivity: anaphylaxis or Stevens‑Johnson syndrome.
• Cardiovascular events: increased risk of myocardial infarction or stroke with high‑dose or prolonged use.

When prescribing ibuprofen, clinicians should evaluate patient‑specific risk factors and follow safety guidelines.

• Assess gastrointestinal risk: consider protective agents in patients with history of ulcers or bleeding.
• Monitor renal function: avoid or adjust dose in severe renal impairment.
• Avoid in known hypersensitivity: discontinue if rash or angioedema develops.
• Use caution with anticoagulants: increased bleeding tendency.
• Limit use in pregnancy: avoid in third trimester unless essential.
• Store at ambient temperature: keep in original packaging, protect from moisture.

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

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): heightened bleeding risk.
• Selective COX‑2 inhibitors (e.g., celecoxib): additive gastrointestinal toxicity.
• Lithium: increased serum lithium concentrations.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: potential reduction in renal function.
• Diuretics: may exacerbate renal impairment.
• Methotrexate: reduced clearance leading to toxicity.
• SSRIs or SNRIs: increased risk of upper gastrointestinal bleeding.
