Ibuprofene Fg (Ibuprofen)

• Ibuprofen acts systemically to inhibit cyclo‑oxygenase enzymes, providing relief across several painful and inflammatory conditions.
• Pain: Provides analgesic effect by reducing prostaglandin‑mediated nociception.
• Fever: Lowers elevated body temperature through central inhibition of prostaglandin synthesis.
• Inflammation: Decreases swelling and redness by limiting inflammatory mediator production.
• Arthritis: Alleviates joint pain and stiffness associated with osteoarthritis and rheumatoid arthritis.

• Ibuprofen reversibly inhibits both cyclo‑oxygenase‑1 (COX‑1) and cyclo‑oxygenase‑2 (COX‑2) enzymes, which catalyze the conversion of arachidonic acid to prostaglandins and thromboxanes. By reducing prostaglandin synthesis, it diminishes peripheral sensitization of nociceptors, lowers the hypothalamic set‑point for temperature, and curtails inflammatory vascular responses. The inhibition is dose‑dependent and temporary, allowing normal prostaglandin production to resume after the drug is cleared.

Ibuprofen may cause a range of adverse reactions, from mild and frequent to rare but serious.

Common Side Effects

• Gastrointestinal discomfort: nausea, dyspepsia, or mild abdominal pain.
• Headache: transient headache episodes.
• Dizziness: occasional light‑headedness.
• Rash: mild skin erythema or itching.

Serious or Rare Side Effects

• Gastrointestinal ulceration or bleeding: severe stomach or intestinal bleeding.
• Renal impairment: reduced kidney function or acute renal failure.
• Hepatotoxicity: elevated liver enzymes or hepatitis.
• Cardiovascular events: increased risk of heart attack or stroke, especially with high‑dose or prolonged use.

• When considering ibuprofen therapy, several safety measures should be observed to minimize risk.
• Assess renal function: evaluate baseline kidney status before initiating therapy.
• Monitor gastrointestinal risk: avoid use in patients with active ulcers or history of bleeding.
• Limit use in cardiovascular disease: weigh benefits against increased thrombotic risk.
• Avoid in late pregnancy: contraindicated during the third trimester.
• Review concomitant medications: check for interactions with anticoagulants, antihypertensives, or other NSAIDs.
• Store at ambient temperature: keep in original container, protect from moisture and direct sunlight.

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

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased bleeding risk.
• High‑dose aspirin: heightened gastrointestinal toxicity.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: may reduce antihypertensive effect and impair renal function.
• Diuretics: potential for decreased diuretic efficacy and renal compromise.
• Lithium: ibuprofen can raise lithium serum levels, risking toxicity.
