Ibuprofene Eg (Ibuprofen)

Ibuprofen, an NSAID, works by inhibiting prostaglandin synthesis to relieve common inflammatory conditions.

• Pain: Provides analgesic relief for mild to moderate acute pain such as headache, dental procedures, menstrual cramps, or musculoskeletal discomfort.
• Fever: Lowers elevated body temperature caused by viral or bacterial infections, helping to improve comfort and reduce metabolic demand.
• Inflammation: Decreases swelling, redness, and stiffness in inflammatory conditions including osteoarthritis, rheumatoid arthritis, and soft‑tissue injuries.
• Post‑operative pain: Assists in controlling postoperative discomfort, facilitating early mobilization and recovery after minor surgical interventions.

• Ibuprofen exerts its effect by non‑selectively inhibiting the cyclooxygenase enzymes COX‑1 and COX‑2. This blockade reduces the conversion of arachidonic acid to prostaglandins and thromboxanes, key mediators of inflammation, pain, and fever. By lowering prostaglandin levels at sites of tissue injury, ibuprofen diminishes peripheral sensitization of nociceptors and the febrile response, producing analgesic, antipyretic, and anti‑inflammatory actions. The reversible inhibition allows normal prostaglandin production to resume after the drug is cleared.

Ibuprofen may cause a range of adverse reactions, varying from mild to severe, depending on individual susceptibility and dosage.

Common Side Effects

• Gastrointestinal discomfort: nausea, dyspepsia, or abdominal pain.
• Headache or dizziness.
• Mild skin rash or itching.
• Elevated blood pressure in some patients.

Serious or Rare Side Effects

• Gastrointestinal ulceration or bleeding, which can be life‑threatening.
• Renal impairment or acute kidney injury, especially with dehydration.
• Severe allergic reactions such as anaphylaxis or angioedema.
• Hepatotoxicity manifested by jaundice or abnormal liver enzymes.

When prescribing ibuprofen, clinicians should consider several precautionary measures to minimize risk.

• Assess renal function: evaluate baseline kidney status before initiating therapy.
• Review gastrointestinal history: avoid use in patients with active ulcers or bleeding disorders.
• Monitor cardiovascular risk: use cautiously in individuals with hypertension or heart disease.
• Limit duration: prescribe the lowest effective dose for the shortest necessary period.
• Avoid use in late pregnancy: contraindicated during the third trimester due to fetal risks.
• Store at ambient temperature: keep below 25 °C in the original container, protected from moisture.

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

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased bleeding risk.
• High‑dose aspirin: heightened 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 reduced diuretic efficacy and kidney injury.
• Lithium: ibuprofen can raise lithium serum levels, risking toxicity.
