Ibuprofen Alkaloid-Int (Ibuprofen)

Ibuprofen acts systemically to reduce prostaglandin‑mediated inflammation and pain, making it useful across several common conditions.

• Pain: provides analgesic relief for mild to moderate acute or chronic pain.
• Fever: lowers elevated body temperature associated with infectious or inflammatory states.
• Inflammation: diminishes swelling and tenderness in inflamed tissues.
• Osteoarthritis: improves joint function and reduces discomfort in degenerative joint disease.
• Rheumatoid arthritis: helps control pain and swelling in autoimmune joint inflammation.

• Ibuprofen non‑selectively inhibits cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, decreasing the conversion of arachidonic acid to prostaglandins. Reduced prostaglandin synthesis leads to lowered inflammation, pain signaling, and fever generation at peripheral and central sites.

Adverse reactions may range from mild to serious, depending on individual susceptibility and duration of therapy.

Common Side Effects

• Nausea: mild stomach upset that often resolves with food.
• Dyspepsia: discomfort or burning in the upper abdomen.
• Headache: transient tension‑type headache.
• Dizziness: occasional light‑headed sensation.
• Rash: mild skin redness or itching.
• Diarrhoea: loose stools without blood.

Serious or Rare Side Effects

• Gastrointestinal bleeding: visible blood in stool or vomit.
• Peptic ulcer perforation: sudden severe abdominal pain.
• Renal impairment: reduced urine output or swelling.
• Severe allergic reaction: swelling of face, lips, or throat.
• Hepatic enzyme elevation: abnormal liver function tests.
• Cardiovascular events: increased risk of heart attack or stroke in high‑risk patients.

Before initiating therapy, consider patient‑specific risk factors and monitor for adverse events.

• Assess gastrointestinal risk: evaluate history of ulcers or bleeding.
• Monitor renal function: check serum creatinine in patients with kidney disease.
• Use lowest effective dose: limit duration to the shortest period needed.
• Avoid in known hypersensitivity: discontinue if allergic signs appear.
• Take with food or milk: helps reduce stomach irritation.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Ibuprofen can alter the pharmacokinetics or pharmacodynamics of several medicines; careful review is essential.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased bleeding risk.
• Other NSAIDs or aspirin: additive gastrointestinal toxicity.
• Corticosteroids: heightened ulcer risk.
• ACE inhibitors or ARBs: possible reduction in renal function.
• Lithium: elevated lithium serum levels.

Moderate Interactions (Monitor Closely)

• Diuretics: may reduce antihypertensive effect.
• Methotrexate: decreased clearance, risk of toxicity.
• SSRIs: modest increase in bleeding tendency.
• Oral hypoglycemics: potential alteration of blood glucose control.
• Antihypertensives: possible attenuation of blood pressure‑lowering effect.
