Ibuprofeno Farmalider (Ibuprofen)

Ibuprofen acts as an analgesic, antipyretic and anti‑inflammatory agent, providing symptom relief across several common conditions.

• Pain: Reduces mild to moderate nociceptive pain such as headaches, dental pain, or musculoskeletal discomfort.
• Fever: Lowers elevated body temperature associated with infections or inflammatory processes.
• Inflammation: Decreases swelling and stiffness in conditions like osteoarthritis or minor soft‑tissue injuries.
• Menstrual cramps: Alleviates dysmenorrhea associated with uterine contractions.

• Ibuprofen exerts its effect by non‑selectively inhibiting cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, which catalyze the conversion of arachidonic acid to prostaglandins. By reducing prostaglandin synthesis, it diminishes peripheral sensitisation of nociceptors, lowers the hypothalamic set‑point for temperature, and limits inflammatory exudate formation, resulting in analgesic, antipyretic and anti‑inflammatory actions.

Ibuprofen may cause a range of adverse reactions, from mild and transient to serious and potentially life‑threatening.

Common Side Effects

• Nausea: mild stomach upset or queasiness.
• Dyspepsia: indigestion or heartburn.
• Headache: transient cranial discomfort.
• Dizziness: light‑headed sensation.
• Rash: mild skin redness or itching.
• Diarrhoea: loose stools.

Serious or Rare Side Effects

• Gastrointestinal bleeding or ulceration: black stools or vomiting blood.
• Renal impairment: reduced urine output or swelling.
• Severe allergic reactions: hives, swelling of face or throat, anaphylaxis.
• Hepatotoxicity: jaundice or elevated liver enzymes.
• Stevens‑Johnson syndrome or toxic epidermal necrolysis: widespread skin blistering.
• Cardiovascular events: increased risk of heart attack or stroke.

When using ibuprofen, clinicians should evaluate patient risk factors and follow safety measures to minimise adverse outcomes.

• Assess gastrointestinal risk: evaluate history of ulcers, bleeding, or concomitant NSAID use.
• Monitor renal function: check creatinine and electrolytes in patients with kidney disease or dehydration.
• Use lowest effective dose: limit duration to the shortest period needed for symptom control.
• Avoid in known hypersensitivity: discontinue if allergic reactions occur.
• Caution in cardiovascular disease: consider alternative therapy for patients with heart failure or ischemic disease.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Ibuprofen can interact with several medicines, altering efficacy or increasing toxicity; interactions are classified by clinical significance.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): heightened risk of serious bleeding.
• Other NSAIDs or aspirin: additive gastrointestinal toxicity.
• Corticosteroids: increased ulceration risk.
• Lithium: elevated lithium serum levels.
• Methotrexate: reduced clearance leading to toxicity.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: possible reduction in antihypertensive effect and renal function.
• Diuretics: enhanced risk of renal impairment.
• Selective serotonin reuptake inhibitors (SSRIs): modest increase in bleeding tendency.
• Beta‑blockers: potential attenuation of blood pressure control.
• Antidiabetic agents: may affect glycaemic control.
