Ibuprofene Zentiva Italia (Ibuprofen)

Ibuprofen acts as an analgesic and antipyretic by inhibiting prostaglandin synthesis, making it useful for several common conditions.

• Mild to moderate pain: provides relief from headaches, dental pain, musculoskeletal discomfort, and postoperative pain.
• Fever: reduces elevated body temperature associated with infections or inflammatory processes.
• Arthritis and other inflammatory disorders: decreases joint swelling and improves mobility in osteoarthritis and rheumatoid arthritis.

• Ibuprofen exerts its effect through non‑selective inhibition of cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes. By blocking these enzymes, the conversion of arachidonic acid to prostaglandins is reduced, leading to decreased inflammation, pain signaling, and fever generation. The inhibition of COX‑1 also affects protective gastric prostaglandins, which contributes to its gastrointestinal safety profile.

Ibuprofen may cause a range of adverse reactions, varying from mild to serious.

Common Side Effects

• Nausea: mild stomach upset or queasiness.
• Dyspepsia: indigestion or heartburn.
• Headache: transient head pain.
• Dizziness: feeling light‑headed or unsteady.
• Rash: mild skin redness or itching.
• Diarrhoea: loose stools.

Serious or Rare Side Effects

• Gastrointestinal bleeding or ulceration: severe stomach or intestinal bleeding.
• Renal impairment: reduced kidney function or acute kidney injury.
• Severe allergic reaction: anaphylaxis, swelling of face or throat.
• Hepatotoxicity: elevated liver enzymes or liver injury.
• Thrombocytopenia: low platelet count leading to easy bruising.
• Cardiovascular events: increased risk of heart attack or stroke.

When prescribing or dispensing ibuprofen, several safety considerations should be observed.

• Assess gastrointestinal risk: evaluate history of ulcers, bleeding, or chronic NSAID use.
• Evaluate renal function: monitor creatinine in patients with kidney disease or dehydration.
• Monitor cardiovascular status: use lowest effective dose in patients with heart disease or hypertension.
• Use lowest effective dose for shortest duration: limit exposure to reduce adverse event risk.
• Avoid in known hypersensitivity: contraindicated for patients allergic to ibuprofen or other NSAIDs.
• Store at ambient temperature: keep in original packaging, protect from moisture and direct sunlight.

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

Major Interactions (Avoid)

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