Ibuprofene Zentiva France (Ibuprofen Lysine)

Ibuprofen lysine is an NSAID that acts on prostaglandin pathways to manage pain and inflammation.

• Mild to moderate pain: provides analgesia for headaches, dental pain, musculoskeletal aches, and postoperative discomfort.
• Fever: lowers elevated body temperature associated with infections or inflammatory states.
• Arthritis: reduces joint swelling and pain in osteoarthritis and rheumatoid arthritis.

• Ibuprofen lysine exerts its effect by non‑selectively inhibiting cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, which blocks the conversion of arachidonic acid to prostaglandins. The resulting decrease in prostaglandin synthesis diminishes inflammation, pain signaling, and fever generation at the site of tissue injury or infection.

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

Common Side Effects

• Gastrointestinal discomfort: nausea, dyspepsia, or abdominal pain.
• Headache: mild to moderate intensity.
• Dizziness or vertigo.
• Skin rash or mild itching.
• Elevated blood pressure in susceptible individuals.

Serious or Rare Side Effects

• Gastrointestinal ulceration or bleeding.
• Renal impairment or acute kidney injury.
• Severe hypersensitivity reactions, including anaphylaxis.
• Hepatotoxicity with elevated liver enzymes.
• Cardiovascular events such as myocardial infarction or stroke in high‑risk patients.

Before using ibuprofen lysine, consider the following safety measures.

• Cardiovascular risk: avoid in patients with uncontrolled hypertension or recent heart events.
• Gastrointestinal history: use cautiously if there is a past ulcer or bleeding disorder.
• Renal function: monitor kidney function in those with chronic kidney disease.
• Pregnancy and lactation: consult a healthcare professional before use during pregnancy or breastfeeding.
• Concomitant medications: review all current drugs for potential interactions.
• Store at ambient temperature: keep below 25°C in the original packaging, protected from moisture and direct sunlight.

Ibuprofen lysine can affect the activity of several other medicines.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of serious bleeding.
• High‑dose aspirin: additive gastrointestinal toxicity.
• Selective COX‑2 inhibitors: heightened cardiovascular risk.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: possible reduction in antihypertensive effect.
• Diuretics: may impair renal function when combined.
• Lithium: ibuprofen can raise lithium serum levels, requiring monitoring.
