Ibuprofeno Zentiva Ks (Ibuprofen)

Ibuprofen acts systemically to alleviate symptoms associated with pain, fever, and inflammation.

• Mild to moderate pain: provides analgesia for headaches, dental pain, musculoskeletal aches, and postoperative discomfort.
• Fever: reduces elevated body temperature in acute febrile illnesses.
• Inflammatory conditions such as arthritis: diminishes joint swelling and stiffness in osteoarthritis and rheumatoid arthritis.

• Ibuprofen non‑selectively inhibits cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, decreasing the conversion of arachidonic acid to prostaglandins. Lower prostaglandin levels reduce inflammation, pain signaling, and the hypothalamic set‑point for temperature, producing analgesic, antipyretic, and anti‑inflammatory effects.

Adverse reactions may vary in frequency and severity.

Common Side Effects

• Gastrointestinal upset: nausea, dyspepsia, or abdominal discomfort.
• Headache: mild to moderate intensity.
• Dizziness or vertigo.
• Skin rash or mild itching.

Serious or Rare Side Effects

• Gastrointestinal bleeding or ulcer perforation.
• Acute renal impairment, especially in volume‑depleted patients.
• Severe allergic reactions such as anaphylaxis or angioedema.
• Hepatic enzyme elevation or liver injury.
• Hematologic abnormalities including thrombocytopenia.
• Cardiovascular events such as myocardial infarction or stroke in high‑risk individuals.

Before using ibuprofen, consider the following safety measures.

• Assess gastrointestinal risk: avoid in patients with active ulcers or a history of GI bleeding.
• Monitor renal function: use caution in those with chronic kidney disease or dehydration.
• Use the lowest effective dose: limit duration to the shortest period needed for symptom control.
• Avoid in known hypersensitivity: discontinue if allergic reactions occur.
• Store at room temperature: keep in the original pack, protect from moisture and direct sunlight.

Ibuprofen can interact with several medicines, requiring attention to dosage and monitoring.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of bleeding.
• Selective serotonin reuptake inhibitors (SSRIs): heightened gastrointestinal bleeding risk.
• Lithium: ibuprofen may raise serum lithium concentrations.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: may reduce renal perfusion, especially in volume‑depleted patients.
• Diuretics: combined use can impair kidney function.
• Methotrexate: ibuprofen can increase methotrexate toxicity at high doses.
