Naproxene Sodique Arrow (Naproxen Sodium)

Naproxen sodium acts on inflammatory pathways to provide analgesic and antipyretic benefits across several conditions.

• Pain: alleviates mild to moderate acute pain such as dental or postoperative discomfort.
• Inflammation: reduces swelling associated with soft‑tissue injuries and inflammatory disorders.
• Fever: lowers elevated body temperature in febrile states.
• Arthritis: eases joint pain and stiffness in osteoarthritis and rheumatoid arthritis.
• Musculoskeletal pain: improves mobility and comfort in back, neck and muscle strains.

• Naproxen sodium 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.

Naproxen sodium 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.
• Mild skin rash or itching.

Serious or Rare Side Effects

• Gastrointestinal ulceration or bleeding.
• Renal impairment or reduced kidney function.
• Elevated liver enzymes indicating hepatic stress.
• Severe hypersensitivity reactions such as angioedema or anaphylaxis.

Before using Naproxene Sodique Arrow, consider the following safety measures.

• Cardiovascular risk: avoid in patients with uncontrolled hypertension or recent myocardial infarction.
• Gastrointestinal history: use cautiously in individuals with prior ulcers or bleeding disorders.
• Renal function: monitor kidney parameters in patients with chronic kidney disease.
• Pregnancy: limit use to the second trimester; avoid in the third trimester.
• Concomitant NSAIDs: do not combine with other non‑steroidal anti‑inflammatory drugs.
• Store at ambient temperature: keep below 25°C in the original packaging, protected from moisture and direct sunlight.

Naproxen sodium can interact with several medicines, altering efficacy or safety.

Major Interactions (Avoid)

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

Moderate Interactions (Monitor Closely)

• ACE inhibitors or diuretics: may reduce renal perfusion, monitor kidney function.
• Lithium: NSAIDs can raise lithium levels, requiring serum monitoring.
• Methotrexate: reduced clearance may increase toxicity, especially at high doses.
