Naproxen 123 Acurae Pharma (Naproxen Sodium)

Naproxen sodium is an NSAID that acts on inflammatory pathways to manage several painful and inflammatory disorders.

• Pain relief: reduces moderate to severe pain associated with musculoskeletal injuries and postoperative states.
• Rheumatoid arthritis: diminishes joint swelling, stiffness, and pain in chronic inflammatory arthritis.
• Osteoarthritis: alleviates pain and improves joint function in degenerative joint disease.
• Dysmenorrhea: eases menstrual cramps and associated pelvic discomfort.
• Gout flares: controls acute gouty arthritis pain and inflammation.

• Naproxen sodium reversibly inhibits cyclooxygenase‑1 (COX‑1) and cyclooxygenase‑2 (COX‑2) enzymes, decreasing the conversion of arachidonic acid to prostaglandins. The reduced prostaglandin synthesis leads to diminished inflammation, analgesia, and antipyretic effects without directly affecting leukotriene pathways.

Adverse reactions may range from mild to severe and should be monitored during therapy.

Common Side Effects

• Gastrointestinal upset: dyspepsia, abdominal pain, or nausea.
• Headache: mild to moderate intensity.
• Dizziness or vertigo.
• Rash or mild skin irritation.
• Elevated liver enzymes.

Serious or Rare Side Effects

• Gastrointestinal bleeding or ulcer perforation.
• Cardiovascular events such as myocardial infarction or stroke.
• Acute renal failure or worsening of chronic kidney disease.
• Severe skin reactions including Stevens‑Johnson syndrome.
• Hepatotoxicity with jaundice.
• Anaphylaxis or severe hypersensitivity reactions.

Before initiating therapy, clinicians should evaluate patient‑specific risk factors and monitor for adverse events.

• Assess gastrointestinal risk: review history of ulcers, bleeding, or chronic NSAID use.
• Evaluate cardiovascular profile: consider existing heart disease or risk factors.
• Monitor renal function: check baseline creatinine in patients with kidney impairment.
• Use caution in hepatic disease: periodic liver function tests are advisable.
• Avoid use in patients with known hypersensitivity to naproxen or other NSAIDs.
• Store at ambient temperature: keep below 25°C, protect from moisture and light, retain in the original container.

Naproxen sodium can alter the pharmacodynamics or pharmacokinetics of several co‑administered medicines.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of serious bleeding.
• Other NSAIDs or aspirin: additive gastrointestinal toxicity.
• Corticosteroids: heightened ulcer risk.
• Selective serotonin reuptake inhibitors (SSRIs): amplified bleeding tendency.
• Lithium: elevated lithium serum concentrations.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs: possible reduction in antihypertensive effect and renal function.
• Diuretics: risk of reduced renal perfusion.
• Methotrexate: decreased clearance leading to toxicity.
• Oral hypoglycemics: potential alteration of blood glucose control.
• Antihypertensive agents: may blunt blood pressure‑lowering response.
