Naproxen/Esomeprazole Rowex (Esomeprazole, Naproxen)

Naproxen/Esomeprazole is indicated for conditions where pain, inflammation, and gastric protection are required.

• Osteoarthritis: reduces joint pain and swelling while lowering risk of NSAID‑related gastric ulcers.
• Rheumatoid arthritis: alleviates inflammatory symptoms and provides gastro‑protective effect during chronic NSAID therapy.
• Acute musculoskeletal pain: offers rapid analgesia and anti‑inflammatory action with concurrent ulcer prevention.
• Gastro‑oesophageal reflux disease (GERD) requiring NSAID therapy: controls acid secretion and protects the gastric mucosa.

• Naproxen non‑selectively inhibits cyclo‑oxygenase‑1 and cyclo‑oxygenase‑2 enzymes, decreasing prostaglandin synthesis and thereby reducing pain, fever, and inflammation. Esomeprazole binds irreversibly to the gastric H⁺/K⁺‑ATPase pump on parietal cells, suppressing gastric acid secretion. The fixed‑dose combination therefore couples anti‑inflammatory activity with sustained acid suppression, minimizing NSAID‑induced gastric mucosal injury.

Naproxen/Esomeprazole may cause a range of adverse reactions, varying from mild to severe.

Common Side Effects

• Dyspepsia: upper abdominal discomfort or fullness.
• Headache: mild to moderate intensity.
• Nausea: feeling of sickness, sometimes with vomiting.
• Diarrhea: loose stools.
• Constipation: reduced bowel movements.
• Abdominal pain: cramping or tenderness.

Serious or Rare Side Effects

• Gastrointestinal bleeding or ulcer perforation.
• Severe allergic reactions such as anaphylaxis or Stevens‑Johnson syndrome.
• Liver enzyme elevation indicating possible hepatic injury.
• Acute renal failure or significant decline in kidney function.
• Thrombotic events such as myocardial infarction or stroke (especially with high NSAID exposure).
• Severe electrolyte disturbances (e.g., hypomagnesemia).

Before prescribing Naproxen/Esomeprazole, clinicians should consider several precautionary measures to ensure patient safety.

• Assess gastrointestinal risk: evaluate history of ulcers, bleeding, or chronic NSAID use.
• Monitor renal function: check serum creatinine and electrolytes, especially in elderly or dehydrated patients.
• Evaluate cardiovascular status: avoid in patients with recent myocardial infarction or uncontrolled hypertension.
• Use 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 packaging, protect from moisture and direct sunlight.

Naproxen/Esomeprazole can interact with other medicines, altering efficacy or safety.

Major Interactions (Avoid)

• Other NSAIDs (e.g., ibuprofen, diclofenac): increase risk of gastrointestinal bleeding.
• Anticoagulants (e.g., warfarin, direct oral anticoagulants): potentiate bleeding tendency.
• Selective serotonin reuptake inhibitors (e.g., fluoxetine, sertraline): elevate bleeding risk.
• Corticosteroids (e.g., prednisone): synergistic ulcerogenic effect.
• CYP2C19 inhibitors (e.g., omeprazole, fluconazole): may raise esomeprazole plasma levels.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or ARBs (e.g., lisinopril, losartan): may reduce renal perfusion when combined with NSAIDs.
• Diuretics (e.g., furosemide): risk of reduced diuretic efficacy and renal impairment.
• Lithium: NSAIDs can increase lithium concentrations.
• Methotrexate: NSAIDs may decrease clearance, raising toxicity risk.
• Antihypertensives (e.g., beta‑blockers): monitor blood pressure as NSAIDs may blunt antihypertensive effect.
