Naproxen / Esomeprazole Rowex Ltd (Esomeprazole, Naproxen)

Naproxen / Esomeprazole acts on inflammatory and gastric pathways to manage pain and protect the gastrointestinal tract.

• Pain relief: reduces musculoskeletal pain associated with acute and chronic conditions.
• Osteoarthritis: alleviates joint pain and improves functional mobility.
• Rheumatoid arthritis: diminishes inflammatory joint symptoms and swelling.
• Prevention of NSAID‑induced gastric ulcers: provides gastro‑protective effect while NSAID therapy is required.

• Naproxen reversibly inhibits cyclo‑oxygenase‑1 and cyclo‑oxygenase‑2 enzymes, decreasing prostaglandin synthesis and thereby reducing inflammation and pain. Esomeprazole irreversibly binds to the gastric H+/K+‑ATPase pump on parietal cells, suppressing gastric acid secretion and promoting ulcer healing and protection.

The combination may cause a range of adverse reactions, from mild to severe.

Common Side Effects

• Dyspepsia: discomfort or burning in the upper abdomen.
• Nausea: feeling of sickness often accompanied by an urge to vomit.
• Headache: mild to moderate pain in the head region.
• Dizziness: sensation of light‑headedness or unsteadiness.
• Abdominal pain: cramping or tenderness in the stomach area.
• Diarrhoea: loose, frequent stools.

Serious or Rare Side Effects

• Gastrointestinal bleeding: potentially life‑threatening hemorrhage.
• Ulcer perforation: a hole in the stomach or intestinal lining.
• Severe liver injury: jaundice, elevated enzymes, hepatic failure.
• Stevens‑Johnson syndrome: serious skin and mucous membrane reaction.
• Anaphylaxis: rapid, severe allergic response.
• Acute renal failure: sudden loss of kidney function.

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

• Assess GI risk: review history of ulcers or gastrointestinal bleeding.
• Monitor renal function: especially in patients with existing kidney disease.
• Avoid in severe hepatic disease: liver impairment may alter drug metabolism.
• Use with caution in elderly: increased susceptibility to side effects.
• Avoid concomitant anticoagulants: heightened risk of bleeding.
• Store at ambient temperature: keep in the original pack, protect from moisture.

Naproxen / Esomeprazole can interact with several drug classes, requiring careful management.

Major Interactions (Avoid)

• Anticoagulants (e.g., warfarin): increased risk of serious bleeding.
• Other NSAIDs or COX‑2 inhibitors: additive gastrointestinal toxicity.
• Corticosteroids: heightened ulcer risk when combined.
• Selective serotonin reuptake inhibitors (SSRIs): may amplify bleeding tendency.
• Methotrexate: reduced clearance leading to toxicity.

Moderate Interactions (Monitor Closely)

• Diuretics: may diminish renal perfusion and function.
• ACE inhibitors or ARBs: possible decline in renal function.
• Lithium: increased serum lithium concentrations.
• Digoxin: altered absorption affecting drug levels.
• Antacids containing aluminium or magnesium: may affect esomeprazole absorption.
