Naldorex (Naproxen Sodium)

Naproxen sodium, the active ingredient in Naldorex, is a nonsteroidal anti-inflammatory drug (NSAID) presented as an oral formulation for systemic use. It is employed to relieve mild to moderate pain, reduce inflammation in musculoskeletal disorders, and lower fever in adult patients.

GNH USA supplies Naldorex as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Naproxen sodium works by inhibiting prostaglandin synthesis, making it useful for several painful and inflammatory conditions.

- Mild to moderate pain: provides analgesic relief for headaches, dental pain, and musculoskeletal aches. - Osteoarthritis: reduces joint inflammation and improves mobility. - Rheumatoid arthritis: helps control chronic inflammation and joint damage. - Fever: lowers elevated body temperature associated with acute infections.

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

Common Side Effects: - Gastrointestinal upset: nausea, dyspepsia, or abdominal discomfort. - Headache: mild to moderate intensity. - Dizziness: transient light‑headedness. - Rash: mild skin irritation or erythema.

Serious or Rare Side Effects: - Gastrointestinal bleeding or ulceration. - Cardiovascular events such as myocardial infarction or stroke. - Acute renal impairment or failure. - Severe skin reactions including Stevens‑Johnson syndrome. - Anaphylactic or anaphylactoid reactions.

Before initiating therapy, clinicians should consider several safety measures.

- Assess gastrointestinal risk: evaluate history of ulcers or bleeding. - Monitor renal function: check serum creatinine and urine output regularly. - Evaluate cardiovascular history: use caution in patients with heart disease. - Use the lowest effective dose: limit duration to the shortest necessary period. - Avoid in known hypersensitivity: discontinue if allergic reactions occur. - Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

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

Major Interactions (Avoid): - Anticoagulants (e.g., warfarin): increased risk of bleeding. - Other NSAIDs or aspirin: additive gastrointestinal toxicity. - Selective serotonin reuptake inhibitors (SSRIs): heightened bleeding tendency.

Moderate Interactions (Monitor Closely): - ACE inhibitors (e.g., lisinopril): may reduce antihypertensive effect. - Diuretics (e.g., furosemide): potential for reduced renal perfusion.
