naproxen bnf

17.0093.00

Naproxen is a so-called NSAID: an anti-inflammatory pain reliever and the active ingredient of this medicine. It helps to slow down the production of prostaglandins, a hormone-like substance that acts as a mediator of pain, fever, and inflammatory responses such as swelling and redness of the skin. Naproxen can be used to treat conditions involving pain and inflammation. Due to its anti-inflammatory effect, Naprosyn (naproxen) is often prescribed for rheumatic disorders and joint problems such as rheumatoid arthritis, osteoarthritis, Bechterew’s disease, carpal tunnel syndrome, tennis elbow, and bursitis. It is also commonly used to treat severe pain from menstrual cramps, headaches, (dental) surgery, and other sources.

What is Naproxen?

Naproxen bnf belongs to the group of medicines called non-steroidal anti-inflammatory drugs, with anti-inflammatory (against inflammation), analgesic (against pain), and antipyretic/antipyretic (fever reduction) properties.

Naproxen is indicated for the treatment of inflammatory and painful processes of the joints, muscles, tendons, and ligaments such as rheumatoid arthritis, osteoarthritis, and ankylosing spondylitis. Naproxen is also indicated for the treatment of acute attacks of gout, rheumatoid syndromes, and for menstrual pain.  .  .  .  .   .  .  . . . . . . . . . . . . . . . . . . . . . . .  . . . . . . . ............. ........................

How does naproxen bnf work?

The Naproxen sodium tablet is a non-steroidal anti-inflammatory drug (NSAID), with analgesic, anti-inflammatory, and antipyretic action. Naproxen sodium is a derivative of propionic acid chemically related to the group of aryl acetic acids. Naproxen sodium is a white to yellowish-white crystalline solid readily soluble in neutral pH water.

Its anti-inflammatory effect has been verified even in adrenalectomized animals, which indicates that its action is not mediated through the pituitary-adrenal axis. Like other non-steroidal anti-inflammatory agents, naproxen inhibits prostaglandin synthetase, although the exact mechanism of anti-inflammatory action is unknown for these types of products.

In patients with severe night pain and/or morning numbness, patients who go from another antirheumatic treatment to Naproxen and in osteoarthritis with pain as the predominant symptom, it is recommended to start therapy with doses of one and a half tablets to two tablets (750- 1000 mg) daily for several weeks.

Acute musculoskeletal processes: The recommended starting dose is one tablet (500 mg) followed by half a tablet (250 mg) every 6 to 8 hours.

In acute crises and as long as there is no history of gastrointestinal disease, the dose can be increased to three tablets (1500 mg), for no more than 2 weeks.

Pediatric patients: In juvenile rheumatoid arthritis, a dose of 10 mg/kg/day is recommended, divided into two doses, at 12-hour intervals.

Special dosage: In the elderly or in patients with heart, liver, or kidney disorders, the dose should be reduced.
