26159-34-2 Usage

Brand name

Aleve (Bayer); Anaprox (Roche);Naprelan (Stat Trade).

Non-steroidal anti-inflammatory analgesic

Naproxen sodium is a non-steroidal anti-inflammatory analgesic drug which is more tolerable to human, belonging to the phenylpropionic acid compounds. It plays anti-inflammatory effect by inhibiting prostaglandin synthesis.It is absorbed rapidly after oral administration and the plasma reached the peak concentration within 2 to 4 hours. Food has little effect on the rate of absorption. Naproxen and plasma protein are highly binded(99%); the plasma concentration is between 23~40mcg/ml. The metabolic process is demethylation and then combining with glucuronide; the elimination half-life is 12 to 15 hours, mainly excreted by the urine. Clinical application is to relieve a variety of mild to moderate degree of pain, such as tooth extraction and other postoperative pain, primary dysmenorrhea and headache. It is also used for rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, juvenile arthritis, tendinitis, bursitis and acute gouty arthritis; it also plays a role in arthritis pain, swelling and activity restricted symptom. Psoriatic arthritis and Reiter's syndrome can also be treated with this product. Compared with ibuprofen, fenoprofen, aspirin, sulindac and indomethacin, the symptom relief effect was similar, but the incidence and severity of adverse reactions in the gastrointestinal and neurological systems were low. In addition, this product is also the same as aspirin which can inhibit platelet aggregation and prolong bleeding time; but the effect is reversible, and can be restored after stopping.
Naproxen sodium and plasma protein binding rate is high (99%), and other protein-binding drugs can be replaced by its joint out. Therefore, the acceptance of these drugs (such as oral anticoagulants, sulfonylurea, hydantoins) people should observe the interaction effects. At the same time the application of probenecid, naproxen can increase the plasma concentration, half-life period. Magnesium hydroxide, aluminum can make this product absorption rate slightly lower; sodium bicarbonate can make it higher.
