It works by inhibiting both the COX-1 and COX-2 enzymes. Naproxen and naproxen sodium are marketed under various trade names including: Aleve, Anaprox, Antalgin, Miranax, Naprelan, Naprogesic, Naprosyn, Proxen, Synflex, Xenobid.Naproxen was originally marketed as the prescription drug Naprosyn in 1976, and naproxen sodium was first marketed under the trade name Anaprox in 1980. It remains a prescription-only drug in much of the world. The U.S. Food and Drug Administration (FDA) approved the use of naproxen sodium as an over-the-counter (OTC) drug in 1994, where OTC preparations are sold under the trade name Aleve. In Australia, small packets of lower-strength preparations of naproxen sodium are Schedule 2 Pharmacy Medicines. In the UK, 250mg tablets of naproxen were approved for OTC sale under the brand name Feminax Ultra in 2008, for the treatment of primary dysmenorrhoea in women aged 15 to 50.// Structure and detailsNaproxen is a member of the 2-arylpropionic acid (profen) family of NSAIDs. It is an odorless, white to off-white crystalline substance. It is lipid-soluble and practically insoluble in water. It has a melting point of 153 °C. Adverse effects and warningsIP110 Naproxen Tablets: Like other NSAIDs, naproxen can inhibit the excretion of sodium and lithium. Extreme care must be taken by those who use this drug along with lithium supplements. Naproxen is also not recommended for use with NSAIDs of the salicylate family (Aspirin) (drugs may reduce each other's effects) or with anticoagulants (may increase risk of bleeding). Naproxen preparations containing sodium (e.g., Anaprox, Aleve, etc.) are not recommended for use in patients with sodium-sensitive hypertension, due to potential adverse effects on blood pressure in this small subset of hypertensive patients.In August 2006, the Journal Birth Defects Research Part B published results indicating that pregnant women who take NSAIDs including naproxen in the first trimester run an increased risk of having a child with congenital birth defects, particularly heart anomalies. IP110-Naproxen link to PseudoporphyriaNaproxen IP110 has also been linked to cases of Pseudoporphyria, specifically in those with skin type II or lower, especially with blue or green eyes. Risk of heart attack or strokeThe National Institutes of Health prematurely terminated a randomized clinical trial of naproxen and celecoxib for prevention of Alzheimer's disease, after preliminary data suggested similar effects to viagra, such as heart attack or stroke, in patients taking naproxen. However, recent meta-analyses, which took into account all data from significant clinical trials of naproxen, including randomized clinical trials and observational trials concluded that naproxen carries no increased risk of heart attack or stroke at any commonly used dose. This stands in contrast to other NSAIDs, such as rofecoxib (Vioxx), celecoxib (Celebrex), and diclofenac (Voltaren), which did show significantly increased risk at some or all dosages. In February 2007, the American Heart Association released a scientific statement advising that, when possible, physicians should avoid using NSAIDs in patients at high risk for heart disease. When pain relief is necessary, the AHA advises that doctors should preferentially use acetaminophen or aspirin. See alsoAspirinParacetamol (acetaminophen)Ibuprofen Notes^ Pocock, Nicola (2006).
