Naproxen was first and 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.

Structure and details

Naproxen 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, practically insoluble in water with a low pH (below pH 4), while freely soluble in water at 6 pH and above. It has a melting point of 153 °C. A polyunsaturated triglyceride. ... The correct title of this article is . ... The melting point of a crystalline solid is the temperature at which it changes state from solid to liquid. ... Celsius is, or relates to, the Celsius temperature scale (previously known as the centigrade scale). ...


Adverse effects and warnings

Like other NSAIDs, naproxen is capable of producing disturbances in the gastrointestinal tract. Addition of a proton pump inhibitor such as esomeprazole will prevent this adverse effect. Naproxen in combination with a proton pump inhibitor is the safest NSAID combination. Upper and Lower gastrointestinal tract The gastrointestinal tract (GI tract), also called the digestive tract, or the alimentary canal, is the system of organs within multicellular animals that takes in food, digests it to extract energy and nutrients, and expels the remaining waste. ... Proton pump inhibitors (or PPIs) are a group of drugs whose main action is pronounced and long-lasting reduction of gastric acid production. ... Esomeprazole is a proton pump inhibitor used in the treatment of dyspepsia, peptic ulcer disease (PUD), GERD and Zollinger-Ellison syndrome. ... An adverse drug reaction (abbreviated ADR) is a term to describe the unwanted, negative consequences sometimes associated with the use of medications. ...


Also 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 (drugs may reduce each other's effects), nor with anticoagulants (may increase risk of bleeding). Certain preparations of naproxen are not recommended for use in patients with hypertension, as they contain sodium, worsening the effects of hypertension.

In August 2006, the journal Birth Defects Research Part B published results in the September issue 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.


Risk of heart attack or stroke

The National Institutes of Health prematurely terminated a randomized clinical trial of naproxen and celecoxib for prevention of Alzheimer's disease, after preliminary data suggested an increased risk of major cardiovascular events, 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, which did show significantly increased risk at some or all dosages. In February of 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 certain older, non-COX-2 selective NSAIDs.
