Naproxen, (ALEVE, NAPROSYN, others), is absorbed fully when administered orally. Food delays the rate but not the extent of absorption. Peak concentrations in plasma occur within 2-4 hours and are somewhat more rapid after the administration of naproxen sodium. Absorption is accelerated by the concurrent administration of sodium bicarbonate but delayed by magnesium oxide or aluminum hydroxide. Naproxen also is absorbed rectally, but more slowly than after oral administration. The ty2 of naproxen is -14 hours in the young it may increase about twofold in the elderly because of age-related decline in renal function (Table 26—1). 

Tablets 220 mg naproxen (Aleve), 250 mg (Naprosyn), 275 mg naproxen sodium (equivalent to 250 mg naproxen) (Anaprox), 550 mg naproxen sodium (equivalent to 500 mg naproxen) (Aflaxen, Anaprox DS). 

Naproxen is a chemical cousin of ibuprofen. Both are derived from a chemical called propionic acid. Common brand names of naproxen in the United States are Aleve , Anaprox , Naprelan , and Naprosyn . Like ibuprofen, naproxen is an NSAID that inhibits the COX enzyme and reduces pain, fever, and inflammation. The advantage of using naproxen instead of ibuprofen is that naproxen remains in the blood longer (8-12 hours... 

Pain killers and anti-inflammatory agents may also cause a problem. Watch out for acetaminophen (Tylenol), naproxen (OTC Aleve or Rx Naprosyn), and ibuprofen (Advil, Motrin). The prescription-only anti-inflammatory drugs diclofenac (Voltaren) and indomethacin (Indocin) can also increase blood pressure. 

S)-Naproxen is the aaive ingredient in the widely used pain relievers Naprosyn and Aleve. The three-dimensional orientation of two atoms at a single carbon in naproxen determines its therapeutic properties. Changing the position of these two atoms converts this anti-inflammatory agent into a liver toxin. In Chapter 5 we learn more about stereochemistry and how small structural differences can have a large effect on the properties of a molecule.

The search for NSAIDS that are more effective and yet gentler on the stomach has provided two new analgesics for the over-the-counter market. These are ibuprofen (sold as Motrin, Advil, Nuprin) and naproxen (sold as Naprosyn, Naprelan, Anaprox, and Aleve). 

Like aspirin, both ibuprofen and naproxen are relatively simple aromatic compounds containing a side-chain carboxylic acid group. Ibuprofen, sold under the names Advil, Nuprin, Motrin, and others, has roughly the same potency as aspirin but is less prone to cause stomach upset. Naproxen, sold under the names Aleve and Naprosyn, also has about the same potency as aspirin but remains active in the body six times longer.
