Description

Indications/Uses

For the symptomatic relief of rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, tendinitis, bursitis, and acute gout.
For the management of pain including headache, migraine, post-operative pain, post-partum pain, and primary dysmenorrhea.
 

Dosage/Direction for Use

As with other NSAIDs, the lowest effective dose should be used for the shortest possible time.
This medicine is given orally and preferably taken with or after food.
Recommended Adult Dose: One tablet twice a day, or, as prescribed by a physician.
Do not exceed 2 tablets in each 24-hour period.
Use only as directed by a physician.
 

Overdosage

Symptoms of Naproxen overdosage may include lethargy, dizziness, drowsiness, epigastric pain, abdominal discomfort, heartburn, indigestion, nausea, transient alterations in liver function, hypoprothrombinemia, renal dysfunction, metabolic acidosis, apnea, disorientation, and vomiting. Gastrointestinal bleeding, hypertension, acute renal failure, respiratory depression, and coma may also occur. Anaphylactoid reactions may also occur following an overdose. Because high levels of Naproxen Sodium may be rapidly absorbed, high and early blood levels should be anticipated. Convulsions which may or may not be drug-related have also been reported.
Manage overdosage by symptomatic and supportive care. Hemodialysis will not decrease Naproxen plasma concentration because it is highly protein-bound. Patients seen within 4 hours of ingestion may be treated with emesis and/or activated charcoal (60 to 100 g in adults, 1 to 2 g/kg body weight in children) and/or osmotic cathartic. As with hemodialysis, forced diuresis, alkalinization of urine or hemoperfusion may not be useful due to high protein binding.
 

Administration

Should be taken with food.
 

Contraindications

Hypersensitivity to Naproxen Sodium, aspirin or other NSAIDs, or to any ingredient in the product.
Patients who have experienced asthma, urticaria, or allergic reactions after taking aspirin or other NSAIDs. Severe, rarely fatal, anaphylactoid reactions to NSAIDs have been reported in such patients.
Patients with active or a history of peptic/gastrointestinal (GI) ulcers, chronic dyspepsia, bleeding or perforation related to previous NSAID therapy.
Patients with active or a history of recurrent peptic ulcer/hemorrhage (2 or more distinct episodes of proven ulceration or bleeding) unrelated to previous NSAID therapy.
Patients with severe renal, hepatic or cardiac failure.
During the last trimester of pregnancy.
Contraindicated in the treatment of perioperative pain in the setting of coronary artery bypass graft (CABG) surgery.
 

Special Precautions

Cardiovascular Risk: Naproxen may cause an increased risk of serious cardiovascular thrombotic events, myocardial infarction and stroke, which can be fatal. All NSAIDs may have a similar risk. The risk may increase with duration of use. Patients with cardiovascular disease or risk factors for cardiovascular disease may be at greater risk.
Gastrointestinal Risk: NSAIDs, including Naproxen, cause an increased risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients are at greater risk for serious gastrointestinal events.
Cardiovascular Effects: Cardiovascular Thrombotic Events: Clinical trials using COX-2 selective and nonselective NSAIDs of up to three years duration have shown an increased risk of serious cardiovascular (CV) thrombotic events, myocardial infarction and stroke, which can be fatal. Patients with known CV disease or risk factors for CV disease may be at greater risk. To minimize the potential risk for an adverse CV event in patients treated with an NSAID, the lowest effective dose should be used for the shortest duration possible. Physicians and patients should be alert for the development of such events, even in the absence of previous CV symptoms. Patients should be informed on the signs and/or symptoms of serious CV events and the steps to take if they occur.
There is no consistent evidence that concurrent use of aspirin mitigates the increased risk of serious CV thrombotic events associated with NSAID use. The concurrent use of aspirin and an NSAID does increase the risk of serious GI events.
Hypertension: NSAIDs can lead to the onset of new hypertension or worsening of preexisting hypertension, either of which may contribute to the increased incidence of CV events. Patients taking thiazides or loop diuretics may have impaired response to these therapies when taking NSAIDs. NSAIDs, including Naproxen, should be used with caution in patients with hypertension. Blood pressure should be monitored closely during the initiation of NSAID treatment and throughout the course of therapy.
Congestive Heart Failure and Edema: Fluid retention and edema (including peripheral edema) have been seen in some patients taking NSAIDs. Use Naproxen Sodium with caution in patients with fluid retention, hypertension or heart failure. It is important to consider the sodium content of Naproxen Sodium (each tablet of Naproxen Sodium 550 mg contains 50 mg of sodium) in patients whose overall intake of sodium must be severely restricted.
Gastrointestinal Effects: NSAIDs, including Naproxen, can cause serious gastrointestinal adverse events including inflammation, bleeding, ulceration, and perforation of the stomach, small or large intestines, which can be fatal. These serious adverse events can occur at any time, with or without warning symptoms, in patients treated with NSAIDs.
NSAIDs should be prescribed with extreme caution in those with a history of ulcer disease or gastrointestinal bleeding since these patients have a greater than 10-fold increased risk for developing a GI bleed compared with patients with neither of these risk factors.
Other factors that increase the risk for GI bleeding in patients treated with NSAIDs include concomitant use of oral corticosteroids or anticoagulants, longer duration of NSAID therapy, smoking, use of alcohol, older age and poor general health status. Elderly patients, in particular, are at greater risk for serious gastrointestinal events.
The lowest effective dose should be used for the shortest possible duration to minimize the potential risk for an adverse GI event.
Physicians and patients should remain alert for signs and symptoms of GI ulceration and bleeding during NSAID therapy and promptly initiate additional evaluation and treatment if a serious GI adverse event is suspected. This should include discontinuation of the NSAID until a serious GI adverse event is ruled out. Alternate therapies that do not involve NSAIDs should be considered especially for high-risk patients.
Renal Effects: Long-term administration of NSAIDs has resulted in renal papillary necrosis and other renal injury. Renal toxicity has also been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion. In these patients, administration of a NSAID may cause a dose-dependent reduction in prostaglandin formation and secondarily, in renal blood flow, which may precipitate overt renal decompensation. Patients at greatest risk of this reaction are those with impaired renal function, hypovolemia heart failure, liver dysfunction, salt depletion, those taking diuretics and angiotensin converting enzyme (ACE) inhibitors, and the elderly.
Discontinuation of NSAID therapy is usually followed by recovery to the pretreatment state.
Advanced Renal Disease: Naproxen sodium is not recommended in patients with advanced renal disease.
Anaphylactoid Reactions (see Contraindications): Anaphylactoid reactions may occur in patients without known prior exposure to NSAIDs. Naproxen should not be given to patients with the aspirin triad. This symptom complex typically occurs in asthmatic patients who experience rhinitis with or without nasal polyps, or who exhibit severe, potentially fatal bronchospasm after taking aspirin or other NSAIDs. Naproxen should be administered with caution in patients with preexisting asthma and emergency help should be sought in cases where an anaphylactoid reaction occurs.
Skin Reactions: As with other NSAIDs, Naproxen can cause serious skin adverse events such as exfoliative dermatitis, Stevens-Johnson Syndrome (SJS) and toxic epidermal necrolysis (TEN), which can be fatal. These serious events may occur without warning. Patients should be informed about the signs and symptoms of serious skin manifestations and use of the drug should be discontinued at the first appearance of skin rash or any other sign of hypersensitivity.
Hepatic Effects: Borderline elevations of one or more liver tests may occur in up to 15% of patients taking NSAIDs including Naproxen. Hepatic abnormalities may be the result of hypersensitivity rather than direct toxicity. These laboratory abnormalities may progress, may remain unchanged, or may be transient with continued therapy. Notable elevations of alanine aminotransferase (ALT) or aspartate aminotransferase (AST), approximately three or more times the upper limit of normal, have been reported in approximately 1% of patients. Rare cases of severe hepatic reactions, including jaundice and fatal fulminant hepatitis, liver necrosis and hepatic failure, some with fatal outcomes have been reported.
Patients with symptoms and/or signs suggesting liver dysfunction, or in whom an abnormal liver test has occurred, should be evaluated for evidence of the development of a more severe hepatic reaction while on therapy with NSAIDs including Naproxen. Discontinue Naproxen if clinical signs and symptoms consistent with liver disease develop or if systemic manifestations occur (e.g., eosinophilia, rash).
While chronic alcoholic liver disease and probably other diseases which cause decreased or abnormal plasma proteins (albumin) reduce the total plasma concentration of Naproxen, it increases the plasma concentration of unbound Naproxen. Dosage adjustment of Naproxen Sodium may be necessary in these patients. The lowest effective dose is recommended.
Hematologic Effects: Anemia is sometimes seen in patients receiving NSAIDs, including Naproxen. This may be due to fluid retention, occult or gross GI blood loss or an incompletely described effect on erythropoiesis. Patients on long-term treatment with NSAIDs, including Naproxen, should have their hemoglobin or hematocrit checked if they exhibit any signs or symptoms of anemia.
In some patients, NSAIDs inhibit platelet aggregation and have been shown to prolong bleeding time. Unlike aspirin, their effect on platelet function is quantitatively less, of short duration and reversible. Patients receiving Naproxen who may be adversely affected by alterations in platelet function, such as those with coagulation disorders or patients receiving anticoagulants, should be carefully monitored.
General Precautions: Naproxen and other Naproxen-containing products should not be used concomitantly since they all circulate in the plasma as the Naproxen anion.
Naproxen Sodium is not a corticosteroid substitute and cannot be used to treat corticosteroid insufficiency.
Patients with initial hemoglobin values of 10 g or less who are to receive long-term therapy should have hemoglobin values determined periodically.
The antipyretic and anti-inflammatory action of Naproxen Sodium may diminish the use of these diagnostic signs in detecting complications of presumed non-infectious, non-inflammatory painful conditions.
Ophthalmic studies are recommended if any change or disturbance in vision occurs. Adverse eye findings have been seen in animal studies with drugs of this class.
Use in Children: Naproxen Sodium 550 mg tablet is not recommended for pediatric use.
Use in the Elderly: The unbound plasma fraction of naproxen is increased in geriatric patients. Naproxen Sodium should be given with caution to elderly patients when high doses are required; some dosage adjustments are needed. It is prudent to use the lowest effective dose when treating elderly patients. The elderly have less tolerance for gastrointestinal ulceration and bleeding. Many spontaneous reports of fatal adverse gastrointestinal effects associated with NSAIDs invoke geriatric patients.
 

Use In Pregnancy & Lactation

Use in Pregnancy: Pregnancy Category C. Reproductive studies conducted in rats and rabbits have not demonstrated evidence of developmental abnormalities. However, animal reproduction studies are not always predictive of human response. There are no adequate and well-controlled studies in pregnant women.
Naproxen use during pregnancy (particularly the last trimester) is not recommended because of the known effects of NSAIDs on the fetal cardiovascular system (closure of ductus arteriosus).
Use in Lactation: Naproxen is distributed into the milk of lactating women. Naproxen use should be avoided in breastfeeding women to prevent possible adverse effects.

Drug Interactions

See table.



Laboratory Test Interaction: When bleeding times are determined, keep in mind that naproxen may decrease platelet aggregation and prolong bleeding time.
Naproxen may increase urinary values of 17-ketogenic steroids due to its interaction with the M-dinitrobenzene used in the assay. Discontinue naproxen therapy temporarily for 72 hours before adrenal function tests are performed if the Porter-Silber test is to be used.
Interference with urinary assays of 5-hydroxy indoleacetic acid may also be caused by naproxen.
 

Storage

Store at temperatures not exceeding 30°C.
 

Action

Pharmacology: Pharmacodynamics: Naproxen Sodium is a non-steroidal anti-inflammatory drug (NSAID) that exhibits anti-inflammatory, analgesic and antipyretic activity by inhibiting cyclooxygenase (COX)-1 and COX-2 isoenzymes resulting in inhibition of prostaglandin synthesis.
Pain relief with Naproxen Sodium usually begins within 30 minutes compared with 1 hour for plain Naproxen.
Pharmacokinetics: Naproxen and Naproxen Sodium are readily absorbed from the gastrointestinal tract with Naproxen Sodium dissolving more rapidly in gastric juice than plain Naproxen. Thus, Naproxen Sodium is more rapidly absorbed with peak plasma concentrations occurring about 1 to 2 hours after oral administration compared with 2 to 4 hours for naproxen. Naproxen Sodium's oral bioavailability is 95%. The rate but not the extent of absorption is decreased when Naproxen or Naproxen Sodium is taken with food.
Naproxen has a volume of distribution of 0.16 L/kg and is more than 99% plasma protein bound. Naproxen plasma concentrations increase proportionately with doses up to 500 mg daily. Increased clearance due to saturation of plasma proteins is seen at higher doses. Naproxen diffuses into synovial fluid, crosses the placenta and is also distributed in small amounts into breast milk. Naproxen's plasma half-life is about 13 hours.
Naproxen is extensively metabolized in the liver with about 95% of a dose excreted in the urine as Naproxen and 6-desmethylnaproxen and their conjugates and less than 5% of a dose is excreted in the feces.
