The clearance of Naproxen is 0. The plasma half-life of the Naproxen anion in humans ranges from 12 to 17 hours. The corresponding half-lives of both Naproxen's metabolites and conjugates are shorter than 12 hours, and their rates of excretion have been found to coincide closely with the rate of Naproxen disappearance from the plasma.

The terminal half-life appears to be similar in pediatric and adult patients. Pharmacokinetic studies of Naproxen were not performed in pediatric patients younger than 5 years of age.

Pharmacokinetic parameters appear to be similar following administration of Naproxen suspension or tablets in pediatric patients. Unbound trough Naproxen concentrations in elderly subjects have been reported to range from 0.

The clinical significance of this finding is unclear, although it is possible that the increase in free Naproxen concentration could be associated with an increase in the rate of adverse events per a given dosage in some elderly patients. Naproxen pharmacokinetics has not been determined in subjects with hepatic insufficiency. Chronic alcoholic liver disease and probably other diseases with decreased or abnormal plasma proteins albumin reduce the total plasma concentration of Naproxen, but the plasma concentration of unbound Naproxen is increased.

Caution is advised when high doses are required and some adjustment of dosage may be required in these patients. It is prudent to use the lowest effective dose. Naproxen pharmacokinetics has not been determined in subjects with renal insufficiency.

Given that Naproxen, its metabolites and conjugates are primarily excreted by the kidney, the potential exists for Naproxen metabolites to accumulate in the presence of renal insufficiency. Elimination of Naproxen is decreased in patients with severe renal impairment. The clinical significance of this interaction is not known. Naproxen has been studied in patients with rheumatoid arthritis, osteoarthritis, juvenile arthritis, ankylosing spondylitis, tendonitis and bursitis, and acute gout. Improvement in patients treated for rheumatoid arthritis was demonstrated by a reduction in joint swelling, a reduction in duration of morning stiffness, a reduction in disease activity as assessed by both the investigator and patient, and by increased mobility as demonstrated by a reduction in walking time.

Generally, response to Naproxen has not been found to be dependent on age, sex, severity or duration of rheumatoid arthritis. In patients with osteoarthritis, the therapeutic action of Naproxen has been shown by a reduction in joint pain or tenderness, an increase in range of motion in knee joints, increased mobility as demonstrated by a reduction in walking time, and improvement in capacity to perform activities of daily living impaired by the disease.

Nineteen patients in the mg group terminated prematurely because of adverse events. Most of these adverse events were gastrointestinal events.

In clinical studies in patients with rheumatoid arthritis, osteoarthritis, and juvenile arthritis, Naproxen has been shown to be comparable to aspirin and indomethacin in controlling the aforementioned measures of disease activity, but the frequency and severity of the milder gastrointestinal adverse effects nausea, dyspepsia, heartburn and nervous system adverse effects tinnitus, dizziness, lightheadedness were less in Naproxen-treated patients than in those treated with aspirin or indomethacin.

In patients with ankylosing spondylitis, Naproxen has been shown to decrease night pain, morning stiffness and pain at rest. In double-blind studies the drug was shown to be as effective as aspirin, but with fewer side effects. In patients with acute gout, a favorable response to Naproxen was shown by significant clearing of inflammatory changes e. Naproxen has been studied in patients with mild to moderate pain secondary to postoperative, orthopedic, postpartum episiotomy and uterine contraction pain and dysmenorrhea.

Onset of pain relief can begin within 1 hour in patients taking Naproxen. Analgesic effect was shown by such measures as reduction of pain intensity scores, increase in pain relief scores, decrease in numbers of patients requiring additional analgesic medication, and delay in time to remedication.

The analgesic effect has been found to last for up to 12 hours. Whether Naproxen has a "steroid-sparing" effect has not been adequately studied. When added to the regimen of patients receiving gold salts, Naproxen did result in greater improvement. Its use in combination with salicylates is not recommended because there is evidence that aspirin increases the rate of excretion of Naproxen and data are inadequate to demonstrate that Naproxen and aspirin produce greater improvement over that achieved with aspirin alone.

In addition, as with other NSAIDs, the combination may result in higher frequency of adverse events than demonstrated for either product alone. In 51 Cr blood loss and gastroscopy studies with normal volunteers, daily administration of mg of Naproxen has been demonstrated to cause statistically significantly less gastric bleeding and erosion than mg of aspirin.

The hepatic and renal tolerability of long-term Naproxen administration was studied in two double-blind clinical trials involving patients. Of the patients studied, 98 patients were age 65 and older and 10 of the 98 patients were age 75 and older. Naproxen was administered at doses of mg twice daily or mg twice daily for up to 6 months. Transient abnormalities of laboratory tests assessing hepatic and renal function were noted in some patients, although there were no differences noted in the occurrence of abnormal values among different age groups.

Carefully consider the potential benefits and risks of Naproxen Suspension and other treatment options before deciding to use Naproxen Suspension. Naproxen Suspension is recommended for juvenile rheumatoid arthritis in order to obtain the maximum dosage flexibility based on the patient's weight.

Clinical trials of several COX-2 selective and nonselective NSAIDs of up to three years duration have shown an increased risk of serious cardiovascular CV thrombotic events, including myocardial infarction MI , and stroke, which can be fatal.

However, patients with known CV disease or risk factors had a higher absolute incidence of excess serious CV thrombotic events, due to their increased baseline rate. Some observational studies found that this increased risk of serious CV thrombotic events began as early as the first weeks of treatment.

The increase in CV thrombotic risk has been observed most consistently at higher doses. To minimize the potential risk for an adverse CV event in NSAID-treated patients, use the lowest effective dose for the shortest duration possible. Physicians and patients should remain alert for the development of such events, throughout the entire treatment course, even in the absence of previous CV symptoms.

Patients should be informed about the 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.

Observational studies conducted in the Danish National Registry have demonstrated that patients treated with NSAIDs in the post-MI period were at increased risk of reinfarction, CV-related death, and all-cause mortality beginning in the first week of treatment. Although the absolute rate of death declined somewhat after the first year post-MI, the increased relative risk of death in NSAID users persisted over at least the next 4 years of follow-up.

Avoid the use of Naproxen Suspension in patients with a recent MI unless the benefits are expected to outweigh the risk of recurrent CV thrombotic events. If Naproxen Suspension is used in patients with a recent MI, monitor patients for signs of cardiac ischemia. NSAIDs, including Naproxen, can cause serious gastrointestinal GI adverse events including inflammation, bleeding, ulceration, and perforation of the esophagus, stomach, small intestine, or large intestine, which can be fatal.

These serious adverse events can occur at any time, with or without warning symptoms, in patients treated with NSAIDs. However, even short-term therapy is not without risk. Other factors that increase the risk of GI bleeding in patients treated with NSAIDs include longer duration of NSAID therapy; concomitant use of oral corticosteroids, aspirin, anticoagulants, or selective serotonin reuptake inhibitors SSRIs , smoking, use of alcohol, older age, and poor general health status.

Most postmarketing reports of fatal GI events occurred in elderly or debilitated patients. In addition, rare, sometimes fatal, cases of severe hepatic injury, including fulminant hepatitis, liver necrosis and hepatic failure have been reported. Inform patients of the warning signs and symptoms of hepatotoxicity e. If clinical signs and symptoms consistent with liver disease develop, or if systemic manifestations occur e. NSAIDs, including Naproxen Suspension, can lead to new onset of hypertension or worsening of pre-existing hypertension, either of which may contribute to the increased incidence of CV events.

The Coxib and traditional NSAID Trialists' Collaboration meta-analysis of randomized controlled trials demonstrated an approximately two-fold increase in hospitalizations for heart failure in COX-2 selective-treated patients and nonselective NSAID-treated patients compared to placebo-treated patients.

Use of Naproxen may blunt the CV effects of several therapeutic agents used to treat these medical conditions [e. Avoid the use of Naproxen Suspension in patients with severe heart failure unless the benefits are expected to outweigh the risk of worsening heart failure. If Naproxen Suspension is used in patients with severe heart failure, monitor patients for signs of worsening heart failure.

Each 5 mL of Naproxen Suspension contains 39 mg of sodium. This should be considered in patients whose overall intake of sodium must be severely restricted. 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 an 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, dehydration, hypovolemia, heart failure, liver dysfunction, those taking diuretics and ACE inhibitors or ARBs, and the elderly.

No information is available from controlled clinical studies regarding the use of Naproxen Suspension in patients with advanced renal disease. The renal effects of Naproxen Suspension may hasten the progression of renal dysfunction in patients with pre-existing renal disease.

Correct volume status in dehydrated or hypovolemic patients prior to initiating Naproxen Suspension. Avoid the use of Naproxen Suspension in patients with advanced renal disease unless the benefits are expected to outweigh the risk of worsening renal function.

If Naproxen Suspension is used in patients with advanced renal disease, monitor patients for signs of worsening renal function. Increases in serum potassium concentration, including hyperkalemia, have been reported with use of NSAIDs, even in some patients without renal impairment.

In patients with normal renal function, these effects have been attributed to a hyporeninemic-hypoaldosteronism state. When Naproxen Suspension is used in patients with preexisting asthma without known aspirin sensitivity , monitor patients for changes in the signs and symptoms of asthma. These serious events may occur without warning. Inform patients about the signs and symptoms of serious skin reactions and to discontinue use of Naproxen Suspension at the first appearance of skin rash or any other sign of hypersensitivity.

Naproxen may cause premature closure of the fetal ductus arteriosus. This may be due to occult or gross blood loss, fluid retention, or an incompletely described effect on erythropoiesis. If a patient treated with Naproxen Suspension has any signs or symptoms of anemia, monitor hemoglobin or hematocrit. Co-morbid conditions such as coagulation disorders, or concomitant use of warfarin, other anticoagulants, antiplatelet agents e.

Naproxen Suspension should not be used concomitantly with other Naproxen-containing products since they all circulate in the plasma as the Naproxen anion.

Naproxen Suspension cannot be expected to substitute for corticosteroids or to treat corticosteroid insufficiency. Abrupt discontinuation of corticosteroids may lead to disease exacerbation. Patients on prolonged corticosteroid therapy should have their therapy tapered slowly if a decision is made to discontinue corticosteroids and the patient should be observed closely for any evidence of adverse effects, including adrenal insufficiency and exacerbation of symptoms of arthritis.

Patients with initial hemoglobin values of 10 g or less who are to receive long-term therapy should have hemoglobin values determined periodically. Because of adverse eye findings in animal studies with drugs of this class, it is recommended that ophthalmic studies be carried out if any change or disturbance in vision occurs.

Advise the patient to read the FDA-approved patient labeling Medication Guide that accompanies each prescription dispensed. Inform patients, families, or their caregivers of the following information before initiating therapy with Naproxen Suspension and periodically during the course of ongoing therapy. Advise patients to be alert for the symptoms of cardiovascular thrombotic events, including chest pain, shortness of breath, weakness, or slurring of speech, and to report any of these symptoms to their healthcare provider immediately see WARNINGS; Cardiovascular Thrombotic Events.

Advise patients to report symptoms of ulcerations and bleeding, including epigastric pain, dyspepsia, melena, and hematemesis to their health care provider. Advise patients to be alert for the symptoms of congestive heart failure including shortness of breath, unexplained weight gain, or edema and to contact their healthcare provider if such symptoms occur see WARNINGS; Heart Failure and Edema.

Inform patients of the signs of an anaphylactic reaction e. Alert patients that NSAIDs may be present in "over the counter" medications for treatment of colds, fever, or insomnia. Caution should be exercised by patients whose activities require alertness if they experience drowsiness, dizziness, vertigo or depression during therapy with Naproxen. The pharmacological activity of Naproxen in reducing inflammation, and possibly fever, may diminish the utility of diagnostic signs in detecting infections.

See Table 1 for clinically significant drug interactions with Naproxen. No evidence of tumorigenicity was found. Studies to evaluate the mutagenic potential of Naproxen Suspension have not been completed. Studies to evaluate the impact of Naproxen on male or female fertility have not been completed.

Use of NSAIDs, including Naproxen Suspension, during the third trimester of pregnancy increases the risk of premature closure of the fetal ductus arteriosus. Data from observational studies regarding potential embryofetal risks of NSAID use in women in the first or second trimesters of pregnancy are inconclusive. In the general U. In animal reproduction studies in rats, rabbit, and mice no evidence of teratogenicity or fetal harm when Naproxen was administered during the period of organogenesis at doses 0.

Based on animal data, prostaglandins have been shown to have an important role in endometrial vascular permeability, blastocyst implantation, and decidualization. In animal studies, administration of prostaglandin synthesis inhibitors such as Naproxen, resulted in increased pre- and post-implantation loss.

There is some evidence to suggest that when inhibitors of prostaglandin synthesis are used to delay preterm labor there is an increased risk of neonatal complications such as necrotizing enterocolitis, patent ductus arteriosus and intracranial hemorrhage. Naproxen treatment given in late pregnancy to delay parturition has been associated with persistent pulmonary hypertension, renal dysfunction and abnormal prostaglandin E levels in preterm infants.

Because of the known effects of nonsteroidal antiinflammatory drugs on the fetal cardiovascular system closure of ductus arteriosus , use during pregnancy particularly starting at 30 weeks of gestation, or third trimester should be avoided.

In animal studies, administration of prostaglandin synthesis inhibitors such as Naproxen, resulted in increased preand post-implantation loss. There are no studies on the effects of Naproxen Suspension during labor or delivery. In animal studies, NSAIDS, including Naproxen, inhibit prostaglandin synthesis, cause delayed parturition, and increase the incidence of stillbirth.

The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Naproxen Suspension and any potential adverse effects on the breastfed infant from the Naproxen Suspension or from the underlying maternal condition. Based on the mechanism of action, the use of prostaglandin-mediated NSAIDs, including Naproxen Suspension, may delay or prevent rupture of ovarian follicles, which has been associated with reversible infertility in some women.

Published animal studies have shown that administration of prostaglandin synthesis inhibitors has the potential to disrupt prostaglandin- mediated follicular rupture required for ovulation. Consider withdrawal of NSAIDs, including Naproxen Suspension, in women who have difficulties conceiving or who are undergoing investigation of infertility.. Safety and effectiveness in pediatric patients below the age of 2 years have not been established. There are no adequate effectiveness or dose-response data for other pediatric conditions, but the experience in juvenile arthritis and other use experience have established that single doses of 2.

Studies indicate that although total plasma concentration of Naproxen is unchanged, the unbound plasma fraction of Naproxen is increased in the elderly. Caution is advised when high doses are required and some adjustment of dosage may be required in elderly patients.

As with other drugs used in the elderly, it is prudent to use the lowest effective dose. Experience indicates that geriatric patients may be particularly sensitive to certain adverse effects of nonsteroidal anti-inflammatory drugs.

Elderly or debilitated patients seem to tolerate peptic ulceration or bleeding less well when these events do occur. Naproxen is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function.

Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.
