Clinical Studies General Information 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 51Cr 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. Geriatric Patients 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.

Indications and Usage for Naproxen Carefully consider the potential benefits and risks of Naproxen Suspension and other treatment options before deciding to use Naproxen Suspension. Naproxen Suspension is indicated: For the relief of the signs and symptoms of rheumatoid arthritis For the relief of the signs and symptoms of osteoarthritis For the relief of the signs and symptoms of ankylosing spondylitis For the relief of the signs and symptoms of juvenile rheumatoid arthritis Naproxen Suspension is recommended for juvenile rheumatoid arthritis in order to obtain the maximum dosage flexibility based on the patient's weight.

Naproxen Suspension is also indicated: For relief of the signs and symptoms of tendonitis For relief of the signs and symptoms of bursitis For relief of the signs and symptoms of acute gout For the management of pain For the management of primary dysmenorrhea Contraindications Naproxen Suspension is contraindicated in the following patients: 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.

Jennifer Carey, PharmD Q: I've recently started suffering from osteoarthritis and have discovered that taking naproxen every day seems to keep the pain in check. What are the short- and long-term risks involved in taking naproxen every day?

Over-the-counter medications for pain include non-steroidal anti-inflammatory drugs NSAIDs and the analgesic Tylenol acetaminophen. Doses of to mg every 4 to 6 hours or mg daily can be used over the counter. Naproxen can be taken at doses of mg every 12 hours.

NSAIDs should be avoided in patients with kidney or liver disease, patients with heart disease or a history of stomach ulcer or bleeding. Aspirin can also be considered an NSAID, but it should not be used in doses high enough to treat pain without the direction of a physician due to bleeding risks. Tylenol is an analgesic used to treat mild to moderate pain and fever.

The maximum daily dose of Tylenol is mg 4 grams daily. It is important to note that some prescription pain medications or cough and cold medications also contain acetaminophen.

It is important to not take more than 4 grams of acetaminophen a day from all sources. Tylenol can affect the liver, so patients who already have liver damage should avoid taking Tylenol. Patients who drink more than 3 alcoholic drinks a day should also avoid taking Tylenol due to the increased risk of liver damage.

There are also many prescription pain medications available for moderate to severe pain that cannot be treated with an over-the-counter medication.

Renal and urinary disorders: Nephropathy and nephrotoxicity in various forms, including but not limited to glomerular nephritis, interstitial nephritis, nephrotic syndrome, haematuria, raised serum creatinine, renal papillary necrosis and renal failure.

Abnormal liver function tests, fatal hepatitis and jaundice. Blood and lymphatic system disorders: Granulocytopenia, thrombocytopenia, neutropenia, agranulocytosis, eosinophilia, leucopenia, aplastic anaemia and haemolytic anaemia.

Skin and subcutaneous tissue disorders: Skin rashes including fixed drug eruption, itching pruritus , urticaria, ecchymoses, purpura, sweating. If skin fragility, blistering or other symptoms suggestive of pseudoporphyria occur, treatment should be discontinued and the patient monitored.

Musculoskeletal and connective tissue disorders: Myalgia and muscle weakness. Reproductive system and breast disorders: General disorders and administration site conditions: Thirst, pyrexia, fatigue and malaise.

In one case of naproxen overdose, transient prolongation of the prothrombin time due to hypothrombinaemia may have been due to selective inhibition of the synthesis of vitamin-K dependent clotting factors.

A few patients have experienced seizures, but it is not known whether these were naproxen-related or not. It is not known what dose of the drug would be life-threatening. Should a patient ingest a large amount of naproxen, the stomach may be emptied and usual supportive measures employed it is not known what dose of drug would be life threatening.

Within one hour of ingestion of a potentially toxic amount, activated charcoal should be considered. Alternatively, in adults, gastric lavage should be considered within one hour of ingestion of a potentially life-threatening overdose.

Good urine output should be ensured. Renal and liver function should be closely monitored. Patients should be observed for at least four hours after ingestion of potentially toxic amounts.

Frequent or prolonged convulsions should be treated with intravenous diazepam. Other measures may be indicated by the patient's clinical condition.

Pharmacological properties Pharmacotherapeutic group: M01AE02 Naproxen is a non-steroidal anti-inflammatory analgesic compound with antipyretic properties as has been demonstrated in classical animal test systems.

Naproxen exhibits its anti-inflammatory effect even in adrenalectomised animals, indicating that its action is not mediated through the pituitary-adrenal axis. Naproxen is present in the blood mainly as unchanged drug, extensively bound to plasma proteins. The plasma half-life is between 12 and 15 hours, enabling a steady state to be achieved within 3 days of initiation of therapy on a twice daily dose regimen.

The degree of absorption is not significantly affected by either foods or most antacids. Excretion is almost entirely via the urine, mainly as conjugated naproxen, with some unchanged drug. Metabolism in children is similar to that in adults. Chronic alcoholic liver disease reduces the total plasma concentration of naproxen but the concentration of unbound naproxen increases.

In the elderly, the unbound plasma concentration of naproxen is increased although total plasma concentration is unchanged. Naproxen was not carcinogenic in rats.

Mutagenicity Mutagenicity was not seen in Salmonella typhimurium 5 cell lines , Sachharomyces cerevisisae 1 cell line and mouse lymphoma tests. These are known effects of this class of compounds and were demonstrated in pregnant rats with aspirin and indometacin.
