Uses
Carefully consider the potential benefits and risks
of NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN Suspension
and other treatment options before deciding to use NAPROSYN, EC-NAPROSYN,
ANAPROX, ANAPROX DS or NAPROSYN Suspension. Use the lowest effective
dose for the shortest duration consistent with individual patient
treatment goals.
Naproxen as
NAPROSYN, EC-NAPROSYN, ANAPROX, ANAPROX DS or NAPROSYN 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 arthritis
Naproxen as NAPROSYN Suspension is recommended for
juvenile rheumatoid arthritis in order to obtain the maximum dosage
flexibility based on the patient's weight.
Naproxen
as NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN 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
EC-NAPROSYN is not recommended for initial treatment
of acute pain because the absorption of naproxen is delayed compared
to absorption from other naproxen-containing products.
History
There is currently no drug history available for this drug.
Other Information
Naproxen is a proprionic acid derivative related to the arylacetic acid group of nonsteroidal anti-inflammatory drugs.
The chemical names for naproxen and naproxen sodium are (S)-6-methoxy-α-methyl-2-naphthaleneacetic acid and (S)-6-methoxy-α-methyl-2-naphthaleneacetic
acid, sodium salt, respectively. Naproxen and naproxen sodium have the following structures, respectively:
Naproxen has a molecular weight of 230.26 and a molecular formula of C14H14O3. Naproxen sodium has a molecular weight
of 252.23 and a molecular formula of C14H13NaO3.
Naproxen is an odorless, white to off-white crystalline substance. It is lipid-soluble, practically
insoluble in water at low pH and freely soluble in water at high pH.
The octanol/water partition coefficient of naproxen at pH 7.4 is 1.6 to 1.8. Naproxen sodium is a white to creamy white, crystalline solid,
freely soluble in water at neutral pH.
NAPROSYN (naproxen tablets) is available as yellow tablets containing 250 mg of naproxen, pink tablets containing 375 mg of naproxen and yellow
tablets containing 500 mg of naproxen for oral administration. The inactive ingredients are croscarmellose sodium, iron oxides,povidone and magnesium stearate.
EC-NAPROSYN
(naproxen delayed-release tablets) is available as enteric-coatedwhite tablets containing 375 mg of naproxen and 500 mg of naproxen
for oral administration. The inactive ingredients are croscarmellose sodium, povidone and magnesium stearate. The enteric coating dispersion
contains methacrylic acid copolymer, talc, triethyl citrate, sodium hydroxide and purified water. The dissolution of this enteric-coated
naproxen tablet is pH dependent with rapid dissolution above pH 6. There is no dissolution below pH 4.
ANAPROX (naproxen sodium tablets) is available as blue tablets containing 275 mg of naproxen sodium and ANAPROX DS (naproxen sodium tablets) for oral administration. The inactive ingredients are croscarmellose sodium, povidone and magnesium stearate. The enteric coating dispersion contains methacrylic acid copolymer, talc, triethyl citrate, sodium hydroxide and purified water.

Carefully consider the potential benefits and risks of NAPROSYN,
EC-NAPROSYN, ANAPROX, ANAPROX DS and NAPROSYN Suspension
and other treatment options before deciding to use NAPROSYN, EC-NAPROSYN,
ANAPROX, ANAPROX DS and NAPROSYN Suspension. Use the lowest effective
dose for the shortest duration consistent with individual patient treatment goals.
After observing the response to initial therapy with NAPROSYN, EC-NAPROSYN,
ANAPROX, ANAPROX DS or NAPROSYN Suspension, the dose and frequency
should be adjusted to suit an individual patient's needs.
Different dose strengths and formulations (ie, tablets, suspension) of the drug are not necessarily
bioequivalent. This difference should be taken into consideration when changing formulation.
Although NAPROSYN, NAPROSYN Suspension, EC-NAPROSYN, ANAPROX and ANAPROX DS
all circulate in the plasma as naproxen, they have pharmacokinetic
differences that may affect onset of action. Onset of pain relief
can begin within 30 minutes in patients taking naproxen sodium and
within 1 hour in patients taking naproxen. Because EC-NAPROSYN dissolves
in the small intestine rather than in the stomach, the absorption
of the drug is delayed compared to the other naproxen formulations.
The recommended strategy for initiating therapy is to choose a formulation and a starting
dose likely to be effective for the patient and then adjust the dosage
based on observation of benefit and/or adverse events. A lower dose
should be considered in patients with renal or hepatic impairment or in elderly patients.
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.
Naproxen-containing products are not recommended
for use in patients with moderate to severe renal impairment
Rheumatoid Arthritis, Osteoarthritis and Ankylosing Spondylitis:
NAPROSYN 250 mg or 375 mg or 500 mg twice daily
275 mg (naproxen 250 mg with 25 mg sodium) twice daily
ANAPROX DS 550 mg (naproxen 500 mg with 50 mg sodium) twice daily
NAPROSYN Suspension 250 mg (10 mL/2 tsp) or 375 mg (15 mL/3 tsp or 500 mg) or (20 mL/4 tsp) twice daily
EC-NAPROSYN 375 mg or 500 mg twice daily.
To maintain the integrity of the enteric coating,
the EC-NAPROSYN tablet should not be broken, crushed or chewed during
ingestion. NAPROSYN Suspension should be shaken gently before use.
During long-term administration, the dose of naproxen
may be adjusted up or down depending on the clinical response of the
patient. A lower daily dose may suffice for long-term administration.
The morning and evening doses do not have to be equal in size and
the administration of the drug more frequently than twice daily is not necessary.
In patients who tolerate lower
doses well, the dose may be increased to naproxen 1500 mg/day for
limited periods of up to 6 months when a higher level of anti-inflammatory/analgesic
activity is required. When treating such patients with naproxen 1500
mg/day, the physician should observe sufficient increased clinical
benefits to offset the potential increased risk. The morning
and evening doses do not have to be equal in size and administration
of the drug more frequently than twice daily does not generally make
a difference in response .
The use of NAPROSYN Suspension is recommended for
juvenile arthritis in children 2 years or older because it allows
for more flexible dose titration based on the child's weight. In pediatric
patients, doses of 5 mg/kg/day produced plasma levels of naproxen
similar to those seen in adults taking 500 mg of naproxen.
The recommended total daily dose
of naproxen is approximately 10 mg/kg given in 2 divided doses (ie,
5 mg/kg given twice a day). A measuring cup marked in 1/2 teaspoon
and 2.5 milliliter increments is provided with the NAPROSYN Suspension.
The following table may be used as a guide for dosing of NAPROSYN
Suspension:Patient's Weight Dose Administered as
13 kg (29 lb) 62.5 mg bid 2.5 mL (1/2 tsp) twice daily
25 kg (55 lb) 125 mg bid 5.0 mL (1 tsp) twice daily
38 kg (84 lb) 187.5 mg bid 7.5 mL (1 1/2 tsp) twice dailyThe recommended starting dose is 550 mg of naproxen
sodium as ANAPROX/ANAPROX DS followed by 550 mg every 12 hours or
275 mg every 6 to 8 hours as required. The initial total daily dose
should not exceed 1375 mg of naproxen sodium. Thereafter, the total
daily dose should not exceed 1100 mg of naproxen sodium. Because the
sodium salt of naproxen is more rapidly absorbed, ANAPROX/ANAPROX
DS is recommended for the management of acute painful conditions when
prompt onset of pain relief is desired. NAPROSYN may also be used
but EC-NAPROSYN is not recommended for initial treatment of acute
pain because absorption of naproxen is delayed compared to other naproxen-containing
products.
The recommended starting dose is 750 mg of NAPROSYN
followed by 250 mg every 8 hours until the attack has subsided. ANAPROX
may also be used at a starting dose of 825 mg followed by 275 mg every
8 hours. EC-NAPROSYN is not recommended because of the delay in absorption
(see CLINICAL PHARMACOLOGY, INDICATIONS
AND USAGE).). -
