Coated tablets, film-coated tablets

Hypersensitivity, erosive-ulcerative lesions of the gastrointestinal tract (in acute phase), “aspirin” triad (combination of bronchial asthma, recurrent polyposis of the nose and sinuses, intolerance to ASA and pyrazolone drugs), bone marrow inhibition, liver and/or kidney failure, pregnancy, lactation, children (under 1 year). Caution. CHF, children (under 16 years).

How to use: dosage and treatment course.
Inside. Tablets should be taken as a whole with fluids, you can take with a meal.

In acute attack of gout the first dose is 825 mg; then it is 275 mg every 8 hours.

In algodysmenorrhea, the first dose is 500 mg, then 275 mg every 6-8 hours for 3-4 days.

In migraine, 500 mg.

Rectal suppositories are usually administered at night (1 suppository of 0.5 g). If it is necessary to use naproxen in high doses, it is possible to combine the prescription in suppositories and in tablets.

Pharmacological action
It has anti-inflammatory, analgesic and antipyretic effects due to non-selective inhibition of COX1 and COX2 activity, which regulate Pg synthesis.

Side effects
NSAID gastropathy (gastric entral lesions in the form of mucosal erythema, hemorrhages, erosions and ulcers).

Nausea, vomiting, discomfort in epigastrium, skin rash, urticaria, angioedema; headache, drowsiness, tinnitus, dizziness, weakness, slowed reaction time; erosive and ulcerative lesions of other gastrointestinal tracts. gastrointestinal tract, bleeding and gastrointestinal perforations; eosinophilic pneumonia; thrombocytopenia, granulocytopenia, aplastic anemia, hemolytic anemia; hearing loss, renal or hepatic dysfunction.Overdose. Symptoms: heartburn, dyspepsia, nausea, vomiting, drowsiness.

Treatment: gastric lavage, activated charcoal – 0.5 g/kg. Dialysis is ineffective.

Special instructions
If it is necessary to determine 17-ketosteroids the drug should be discontinued 48 hours before the study. Liver and kidney functions and peripheral blood composition should be monitored. It should be taken into account that naproxen increases bleeding time.

Simultaneous administration may cause decreased diuretic effect of furosemide; increased effect of indirect anticoagulants.

Increases toxicity of phenytoin, sulfonamides, methotrexate (blocks tubular secretion).

Reduces the hypotensive effect of beta-adrenoblockers.

Decreases the excretion of Li+ and increases its concentration in plasma.

Antacid drugs containing Mg2+ and Al3+ reduce absorption of naproxen.

Myelotoxic drugs increase manifestations of hematotoxicity of the drug.
