PHARMACOLOGICAL CLASSIFICATION:
A 3.1 Antirheumatics (anti-inflammatory agents).

PHARMACOLOGICAL ACTION:
Naproxen is an analgesic, antipyretic and non-steroidal anti-inflammatory. Naproxen inhibits prostaglandin synthetase, however, the exact mechanism of its anti-inflammatory action is not known.

Emergency treatment of acute gout attacks. Treatment of post traumatic conditions such as pain, swelling and inflammation, for a maximum period of 5 days.

CONTRA-INDICATIONS:
A history of or active gastro-intestinal bleeding or peptic ulceration.
Pregnancy and lactation.
Patients who are sensitive to aspirin or other non-steroidal anti-inflammatory agents, since the potential for cross-sensitivity exists.
Not to be used in children under the age of 16 years except when used in juvenile rheumatoid arthritis.

Usual dose is 500 mg to 1 g of naproxen daily in 2 divided doses.

The tablets should be taken with food.

SIDE-EFFECTS AND SPECIAL PRECAUTIONS:
Side-effects which may occur include nausea, vomiting, dyspepsia, constipation, peptic ulceration, gastro-intestinal haemorrhage, insomnia or drowsiness, depression, headache, nervousness, dizziness, tinnitus, pruritus, skin eruptions and angio-oedema, visual disturbances and an increase in bleeding time.
Hypersensitivity reactions, abnormalities of liver function tests, impairment of renal function, agranulocytosis and thrombocytopenia have been observed.
In view of the product’s inherent potential to cause fluid retention, heart failure may be precipitated in some compromised patients.
Naproxen should be given with care to patients with asthma, bronchospasm, bleeding disorders, cardiovascular disease, renal failure and in those who are receiving coumarin anticoagulants (due to naproxen being extensively bound to plasma proteins, an overdosage of coumarin can occur).

Interactions:
Naproxen may inhibit the clearance of lithium, leading to increasing lithium concentrations; Naproxen may inhibit the diuretic and hypotensive effect of furosemide; Naproxen may reduce the secretion of methotrexate, leading to toxicity with methotrexate; Naproxen may interfere with some tests for 17-ketogenic steroids.

KNOWN SYMPTOMS OF OVERDOSAGE AND PARTICULARS OF ITS TREATMENT:
