Sonap® (Naproxen Sodium) is a Non-Steroidal Anti-inflammatory agent. The drug exhibits anti-inflammatory, analgesic, and antipyretic activity by inhibiting prostaglandin synthesis. Both Naproxen and Naproxen Sodium (Sonap) are completely absorbed from the GIT but the peak plasma concentration is attained about 1-2 hours after ingestion of Naproxen Sodium (Sonap) whereas that takes 2-4 hours after ingestion of Naproxen.
Naproxen is indicated for the relief of symptoms of rheumatoid arthritis, both of acute flares and long term management of the disease. It is also used in the diseases of rheumatoid osteoarthritis (degenerative arthritis), ankylosing spondylitis, juvenile rheumatoid arthritis, tendinitis, brusitis, acute gout, acute musculoskeletal disorders (such as sprains, direct trauma and fibrositis), migraine and dysmenorrhoea.
Tablet & Suppository:
Gel:
Sonap® gel is to be applied 2-6 times a day as required and is not recommended for use in children.
Precaution & Contraindications:
Naproxen should be used with caution in patients with cardiac, hepatic and renal impairment, coagulation defect, and previous history of gastro-intestinal ulceration. The drug is contraindicated in patients with a history of hypersensitivity to aspirin or any other NSAID - which includes those in whom attacks of asthma, angioedema, urticaria or rhinitis have been precipitated by aspirin or any other NSAID.
Naproxen suppository in contraindicated in children under 12 years of age. The suppository is contraindicated also in patients with any inflammatory lesions of rectum or anus and in patients with recent history of rectal or anal bleeding.
Use in patients receiving ACE inhibitors may potentiate renal diseases. Drug which are Albumin-bound may be displaced from their binding sites as a result of the naproxen anions’ affinity for protein. Use with caution when given concomitantly with coumarin-type anticoagulants, hydantion sulfonamides, or sulfonylureas. Concomitant administration is not recommended because reduction in the antihypertensive effect of propranolol and other beta-blockers may occur. Concurrent administration of probenecid or methotrexate should be done cautiously to prevent potential naproxen and methotrexate toxicity, respectively.
Pregnancy & Lactation:
There are no well controlled studies in pregnant women. The drug should not be used during pregnancy unless clearly needed. Because of the possible adverse effects of prostaglandin inhibiting drugs on neonates, use in nursing mothers must be avoided.
