Drugs for Osteoarthritis, Drugs used for Rheumatoid Arthritis, Non-steroidal Anti-inflammatory Drugs (NSAIDs)

Like common NSAIDs, dexibuprofen is an active enantiomer of ibuprofen that suppresses the prostanoid synthesis in the inflammatory cells via inhibition of the COX-2 isoform of the arachidonic acid COX. Attenuating the synthesis of prostaglandins and thromboxanes gives the drug three major therapeutic actions. Anti-inflammatory action comes from decreased prostaglandin E2 and prostacyclin leading to decreased vasodilation and oedema that enhances vascular permeability and activity of inflammatory mediators. Decreased prostaglandin levels in the hypothalamus confers the antipyretic effect of the drug. Analgesic effect stems from decreased prostaglandin levels that sensitize the nociceptors to inflammatory mediators at sites of pain and enhance transmission from afferent pain fibers at the spinal cord

The recommended dosage of dexibuprofen is 600 to 900 mg/day, at 2-3 divided doses. Maximum single dose is 400 mg. The dosage can be raised temporarily up to 1200 mg/day in patients with acute disorders or exacerbations.

Drug interactions is noticed with concomitant use of anticoagulant, methotrexate, lithium, corticosteroids, phenytoin, thiazides and thiazide related substances, other NSAIDs and salicylates, digoxin, ciclosporin, tacrolimus, beta blockers and ACE inhibitors.

Dexibuprofen is contraindicated in patients with known hypersensitivity to any ingredient of this preparation or individuals with acute rhinitis, nasal polyps, urticaria or angioneurotic oedema, gastrointestinal ulcer or bleeding

The most common side effects are nausea, vomiting and abdominal pain. Besides these fatigue, drowsiness, headache, dizziness, vertigo, rash, peripheral odema may also occur. Bleeding time may be prolonged.

Pregnancy: no clinical data on exposed pregnancies are available. Lactation: Ibuprofen is slightly excreted in human milk. Breast-feeding is possible with dexibuprofen if dosage is low and the treatment period is short.

Dexibuprofen has a low acute toxicity and patients have survived after single dose as high as 54 g of racemic ibuprofen. Mild symptoms are most common including abdominal pain, nausea, vomiting, lethargy, drowsiness, headache, titinus, nystagmus and ataxia. The onset of symptoms usually occurs within 4 hours. Treatment is symptomatic and there is no specific antidote.

Dexibuprofen should be used with caution in patients with active and suspected gastrointestinal bleeding and bronchial asthma. In heart failure, hypertension, renal or hepatic disease, especially during concomitant diuretic treatment, the risk of fluid retention and deterioration in renal function should be taken into account. In case of elderly patient dexibuprofen should be started with lower dose. In case of hepatic and renal dysfunction it should be started with lower dose. It should not be used in patient with severe hepatic and renal dysfunction.

Store in a cool & dry place protected from light and moisture. Keep out of reach of children.
