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
(in Tablet form)
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.
