Logout 250mg Capsule SR contains Allopurinol 250mg, a xanthine oxidase inhibitor used primarily in the management of hyperuricemia and gout. Allopurinol works by reducing the production of uric acid, thereby preventing the formation of urate crystals that cause joint inflammation and pain. It is indicated for the treatment of chronic gout, recurrent calcium oxalate kidney stones, and hyperuricemia associated with malignancy or chemotherapy. The sustained-release (SR) formulation ensures a gradual release of the active ingredient, providing prolonged therapeutic effects and improving patient compliance by reducing dosing frequency. Logout 250mg Capsule SR should be administered orally, with dosage tailored according to patient response and serum uric acid levels. It is important to maintain adequate hydration during therapy to minimize the risk of renal complications. Common adverse effects include rash, gastrointestinal disturbances, and hypersensitivity reactions; severe hypersensitivity syndrome, although rare, requires immediate discontinuation of the drug. Regular monitoring of renal and hepatic function, as well as serum uric acid levels, is recommended during treatment. Logout 250mg Capsule SR is contraindicated in patients with known hypersensitivity to allopurinol and should be used cautiously in those with renal impairment.
