Pyrazone : Each tablet contains Sulfinpyrazone BP 200 mg.
Pyrazone helps to remove excess uric acid from the body. Too much uric acid can cause gout or gouty arthritis. Certain illness or medications can increase uric acid level. It can help to reduce the risk of complications (such as kidney stones) that can occur if uric acid levels in the blood are too high (hyperuricemia).It completely inhibits the reabsorption of uric acid at the proximal convoluted tubule, thereby facilitating urinary excretion of uric acid and decreasing plasma urate concentrations.
Pyrazone is indicated for the treatment of:
Chronic gouty arthritis
Intermittent gouty arthritis
Dosage & Administration
200-400 mg daily in two divided doses, with meals or milk, gradually increasing when necessary to full maintenance dosage in one week.
The symptoms are upset stomach, vomiting, loss of appetite and joint pain. If you experience any of the following symptoms like difficulty in breathing, tightness in the chest, skin rash, unusual bleeding, fever, sore throat and mouth sores, call your doctor immediately.
Patients receiving Pyrazone should be kept under close medical supervision and periodic blood counts are recommended. It may be administered with care to patients with a history of healed peptic ulcer. It is suggested that Pyrazone should be used with caution in conjunction with sulfa drugs, the sulfonylurea hypoglycemic agents and insulin. Because Pyrazone is a potent uricosuric agent, it may precipitate urolithiasis and renal colic, especially in the initial stages of therapy. For this reason, an adequate fluid intake and alkalinization of the urine are recommended. Salicylates antagonize the uricosuric action of Pyrazone and for this reason, their concomitant uses are contraindicated in gouty arthritis.
Patients with an active peptic or symptoms of gastro-intestinal inflammation or ulceration should not receive the drug. The drug is contraindicated in patients with a history or the presence of hypersensitivity to phenylbutazone or other pyrazoles.
