Pregnancy Category

Name : Not Classified

Description

FDA has not yet classified the drug into a specified pregnancy category.

Mode of Action

Allopurinol is an inhibitor of the enzyme xanthine oxidase which converts hypoxanthine to xanthine then uric acid. The reduced production of uric acid relieves all symptoms associated with hyperuricaemia and gout. Inhibition of xanthine oxidase leads to accumulation of its substrates hypoxanthine and xanthine but since their renal clearance is more than 10 times that of uric acid, there is no risk of nephrolithiasis.

Interaction

May inhibit the metabolism of mercaptopurine and azathioprine; reduce dose of mercaptopurine and azathioprine when given w/ allopurinol. May increase effect of warfarin and other coumarin anticoagulants. Increased excretion of the oxipurinol (metabolite) w/ salicylates or uricosuric agents. Increased toxicity w/ thiazide diuretics, some antibacterials, other antineoplastics, ciclosporin, some sulfonylurea antidiabetics, theophylline and vidarabine.

Pregnancy Category Note

Pregnancy Experience with human pregnancy limited partly because women of reproductive age rarely require treatment with drug; There are, however, no adequate or well controlled studies in pregnant women; because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed Lactation Allopurinol and oxipurinol have been found in milk of mother who was receiving drug; since effect of allopurinol on nursing infant is unknown, exercise caution when therapy is administered to nursing woman
