It is a drug used to treat hyperuricemia, gout, and urinary stones, and is chemically a stereoisomer of hypoxanthine. It competitively inhibits xanthine oxidase at low concentrations, and noncompetitively at high concentrations. As a result, blood and urinary uric acid levels drop significantly. It is taken orally at 0.2 to 0.3 grams per day. It is a highly toxic drug, and the maximum dose is 0.2 grams per dose, or 0.6 grams per day.
