“…However, in some cases the uricosuric effect is inadequate in the smaller doses, while larger doses may not be well tolerated, and in such circumstances the patient may experience little or no improvement. Phenylbutazone has been shown to have a good uricosuric effect when administered in doses of 0-6 to 1 g. daily (YU and others, 1953;Bishop and Beecher, 1953;Wyngaarden, 1955), and is also very effective in controlling the acute attacks of gouty arthritis (Kuzell, Schaffarzick, Naugler, Koets, Mankle, Brown, and Champlin, 1955;Wilson, Huffman, and Smyth, 1956). However, its salt retaining properties (Yu and others, 1953;Brodie, Lowman, Bums, and five others, 1954a) and reported toxicity (Kuzell, Schaffarzick, Naugler, Gaudin, Mankle, and Brown, 1954;Kuzell and others, 1955;Mauer, 1955) are a distinct disadvantage and have discouraged to a large extent its use for the treatment of chronic gout (Yu and others, 1953).…”
