Oxametacin, a new non steroidal anti-inflammatory compound, with analgesic, antipyretic and anti-inflammatory properties comparable to those of indomethacin, has been claimed to be effective in treatment of acute attacks of gout. The present study comprises an investigation in 8 healthy volunteers of the effect on the endogenous uric acid clearance rate, of oxametacin administered alone or in combination with the conventional hypouricaemic agents benzbromarone or allopurinol. Whether given alone or in combination with these drugs, oxametacin failed to alter the clearance rate of endogenous uric acid. In view of its good tolerance and its possible efficacy in treatment of acute attacks of gout, the present data help to validate use of oxametacin in acute gout. 相似文献

Iridoid glycosides of Paederia scandens (IGPS) are an active component isolated from Chinese herb P. scandens (LOUR.) MERRILL (Rubiaceae). Uric acid nephropathy (UAN) is caused by excessive uric acid, which results in damage of kidney tissue via urate crystals deposition in the kidneys. This study aimed to investigate the protective effects of IGPS on UAN in rats induced by yeast and potassium oxonate. Treatment groups received different doses of IGPS and allopurinol (AP) daily for 35 days respectively. The results showed that treatment with IGPS significantly prevented the increases of uric acid in serum and the elevation of systolic blood pressure (SBP), attenuated renal tissue injury, improved renal function and reserved the biological activity of NOS-1. IGPS also inhibited the biological activity of TNF-α and TGF-β1, and suppressed the mRNA expressions of TNF-α and TGF-β1 in renal tissue. Taken together, the present and our previous findings suggest that IGPS exerts protective effects against kidney damage in UAN rats through its uric acid-lowering, anti-inflammatory and immunomodulatory properties. Furthermore, decreasing SBP by up regulation of NOS-1 expression and down regulation of TNF-α and TGF-β1 expression are involved in the effect of IGPS on high uric acid-induced nephropathy. 相似文献

Azapropazone is an anti-inflammatory agent with reported uricosuric properties. The aim of the present study was to extend these observations, by examining the dose-response and to compare the uricosuric effect of azapropazone with that of probenecid. Patients were given varying doses of azapropazone from 900-2400 mg daily for 4-day periods at separated intervals. Plasma uric acid levels were measured before and at the end of each treatment period. Three other patients maintained on low purine diets were given a 4-day course of 1200 mg azapropazone daily followed at an interval by a 4-day period of probenecid 1 g daily. Plasma uric acid levels and 24 h urinary uric acid excretion were compared. The mean fall in plasma uric acid level after four days of 900 mg azapropazone daily was 31.4% (n = 9) compared with 33.9% (n = 12) on 1200 mg daily; 42.3% (n = 10) on 1800 mg daily; and 46% (n = 6) on 2400 mg daily, indicating a graded dosage response. In the three patients on low purine diets the falls in plasma uric acid levels on probenecid 1 g daily were 50.5%, 46% and 29% compared with 33.5%, 32% and 20% respectively on azapropazone 1200 mg daily. Similarly the total amount of uric acid excreted in the urine by each patient during the 4-day period on probenecid 1 g daily was 14.01; 13.03 and 8.97 mmol compared with 23.53, 10.9 and 7.69 mmol on azapropazone 1200 mg daily.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献
