Effect of Pyridoxal on Pyrazinamide - and its metabolite-induced Hyperuricemia

Pyrazinamide와 그 대사산물이 유발하는 고뇨산 혈증에 미치는 Pyridoxal의 영향

Pyrazinamide, an amide of pyrazinoic acid, is widely used in combination with other drugs for the treatment of tuberculosis. It was attempted to observe the effect of pyridoxal on the pyrazinamide induce hyperuricemia in this study. It was observed that the values of serum transminases were not changed in mice injected pyrazinamide and pyrazinoic acid, respectively (100, 200, and 300mg/kg) compared with control. Blood urate levels were increased in mice treated with these drugs in a dose dependent manner. After pyrazinoic acid was administered intraperitoneally at a dose of 300mg/kg pretreated with 50mg/kg of pyridoxal once daily for 4 days, the blood levels of uric acid and pyrazinoic acid were decreased significantly.
