The herbal remedy Shu-Jing-Hwo-Shiee-Tang (SJHST) has been used in traditional Chinese medical care for the treatment of osteoarthritis. This study aims to examine the influence of SJHST on the oxidation and anticoagulation effect of warfarin in male rats. In three SJHST preparations (S1-S3), hesperidin, gentiopicrin, and paeoniflorin were identified as chemical marker ingredients. The inhibition of liver microsomal warfarin 7-hydroxylation (WOH) activity by 50% methanolic extracts of SJHST was potentiated by beta-glucosidase pretreatment, but not by NADPH-fortified microsomal preincubation. Among various ingredients and their b- glucosidase-hydrolyzed products, hesperetin caused the most potent inhibition of WOH. Oral administration of S2 to rats at 2 h after warfarin treatment (WS2(2)-h post), but not co-treatment (WS2co), decreased warfarin clearance and increased the maximal plasma concentration and the area under the curve (AUC(0- t), AUC(0-infinity)) of plasma concentration versus time of warfarin administration. S2 and S3 did not change the coagulation parameters. At 24 h after warfarin administration, the WS2(2-h) post and WS3(2-h) post groups had a prothrombin time longer than that of the warfarin group.These results demonstrate that a 2-h post-treatment of rats with SJHST caused pharmacokinetic interaction with warfarin, resulting in prothrombin time prolongation.
