Effect of Puerarin on the pharmacokinetics of glipizide in rabbits
摘要
Abstract
Objective To study the influence on the metabolism of Pu-erarin on the pharmacokinetics of glipizide capsule in healthy and diabetic rabbits.Methods Healthy New Zealand rabbits randomly assigned , one group was modeled , each group had 5 rabbits.Glipizide (5 mg) was taken orally once to every rabbit.After 2 weeks of clearing stage, Puerarin (18 mg· kg -1) was administered daily by auricular vein injection qd for 3 d, then glipizide was taken orally at the same dosage on the 4 d.The blood was drawn from ear vein before and after administe-ring glipizide in every rabbit.Then the blood concentration of glipizide was measured by HPLC.The pharmacokinetic parameter was calculated with pharmacokinetic software DAS 2.0.The pharmacokinetics of glipiz-ide in rabbits administered with or without Puerarin were analyzed by auto-control.Results The concentration time -curves were fit to the one-compartment model.In healthy group , administered with Puerarin , the t1/2 were (4.2 ±0.5),(3.58 ±0.7) h,ρmax were (15.5 ±0.8), (8.4 ±0.6 ) mg· L-1 , AUC0-35 were ( 134.8 ±0.7 ) , ( 77.2 ±1.4 ) mg· h· L -1; respectively before and after.In diabetic group , t1/2 were (7.6 ±0.9),(5.6 ±0.9) h,ρmax were (13.4 ±0.8),(10.6 ±0.9) mg· L-1,AUC0-35 were (10.5 ±0.8),(7.7 ±1.6) mg· h· L-1 respectively before and after.There were notable differences on t1/2 ,ρmax , AUC values of glipizide in rabbits administered with or without Puerarin ( P <0.05 ).Conclusion Puerarin shows significant impact on the pharmacokinetics of glipizide.关键词
