The present study aimed to determine the effect of Hibiscus sabdariffa and Zingiber officinale on antihypertensive activity and pharmacokinetic of losartan in hypertensive rats.Hypertension was induced in rats by oral administration of L-NAME (40 mg/kg per day). Pharmacodynamics and pharmacokinetics of losartan were evaluated without and with herbal treatment in hypertensive rats.Treatment of hypertensive rats with investigated herbs substantially reduced systolic blood pressure (SBP), and diastolic blood pressure (DBP) of rats. Treatment of rats (n = 5) with L-NAME plus H. sabdariffa plus losartan and L-NAME plus Z. officinale plus losartan reduced SBP by 16.20% and 14.88% and DBP by 14.82% and 17.52% respectively after 12 h, as compared to L-NAME alone treated rats. In a pharmacokinetic study, the Cmax and AUC0-t of losartan in L-NAME plus H. sabdariffa plus losartan and L-NAME plus Z. officinale plus losartan treated rats was increased by 0.7, 1.99 and 1.51, 3.00 fold respectively in comparison to the Cmax and AUC0-t obtained for L-NAME plus losartan treated group. In conclusion, both the investigated herbs significantly increased the antihypertensive effect and plasma concentration of losartan in L-NAME induced hypertensive rats. The current study predicted that the herb-drug interaction between H. sabdariffa-losartan and Z. officinale-losartan could occur; hence these results in rats may warrant further studies in humans, either in humans or in in vitro human liver microsomes.

芙蓉和生姜对高血压大鼠氯沙坦的降压活性和药代动力学的影响。

本研究旨在确定芙蓉和生姜对氯沙坦在高血压大鼠中的抗高血压活性和药代动力学的影响,通过口服L-NAME(40 mg / kg /天)诱导高血压。评估氯沙坦在不使用和使用草药的情况下在高血压大鼠中的药效学和药代动力学。用研究草药治疗高血压大鼠可显着降低大鼠的收缩压(SBP)和舒张压(DBP)。在12小时后,使用L-NAME加H. sabdariffa加氯沙坦和L-NAME加Z. officinale加氯沙坦治疗大鼠(n = 5)分别使SBP降低16.20%和14.48%,DBP分别降低14.82%和17.52%。与单独使用L-NAME治疗的大鼠相比。在药代动力学研究中,氯沙坦在L-NAME和H中的Cmax和AUC0-t。与L-NAME加氯沙坦治疗组的Cmax和AUC0-t相比,sabdariffa加氯沙坦和L-NAME加Z.officinale加氯沙坦治疗的大鼠分别增加了0.7、1.99和1.51、3.00倍。综上所述,两种所研究的草药均显着提高了氯沙坦在L-NAME诱导的高血压大鼠中的抗高血压作用和血浆浓度。目前的研究预测,沙巴达菲-氯沙坦和奥沙利坦-氯沙坦之间可能发生草药-药物相互作用。因此,在大鼠中的这些结果可能需要在人体中或在体外或人体外肝微粒体中进行进一步研究。与L-NAME加氯沙坦治疗组的Cmax和AUC0-t相比,分别为00倍。综上所述,两种所研究的草药均显着提高了氯沙坦在L-NAME诱导的高血压大鼠中的抗高血压作用和血浆浓度。目前的研究预测,沙巴达菲-氯沙坦和奥沙利坦-氯沙坦之间可能发生草药-药物相互作用。因此,在大鼠中的这些结果可能需要在人体中或在体外或人体外肝微粒体中进行进一步研究。与L-NAME加氯沙坦治疗组的Cmax和AUC0-t相比,分别为00倍。综上所述,两种所研究的草药均显着提高了氯沙坦在L-NAME诱导的高血压大鼠中的抗高血压作用和血浆浓度。目前的研究预测,沙巴达菲-氯沙坦和奥沙利坦-氯沙坦之间可能发生草药-药物相互作用。因此,在大鼠中的这些结果可能需要在人体中或在体外或人体外肝微粒体中进行进一步研究。
