Abstract
  1. The plasma levels and the urinary excretion of hydrochlorothiazide (HCT) have been studied after administration of single doses of 12.5 and 25 mg of the drug in solution and in combination with 100 mg of the selective beta 1-adrenoreceptor antagonist metoprolol in a rapidly dissolving tablet. 2. Metoprolol did not significantly influence the bioavailability or the time-course of HCT. 3. HCT had no significant effect on the time-course or the plasma levels of metoprolol. The average half-life, 4.4 +/- 0.9 h, is about the same as previously observed for separate doses of this drug. 4. It seems unlikely that repeated doses of the combination product studied will lead to biopharmaceutic or pharmacokinetic interactions of clinical importance.
摘要
  1. 研究了单次服用12.5毫克和25毫克氢氯噻嗪(HCT)溶液剂以及与100毫克选择性β1肾上腺素能受体拮抗剂美托洛尔制成的速溶片后,HCT的血浆水平和尿排泄情况。2. 美托洛尔对HCT的生物利用度或时程没有显著影响。3. HCT对美托洛尔的时程或血浆水平没有显著影响。平均半衰期为4.4±0.9小时,与先前单独服用该药物时观察到的情况大致相同。4. 所研究的复方制剂重复给药似乎不太可能导致具有临床重要性的生物药剂学或药代动力学相互作用。
