 (submitted: January 10, 2013)
Tolerability [ Time Frame: Participants will be followed for the duration of study, an expected average of 6 weeks. ]
Tolerability was assessed based on changes in vital signs (temperature, blood pressure, pulse, and heart rate), measured before dosing in each period and approximately every 4 hours thereafter, and laboratory tests (hematology, biochemistry, liver function, and urinalysis), and performed at baseline and at the end of the study. In addition, a physician questioned volunteers about any adverse events occurring during the study, addressed them as necessary, and recorded them on the appropriate form. This physician was not blinded to treatment, but had no involvement in the study.

Brief Title  ICMJE Pharmacokinetic Interactions of Valsartan and Hydrochlorothiazide (Double Doses)
Official Title  ICMJE Pharmacokinetic Interactions of Valsartan and Hydrochlorothiazide: An Open-Label, Randomized, Four-Period Crossover Study in Healthy Egyptian Male Volunteers (PART II)
Brief Summary This study was conducted to compare the rate and extent of absorption of valsartan and hydrochlorothiazide. To maximize the possibility of finding drug-drug interactions, the dose of valsartan and hydrochlorothiazide was doubled (320 mg of VAL and 25 mg of HCT).
