Primary Outcome Measures:
  • Area Under the Concentration-time Curve of Plasma Amlodipine From 0 to 72 Hours (AUC72) [ Time Frame: Day 1, Day 22 ]
    Area under the analyte concentration versus time curve from time zero to 72 hours as calculated by the linear trapezoidal method

  • Maximum Observed Plasma Concentration (Cmax) of Amlodipine [ Time Frame: Day 1, Day 22 ]

Secondary Outcome Measures:
  • Time of Maximum Concentration of Amlodipine (TMAX) [ Time Frame: Day 1, Day 22 ]
    Time of maximum measured amlodipine concentration over the zero to 72 hour sampling period

Enrollment: 28
