Further study details as provided by King Pharmaceuticals Research and Development:

Primary Outcome Measures:

Compare the effects on sitting diastolic blood pressure of two antihypertensive drugs in combination against each antihypertensive alone after an eight week treatment period.

Secondary Outcome Measures:

Compare the effect on sitting diastolic blood pressure of two antihypertensive drugs in combination taken once daily against one antihypertensive drug taken twice daily.
Compare the effect on sitting diastolic blood pressure of a dose of an antihypertensive drug taken once daily against half of the same dose taken twice daily.
Compare the effect on the sitting and standing blood pressure among all treatment groups.
Compare the safety of each medication regimen stated above.
Compare the effect on mean 24-hour diastolic blood pressure (ABPM) of the medication regimens stated above.
