Measure
Amlodipine Then Eplerenone
The subject will be started on Amlodipine 2.5-10 mg daily, which he or she will continue for a period of 8 weeks. After completion of the study procedures, the medication will be discontinued. The subject will be started on Eplerenone 50 - 200 mg daily, which he or she will continue for a period of 8 weeks.
Eplerenone Then Amlodipine
The subject will be started on Eplerenone 50 - 200 mg daily, which he or she will continue for a period of 8 weeks. After completion of the study procedures, the medication will be discontinued. The subject will be started on Amlodipine 2.5-10 mg daily, which he or she will continue for a period of 8 weeks.
