Measure
KMgCit + Chlorthalidone
After a run-in period of 2-3 weeks on Chlorthalidone, patients will be randomized to the addition of KMgCit for 4 months. Potassium Magnesium Citrate (KMgCit): KMgCit will be administer for 4 months with chlorthalidone. Chlorthalidone: Chlorthalidone will be administered for 2-3 weeks. Then either KCL or KMgCit will be added to Chlorthalidone and the combination will be taken for 4 months.
KCl + Chlorthalidone
After a run-in period of 2-3 weeks on Chlorthalidone, patients will be randomized to the addition of KCl for 4 months. Potassium Chloride (KCl): KCl will be administer for 4 months with chlorthalidone. Chlorthalidone: Chlorthalidone will be administered for 2-3 weeks. Then either KCL or KMgCit will be added to Chlorthalidone and the combination will be taken for 4 months.
