Patients with diabetes and without CKD (all ages) 50% achieved the JNC-8 goal (less than140/90 mmHg) and Patients with CKD or without DM (all ages and races) 60% achieved the JNC-8 goal (less than140/90 mmHg). Conclusion: Calcium channel blockers (Amlodipine) and diuretics (Furosemide) were the drug of choice for hypertensive patients as a single drug and combination drug therapy.
