Low Dose Diuretics vs. Others From Psaty BM et al. JAMA 2003;289:2534
The Reasons Why Low-Dose Diuretics Should be Initial Therapy 1. They reduce cardiovascular morbidity and mortality. 2. They lower blood pressure, particularly in patients consuming excessive sodium. 3. They enhance the antihypertensive efficacy of all other antihypertensive drugs. 4. They rarely cause side effects. 5. They reduce calcium loss and osteoporosis. 6. They are relatively inexpensive.
If urine analysis found microalbumin, what would you recommend? Quantify level of proteinuria Prescribe a long-acting ACEI
If SBP remains above 140 mmHg, what next? Long-acting CCB

CONCLUSIONS 1. Get adequate out-of-office BP measurements. 2. Perform a limited but appropriate work-up. 3. Strongly encourage and monitor necessary lifestyle changes. 4. Initiate drug therapy if BP usually >140 or 90 regardless of age and >130 or 80 in diabetics, renal, or cardiac patients. 5. Start with a low-dose diuretic and sequentially add drugs appropriate to individual patient’s needs. 6. Use home BP measurements to guide therapy and avoid overtreatment. 7. Reach the goal of <140 or 90; if BP still >140 or 90 with adequate diuretic plus 2 more drugs, consider referral to a Hypertension Specialist.
