First-line low-dose thiazides reduce all morbidity and mortality outcomes .
First-line ACE inhibitors and calcium channel blockers may be similarly effective but the evidence is less robust .
First-line high-dose thiazides and first-line beta-blockers are inferior to first-line low-dose thiazides
BACKGROUND Sustained elevated blood pressure , unresponsive to lifestyle measures , leads to a critically important clinical question : What class of drug to use first-line ?
This review answers that question .
OBJECTIVES PRIMARY OBJECTIVE To quantify the benefits and harms of the major first-line anti-hypertensive drug classes : thiazides , beta-blockers , calcium channel blockers , angiotensin converting enzyme ( ACE ) inhibitors , alpha-blockers , and angiotensin II receptor blockers ( ARB ) .
Primary prevention with metoprolol in patients with hypertension. Mortality results from the MAPHY study.
The present study of primary prevention in white men aged 40 to 64 years attempts to investigate whether a beta-blocker given as initial antihypertensive treatment would lower total mortality to a greater extent than thiazide diuretics .  Patients were r and omized to metoprolol ( n = 1609 , 8110 patient-years ) or a thiazide diuretic ( n = 1625 , 8070 patient-years ) . The median follow-up time was 4.2 years . The mean dose of metoprolol was 174 mg/d , and of thiazide diuretics , 46 mg/d of hydrochlorothiazide or 4.4 mg/d of bendroflumethiazide . Identical control of blood pressure was achieved using a fixed therapeutic schedule . Total mortality was significantly lower for metoprolol than for thiazide diuretics because of fewer deaths from coronary heart disease and stroke . Total mortality was also significantly lower in smokers r and omized to metoprolol .  The benefit demonstrated in patients treated with metoprolol seems to have important implication s for clinical practice
