Antihypertensive Medication Dosing Strategy

Initial Approach to Antihypertensive Therapy

The American College of Cardiology recommends a stepped-care approach defined as initiation of antihypertensive drug therapy with a single agent followed by sequential titration of the dose and addition of other agents before reaching maximum dose of the first drug 1, 2
The National High Blood Pressure Education Program has recommended this approach since its first report in 2003 3
For patients with stage 1 hypertension, initiation with a single antihypertensive drug is reasonable 2

The JNC 8 guidelines suggest starting one drug, then adding a second drug before achieving maximal dose of the first drug as one of their recommended dosing strategies 4
Most adults with hypertension will require more than one drug to achieve BP control, with approximately 75% needing multiple medications 1, 2
Adding a second medication from a different class is recommended when a single agent at initial doses fails to achieve the BP goal 3

Option A is not the preferred strategy according to current guidelines from the American College of Cardiology and Hypertension 1, 2, 4
Option C is not supported by guidelines, which recommend lifestyle modifications first for elevated BP from the American Heart Association and Hypertension 2, 5

For patients with stage 2 hypertension or BP more than 20/10 mmHg above target, initiation with two first-line agents of different classes is recommended by the American College of Cardiology and Hypertension 1, 2

Initial drug selections should be based on trial evidence of treatment efficacy, compelling indications, and patient characteristics from Hypertension 2
For most non-black patients, initial therapy often includes an ACE inhibitor or ARB from Hypertension 5, 6
For black patients, initial therapy often includes a calcium channel blocker or thiazide diuretic from Hypertension 5, 6

Blood pressure should be monitored and medications adjusted every 2-4 weeks until BP is controlled from Drugs 4
The goal is to achieve BP control within 3 months from Hypertension 5, 6
Regular monitoring of renal function and electrolytes is recommended when using ACE inhibitors, ARBs, or diuretics from Diabetes Care 7

Dual RAAS blockade should be avoided due to increased risk of adverse events from Drugs 4
Waiting too long to add a second agent can delay achievement of BP control from the American College of Cardiology and Hypertension 1, 2
