Recommended Approach to Initiating and Adjusting Medication for Hypertension
The recommended approach for hypertension management is to start with a combination of two first-line agents for most patients with stage 2 hypertension (≥160/100 mmHg), while a single agent is appropriate for stage 1 hypertension (140-159/90-99 mmHg), with subsequent medication adjustments to achieve target blood pressure within 3 months. 1
Initial Medication Selection
For Stage 1 Hypertension (140-159/90-99 mmHg):
- Start with a single antihypertensive drug, preferably from one of the four major classes: ACE inhibitors, ARBs, thiazide/thiazide-like diuretics, or dihydropyridine calcium channel blockers 1
- For high-risk patients (with CVD, CKD, diabetes, organ damage, or aged 50-80 years), initiate drug treatment immediately along with lifestyle modifications 1
- For lower-risk patients, a 3-6 month trial of lifestyle modifications before starting medication is appropriate 1
For Stage 2 Hypertension (≥160/100 mmHg):
- Initiate treatment with two first-line agents of different classes, either as separate agents or in a fixed-dose combination 1
- Fixed-dose single-pill combinations are preferred to improve adherence 1
- Start drug treatment immediately along with lifestyle modifications 1
Population-Specific Initial Drug Selection
Non-Black Patients:
- Start with low-dose ACE inhibitor or ARB, typically combined with either a dihydropyridine CCB or thiazide/thiazide-like diuretic 1, 2
- Example: Lisinopril starting at 10 mg once daily, adjusting to 20-40 mg daily based on blood pressure response 3
Black Patients:
- Start with a dihydropyridine calcium channel blocker or thiazide/thiazide-like diuretic 1, 2
- For patients with albuminuria, an ARB is preferred 1
Patients with Diabetes:
- For patients with albuminuria (urine albumin-to-creatinine ratio ≥30 mg/g), an ACE inhibitor or ARB is recommended as first-line therapy 1
- For patients with established coronary artery disease, ACE inhibitors or ARBs are recommended first-line 1
Medication Adjustment Strategy
Titration Approach:
- Follow a stepped-care approach with sequential titration of dose and addition of other agents 2
- Add a second medication from a different class before reaching maximum dose of the first drug 2
- Aim to achieve blood pressure control within 3 months to maintain patient confidence and ensure long-term adherence 1
When Blood Pressure Is Not at Goal:
Two-Drug Combination Not Effective:
Three-Drug Combination Not Effective:
Monitoring and Follow-up
- Monitor serum creatinine/estimated glomerular filtration rate and serum potassium levels at least annually for patients treated with ACE inhibitors, ARBs, or diuretics 1
- Assess blood pressure control every 2-4 weeks during the titration phase until target is reached 2
- Once target is achieved, follow-up can be less frequent (e.g., every 3-6 months) 1
Important Cautions and Contraindications
- Avoid combining two RAS blockers (ACE inhibitor and ARB) due to increased risk of adverse events without additional benefit 1, 2
- Use caution when initiating therapy with two drugs in older patients due to risk of hypotension or orthostatic hypotension 1
- For patients aged ≥85 years, those with symptomatic orthostatic hypotension, or moderate-to-severe frailty, consider starting with monotherapy and slower titration 1
- For patients on hemodialysis or with creatinine clearance <10 mL/min, reduce initial doses (e.g., lisinopril 2.5 mg once daily) 3
