Hypertension Management with Perindopril and Second Agent
Rationale for Combination Therapy
- Most hypertensive patients require more than one drug to achieve blood pressure control, with combination therapy being necessary for the majority of patients 3
- When adding a second agent to an ACE inhibitor like perindopril, the most effective and complementary combinations include a calcium channel blocker or a thiazide diuretic 3, 1
- The British Hypertension Society recommends combining drugs with complementary mechanisms of action - specifically an ACE inhibitor with either a calcium channel blocker or a diuretic 2
Preferred Second Agent: Calcium Channel Blocker
- A calcium channel blocker is the preferred second agent to add to perindopril based on the most recent European Society of Cardiology guidelines 1, 4
- The American College of Cardiology and European Society of Cardiology recommend a calcium channel blocker, particularly amlodipine, as the preferred second agent to add to perindopril 1, 4
Alternative Second Agent: Thiazide Diuretic
- If a calcium channel blocker is not tolerated or contraindicated, a thiazide diuretic is an effective alternative second agent 3, 5
- The European Society of Cardiology and American Heart Association suggest that perindopril combined with a thiazide diuretic has shown synergistic effects in blood pressure reduction 3
Special Populations and Considerations
- In black patients, initial combination therapy should include a calcium channel blocker with either a thiazide diuretic or a RAS blocker 1, 4
- For patients with resistant hypertension, adding spironolactone as a fourth agent should be considered if blood pressure remains uncontrolled on a three-drug regimen 1, 6
Common Pitfalls to Avoid
- Avoid combining two RAS blockers, as this increases adverse effects without additional benefit, according to the European Society of Cardiology 7
- Be cautious when combining beta-blockers with diuretics in patients at high risk for diabetes, as recommended by the British Hypertension Society 2
- Monitor for orthostatic hypotension when using multiple antihypertensive agents, especially in elderly patients, as advised by the British Journal of Cancer and European Society of Cardiology 6, 7
