From the Guidelines
The next step in managing a patient with a history of allergy to Altace (Ramipril) and uncontrolled hypertension despite current therapy with Lopressor (Metoprolol), Norvasc (Amlodipine), and HCTZ (Hydrochlorothiazide) would be to add low-dose spironolactone to existing treatment, as recommended by the 2024 ESC guidelines for the management of elevated blood pressure and hypertension 1.
When considering the management of resistant hypertension, it's crucial to reinforce lifestyle measures, especially sodium restriction, and optimize the current treatment regimen. The addition of spironolactone is recommended for patients with resistant hypertension and uncontrolled BP despite the use of first-line BP-lowering therapies 1.
Key considerations for adding spironolactone include:
- Serum potassium levels should be <4.5 mmol/L
- eGFR should be >45 ml/min/1.73m2
- The patient should be monitored for potential side effects and interactions with other medications
Alternatively, if spironolactone is contraindicated or not tolerated, other options such as eplerenone, amiloride, doxazosin, or beta-blockers can be considered 1. However, the most recent and highest quality study, the 2024 ESC guidelines, prioritizes the addition of low-dose spironolactone as the next step in managing resistant hypertension 1.
It's also essential to verify medication adherence, proper blood pressure measurement technique, and rule out secondary causes of hypertension before adding more medications. Lifestyle modifications, including sodium restriction, weight loss if applicable, regular exercise, and limiting alcohol, should be reinforced as these can significantly impact blood pressure control.
In cases where blood pressure remains uncontrolled despite optimal medical therapy, catheter-based renal denervation may be considered for resistant hypertension patients who have BP that is uncontrolled despite a three BP-lowering drug combination, and who express a preference to undergo renal denervation after a shared risk-benefit discussion and multidisciplinary assessment 1.
From the Research
Patient Assessment
The patient has a history of allergy to Altace (Ramipril) and uncontrolled hypertension despite current therapy with Lopressor (Metoprolol), Norvasc (Amlodipine), and HCTZ (Hydrochlorothiazide). To manage this patient, the following steps can be considered:
- Assess adherence to current antihypertensive medication regimen and exclude pseudoresistance 2
- Exclude secondary causes of hypertension, such as aldosterone excess, and consider screening for these causes if clinically indicated 2, 3
- Optimize the antihypertensive regimen by ensuring medications are prescribed at optimal doses and using drugs with complementary mechanisms of action 2, 3
Treatment Options
Considering the patient's allergy to Altace (Ramipril), an ACE inhibitor, and current therapy with Lopressor (Metoprolol), Norvasc (Amlodipine), and HCTZ (Hydrochlorothiazide), the following treatment options can be considered:
- Addition of a mineralocorticoid receptor antagonist, such as spironolactone, as a fourth-line treatment for resistant hypertension 4, 3
- Alternative options, such as amiloride, doxazosin, eplerenone, clonidine, and beta-blockers, can be considered if spironolactone is not tolerated or effective 3
- Combination therapy with a long-acting thiazide-like diuretic and an MR antagonist can be effective in patients with refractory hypertension 4
Lifestyle Modifications
Healthy lifestyle habits are associated with reduced cardiovascular risk in patients with resistant hypertension, and the following modifications can be recommended:
