From the Guidelines
For a 62-year-old patient with hypertension on amlodipine, chlorthalidone, and olmesartan who still has elevated blood pressure, I recommend optimizing the current medication doses before adding a fourth agent, as suggested by the 2024 ESC guidelines for the management of elevated blood pressure and hypertension 1. The patient's current regimen includes a dihydropyridine calcium channel blocker (amlodipine), a diuretic (chlorthalidone), and an angiotensin receptor blocker (olmesartan), which are all recommended as first-line treatments for hypertension 1. To optimize the current medication doses, I suggest:
- Increasing amlodipine to 10mg daily if not already at this dose
- Increasing chlorthalidone to 25mg daily if not already at this dose
- Increasing olmesartan to 40mg daily if not already at this dose Medication adherence should be verified, as non-adherence is a common cause of treatment failure. If blood pressure remains uncontrolled despite optimized doses, adding spironolactone 25mg daily would be appropriate as a fourth-line agent, particularly effective in resistant hypertension, as recommended by the 2024 ESC guidelines 1. Additionally, lifestyle modifications should be reinforced, including:
- Sodium restriction to less than 2g daily
- Regular physical activity
- Weight management
- Limited alcohol consumption
- The DASH diet These non-pharmacological approaches can significantly impact blood pressure control, as suggested by the American College of Physicians and the American Academy of Family Physicians 1 and the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure 1. The patient should also be evaluated for secondary causes of hypertension, such as sleep apnea, primary aldosteronism, or renal artery stenosis, which may explain resistance to the current regimen. It is essential to note that the American Diabetes Association recommendations are not directly applicable to this patient, as the patient's diabetes status is not mentioned. However, the 2024 ESC guidelines provide a comprehensive approach to managing hypertension, which can be applied to this patient's case 1.

Adjustments for 62-Year-Old Patient with Hypertension
The American Diabetes Association recommends tight blood pressure control for patients with hypertension, especially those with diabetes or kidney disease. For a 62-year-old patient with elevated blood pressure (150/94 mmHg) on amlodipine, clorthalidine, and olmesartan, the following adjustments are recommended:
- Uptitration of current medications: The patient is already on a combination of amlodipine, clorthalidine, and olmesartan, which is a recommended approach for patients with poor blood pressure control 2, 3.
- Addition of hydrochlorothiazide: Studies have shown that adding hydrochlorothiazide to the combination of olmesartan and amlodipine can provide additional blood pressure lowering effects 2, 3.
- Monitoring of blood pressure: Regular monitoring of blood pressure is essential to assess the effectiveness of the treatment and make adjustments as needed.
Considerations for Combination Therapy
The combination of olmesartan and amlodipine has been shown to be effective in reducing blood pressure and is well-tolerated in patients with hypertension 2, 3, 4. The addition of clorthalidine to this combination may provide additional blood pressure lowering effects, but its use should be monitored closely due to potential side effects.
Special Considerations for Older Adults
Older adults, such as the 62-year-old patient in question, may require special consideration when it comes to blood pressure management. Studies have shown that the combination of olmesartan and amlodipine is effective and well-tolerated in older adults 5. However, careful monitoring of blood pressure and potential side effects is essential to ensure safe and effective treatment.
Blood Pressure Targets
The American Diabetes Association recommends a blood pressure target of less than 140/90 mmHg for most adults, and less than 130/80 mmHg for those with diabetes or kidney disease. For the 62-year-old patient in question, a blood pressure target of less than 140/90 mmHg may be appropriate, but this should be individualized based on the patient's specific needs and health status 2, 3.
