What is the next step for a patient with evening hypertension who is maximized on Losartan (losartan)?

From the Guidelines

For a patient with increased evening hypertension who is already on maximum-dose losartan, I recommend adding a low dose of spironolactone as the next line of treatment, provided the patient's serum potassium is <4.5 mmol/L and eGFR is >45 ml/min/1.73m2, as suggested by the 2020 international society of hypertension global hypertension practice guidelines 1. This approach is supported by recent reports documenting the efficacy of mineralocorticoid receptor blockade in improving blood pressure in patients with resistant hypertension, as seen in the 2018 American Heart Association scientific statement on resistant hypertension 1. The use of spironolactone as a fourth-line agent has been shown to be effective in achieving blood pressure targets, and its once-daily administration makes it a convenient option for patients. However, it is crucial to monitor serum potassium levels and adjust the dose accordingly to minimize the risk of hyperkalemia. If spironolactone is contraindicated or not tolerated, alternative options such as amiloride, doxazosin, eplerenone, clonidine, and beta-blockers can be considered, as recommended by the guidelines 1. Additionally, lifestyle modifications, including limiting evening salt intake, avoiding alcohol before bedtime, and maintaining consistent sleep patterns, should be reinforced to help manage nocturnal hypertension. Home blood pressure monitoring should be implemented to assess the effectiveness of the new regimen, with a goal of maintaining blood pressure below 130/80 mmHg throughout the 24-hour period. It is essential to note that the choice of the next line of treatment should be individualized based on the patient's specific needs and medical history, and that resistant hypertension should be managed in specialist centers with sufficient expertise and resources, as recommended by the guidelines 1. Key considerations in the management of resistant hypertension include optimizing the current treatment regimen, screening for secondary causes, and adding a fourth-line agent, such as spironolactone, to achieve blood pressure targets. By following these guidelines and individualizing treatment, healthcare providers can help improve blood pressure control and reduce the risk of cardiovascular complications in patients with resistant hypertension.

From the FDA Drug Label

The mean length of follow-up was 4.8 years. At the end of study or at the last visit before a primary endpoint, 77% of the group treated with losartan and 73% of the group treated with atenolol were still taking study medication Of the patients still taking study medication, the mean doses of losartan and atenolol were both about 80 mg/day, and 15% were taking atenolol or losartan as monotherapy, while 77% were also receiving hydrochlorothiazide (at a mean dose of 20 mg/day in each group)

The patient is already on losartan, and the next step for increased hypertension in the evening is not directly addressed in the provided drug label. However, considering the patient is already on losartan, possible next steps could include:

• Increasing the dose of losartan to the maximum recommended dose, if not already at that dose.
• Adding another antihypertensive agent, such as hydrochlorothiazide, to the treatment regimen, as was done in the LIFE study 2. It is essential to note that these are general considerations and not directly supported by the provided drug label for the specific scenario of increased hypertension in the evening.

From the Research

Next Steps for Patient with Increased Hypertension in the Evening

The patient is currently taking losartan, an angiotensin II receptor blocker, which is a common medication for treating hypertension 3.

• Assessing Current Treatment: The first step is to assess the patient's current treatment regimen and determine if the losartan dosage needs to be adjusted or if additional medications are required.
• Lifestyle Modifications: As recommended by 3, lifestyle modifications such as weight loss, healthy dietary pattern, physical activity, and limited alcohol consumption should be encouraged to help lower blood pressure.
• Adding a Diuretic: A study by 4 found that adding a low-dose diuretic to losartan was effective in reducing blood pressure, which may be a consideration for this patient.
• Evening Dosing: Research by 5 suggests that evening dosing of antihypertensive medications may be beneficial for patients with increased hypertension in the evening, but the evidence is not conclusive.
• Target Blood Pressure Levels: According to 3 and 6, the target blood pressure level should be less than 130/80 mmHg for most patients, but this may need to be individualized based on the patient's specific risk factors and medical history.

Considerations for Adjusting Treatment

When adjusting the patient's treatment regimen, the following factors should be considered:

• Medication efficacy: The effectiveness of the current medication regimen in controlling blood pressure.
• Side effects: The presence of any side effects or adverse reactions to the current medications.
• Patient compliance: The patient's ability to adhere to the prescribed treatment regimen.
• Cost and accessibility: The cost and accessibility of any new or additional medications.
