From the Guidelines

The most effective approach for managing elevated diastolic blood pressure involves using a combination of medications from different classes, with a preference for single-pill combinations, as recommended by the 2024 ESC guidelines 1. When considering the best medication for elevated diastolic blood pressure, it's essential to look at the most recent and highest quality evidence. The 2024 ESC guidelines for the management of elevated blood pressure and hypertension provide a comprehensive approach to treating hypertension, emphasizing the importance of combination therapy 1.

Key Medication Classes

The major four drug classes recommended as first-line BP-lowering medications are:

  • ACE inhibitors
  • ARBs
  • Dihydropyridine CCBs
  • Thiazide or thiazide-like diuretics These can be used alone or in combination, with the exception of combining two RAS blockers, which is not recommended 1.

Treatment Approach

For most hypertensive patients, a single-pill combination containing two of the major drug classes, initially at low dose, is recommended 1. This approach allows for additive or synergistic effects, leading to greater BP reduction, and potentially fewer side effects due to the use of lower doses of each individual agent 1.

Lifestyle Modifications

In addition to medication, lifestyle modifications play a crucial role in managing hypertension, including:

  • Reducing sodium intake
  • Regular exercise
  • Limiting alcohol consumption
  • Maintaining a healthy weight
  • Following a DASH diet rich in fruits, vegetables, and low-fat dairy

Resistance and Further Treatment

If blood pressure remains uncontrolled under maximally tolerated triple-combination therapy, the patient should be considered resistant and referred to an expert center for appropriate work-up, with considerations for adding spironolactone or other medications as fourth-line treatment 1.

Conclusion on Best Medication

Given the current evidence, the best initial approach for elevated diastolic blood pressure involves starting with a low-dose combination of two medications from the recommended classes, preferably in a single-pill combination, and adjusting as necessary based on patient response and tolerance, as outlined in the 2024 ESC guidelines 1.

From the FDA Drug Label

In controlled clinical studies of patients with mild to moderate hypertension, patients were treated with lisinopril 20 mg to 80 mg daily, hydrochlorothiazide 12. 5 mg to 50 mg daily or atenolol 50 mg to 200 mg daily; and in other studies of patients with moderate to severe hypertension, patients were treated with lisinopril 20 mg to 80 mg daily or metoprolol 100 mg to 200 mg daily. Lisinopril demonstrated superior reductions of systolic and diastolic compared to hydrochlorothiazide in a population that was 75% Caucasian Lisinopril was approximately equivalent to atenolol and metoprolol in reducing diastolic blood pressure, and had somewhat greater effects on systolic blood pressure.

The best medication for elevated diastolic blood pressure (hypertension) cannot be determined from the provided information, as the FDA label does not explicitly state a single best medication. However, lisinopril has been shown to be effective in reducing diastolic blood pressure, and its effects are comparable to or superior to other medications such as hydrochlorothiazide, atenolol, and metoprolol in certain populations 2.

From the Research

Medication Options for Elevated Diastolic Blood Pressure

The following medications have been studied for their effectiveness in treating elevated diastolic blood pressure:

  • Angiotensin converting enzyme (ACE) inhibitors, such as lisinopril 3, 4
  • Calcium channel blockers, such as amlodipine 3, 5
  • Thiazide diuretics, such as chlortalidone and hydrochlorothiazide 6, 5
  • Angiotensin receptor blockers (ARBs), such as olmesartan 5

Combination Therapy

Combination therapy with two or more of these medications may be effective in achieving blood pressure goals:

  • The combination of amlodipine and lisinopril was found to have a significant additional blood pressure lowering effect compared to either medication alone 3
  • The combination of an ARB, a calcium channel blocker, and a thiazide diuretic may be a rational choice for triple fixed-dose combination therapy 5

First-Line Treatment

According to some studies, the first-line treatment for hypertension in nondiabetic adults without cardiovascular or renal disease should be a thiazide diuretic, such as chlortalidone or hydrochlorothiazide 6

  • If a thiazide diuretic cannot be used, an ACE inhibitor, such as lisinopril, may be a suitable alternative 6, 4
