From the Guidelines
For a patient with diabetes, obesity, and angina, an ACE inhibitor (such as lisinopril 10-40 mg daily) or an angiotensin receptor blocker (ARB) like losartan 25-100 mg daily would be the best initial hypertension medication. These medications are particularly beneficial because they provide kidney protection for diabetic patients, can improve insulin sensitivity, and don't negatively impact metabolic parameters that could worsen obesity. Additionally, they reduce cardiac workload and can help manage angina symptoms. A beta-blocker (such as metoprolol 25-200 mg daily) might be added as a second agent since it specifically benefits patients with angina by reducing heart rate and myocardial oxygen demand. Calcium channel blockers (like amlodipine 5-10 mg daily) could also be considered as they're effective for both hypertension and angina. It's essential to avoid thiazide diuretics at higher doses as they may worsen glucose control and contribute to metabolic issues. Blood pressure should be targeted to below 130/80 mmHg for this patient population, with regular monitoring of kidney function, potassium levels, and glucose control, as recommended by the most recent guidelines 1.
Key considerations in managing hypertension in patients with diabetes include:
- Using medications that have been demonstrated to reduce cardiovascular events in patients with diabetes, such as ACE inhibitors, ARBs, thiazide-like diuretics, or dihydropyridine calcium channel blockers 1.
- Avoiding combinations of ACE inhibitors and angiotensin receptor blockers, as well as combinations of ACE inhibitors or angiotensin receptor blockers with direct renin inhibitors 1.
- Monitoring serum creatinine/estimated glomerular filtration rate and serum potassium levels at least annually in patients treated with an ACE inhibitor, angiotensin receptor blocker, or diuretic 1.
- Considering the addition of a beta-blocker for patients with angina, as it can help reduce heart rate and myocardial oxygen demand, thereby alleviating angina symptoms 1.
The most recent and highest quality study, published in 2024 1, supports the use of ACE inhibitors or ARBs as first-line therapy for hypertension in patients with diabetes and established coronary artery disease, emphasizing their role in reducing the risk of progressive kidney disease and cardiovascular events.

1 INDICATIONS & USAGE
- 1 Hypertension Amlodipine besylate tablets is indicated for the treatment of hypertension, to lower blood pressure. ... Some antihypertensive drugs have smaller blood pressure effects (as monotherapy) in black patients, and many antihypertensive drugs have additional approved indications and effects (e.g., on angina, heart failure, or diabetic kidney disease). These considerations may guide selection of therapy. Amlodipine besylate tablets may be used alone or in combination with other antihypertensive agents.
1. 2 Coronary Artery Disease (CAD)
Chronic Stable Angina Amlodipine besylate tablets is indicated for the symptomatic treatment of chronic stable angina. Amlodipine besylate tablets may be used alone or in combination with other antianginal agents
The most suitable antihypertensive medication for a patient with diabetes mellitus (DM), obesity, and angina pectoris is amlodipine, as it is indicated for the treatment of hypertension and chronic stable angina.
- Amlodipine can be used alone or in combination with other antihypertensive agents.
- The drug has been shown to reduce the risk of hospitalization for angina and to reduce the risk of a coronary revascularization procedure in patients with coronary artery disease (CAD) 2.
- However, it is essential to consider the patient's individual characteristics, such as diabetes management and lipid control, when selecting therapy 2.
From the Research
Patient Profile
- Diabetes mellitus (DM)
- Obesity
- Angina pectoris
Suitable Antihypertensive Medication
- According to 3, ACE inhibitors can be advantageous for prevention and halting progression of both micro- and macrovascular complications in patients with diabetes mellitus.
- However, 4 suggests that ACE inhibitors or diuretics should be considered as first-line antihypertensive drug therapy in obesity-hypertension.
- Considering the patient's angina pectoris, 5 and 6 suggest that calcium channel blocking agents (CCBs) may be preferred for managing angina pectoris.
- Additionally, 7 recommends renin-angiotensin system (RAS) blocker-based combination therapy, such as angiotensin II receptor blockers (ARBs) with a calcium channel blocker (CCB) or a diuretic, for patients with diabetic and non-diabetic renal impairment.
