Antihypertensive drugs: selection by condition and age
Core first-line drug groups for uncomplicated adult hypertension
- ACE inhibitor: ramipril, enalapril, lisinopril
- ARB: losartan, telmisartan, valsartan
- Calcium-channel blocker (CCB): amlodipine, nifedipine
- Thiazide or thiazide-like diuretic: chlorthalidone, indapamide, hydrochlorothiazide
These reduce blood pressure mainly by lowering cardiac output and/or systemic vascular resistance. Lippincott Illustrated Reviews: Pharmacology, p. 289.
1. Drug choice by age
| Age / clinical situation | Usual preferred approach | Important precautions |
|---|---|---|
| Children and adolescents | ACE inhibitor, ARB, long-acting CCB, or thiazide, selected with a pediatric specialist | Look for secondary hypertension, especially renal disease. Dose by weight. |
| Adults <55 years | Often ACE inhibitor or ARB is suitable, especially if renin-angiotensin system blockade is indicated | Do not combine ACE inhibitor + ARB. Check creatinine and potassium after starting or increasing dose. |
| Adults ≥55 years | Long-acting dihydropyridine CCB such as amlodipine is commonly useful; thiazide-like diuretic is another option | CCBs can cause ankle edema; thiazides can cause low sodium, low potassium, gout. |
| Older adult, fit | Same major drug classes can be used, but start low and titrate gradually | Measure seated and standing BP, review interacting drugs, renal function, electrolytes, falls risk. |
| Age >80 years or frailty | Usually begin with one low-dose agent rather than immediate multi-drug therapy, then individualize | Avoid overtreatment, symptomatic hypotension, dizziness, falls, and acute kidney injury. ESC material suggests a systolic target around 130-140 mmHg if tolerated and monotherapy initially in very old/frail people. ESC older-adult guidance |
2. Drug choice according to associated condition
| Condition | Preferred drug(s) | Why / key notes |
|---|---|---|
| Diabetes with albuminuria or diabetic kidney disease | ACE inhibitor or ARB | Reduces intraglomerular pressure and slows kidney disease progression. For type 1 diabetes with hypertension and albuminuria, ACE inhibitors are preferred; in type 2 diabetes with microalbuminuria, ACE inhibitor or ARB is appropriate. Brenner and Rector’s The Kidney; Textbook of Family Medicine 9e. |
| Chronic kidney disease with albuminuria | ACE inhibitor or ARB | Kidney-protective when albuminuria is present. Monitor potassium and creatinine. Avoid ACE inhibitor plus ARB. |
| CKD without albuminuria | ACE inhibitor, ARB, CCB, or diuretic based on eGFR and volume status | Loop diuretic may replace thiazide when kidney function is markedly reduced or there is fluid overload. |
| Heart failure with reduced ejection fraction (HFrEF) | Evidence-based beta-blocker such as carvedilol, bisoprolol, or metoprolol succinate; ACE inhibitor/ARB or ARNI; mineralocorticoid antagonist and SGLT2 inhibitor when indicated | These are chosen primarily to improve heart-failure outcomes, with BP lowering as an added effect. Avoid verapamil and diltiazem in HFrEF. |
| Previous myocardial infarction / angina / coronary artery disease | Beta-blocker plus ACE inhibitor or ARB when indicated | Beta-blocker helps angina and post-MI cardiac protection. A cardioselective beta-blocker is commonly selected for angina with hypertension. |
| Atrial fibrillation or tachyarrhythmia | Beta-blocker or rate-limiting CCB, diltiazem/verapamil, if no HFrEF | Controls ventricular rate and lowers BP. Avoid non-dihydropyridine CCBs in HFrEF. |
| Prior stroke or TIA | Any effective BP-lowering regimen, often ACE inhibitor/ARB + thiazide-like diuretic | Long-term BP control reduces recurrent stroke risk. A 2025 systematic review supports antihypertensive treatment for secondary-stroke prevention (PMID: 39780283). |
| Isolated systolic hypertension in older adults | Long-acting CCB or thiazide-like diuretic | Common in older age. Titrate carefully and assess orthostatic BP. |
| Pregnancy, chronic hypertension | Labetalol, extended-release nifedipine, or methyldopa | Contraindicated: ACE inhibitors, ARBs, and direct renin inhibitors. Labetalol or methyldopa are traditional choices; nifedipine is widely used. |
| Severe hypertension in pregnancy | IV labetalol, IV hydralazine, or oral immediate-release nifedipine in monitored care | Requires urgent obstetric assessment for pre-eclampsia and maternal-fetal risk. |
| Asthma or significant COPD | Prefer ACE inhibitor, ARB, CCB, or diuretic when possible | Avoid nonselective beta-blockers. A cardioselective beta-blocker may sometimes be used if there is a strong cardiac indication. |
| Gout / hyperuricemia | Losartan or CCB may be useful | Avoid or minimize thiazide and loop diuretics if they worsen uric acid or provoke gout. |
| Benign prostatic hyperplasia | Alpha-1 blocker such as doxazosin can improve urinary symptoms, but is not routine first-line BP monotherapy | Risk of postural hypotension, especially in older people. |
| Migraine with hypertension | Beta-blocker, such as propranolol or metoprolol, when otherwise appropriate | May help migraine prevention. Avoid if asthma, bradycardia, or heart block. |
| Essential tremor | Propranolol, if appropriate | Can treat tremor and lower BP, but not usually selected solely as first-line hypertension therapy. |
| Pheochromocytoma | Alpha-blockade first: phenoxybenzamine or doxazosin; beta-blocker only after adequate alpha blockade | Giving beta-blocker first can cause dangerous unopposed alpha-mediated vasoconstriction. |
| Aortic dissection or acute aortic syndrome | IV beta-blocker first, commonly labetalol or esmolol, in emergency care | Lowers heart rate and shear stress. Requires ICU-level emergency management. |
3. Important “avoid” combinations and cautions
- Do not use ACE inhibitor or ARB in pregnancy.
- Do not combine ACE inhibitor + ARB routinely because kidney injury and hyperkalemia risk increase.
- Avoid beta-blockers in marked bradycardia, second- or third-degree heart block without pacing, and use caution in asthma.
- Avoid verapamil/diltiazem in HFrEF.
- Use thiazides cautiously in gout, hyponatremia, hypokalemia, and severe renal impairment.
- Use ACE inhibitors/ARBs cautiously in bilateral renal-artery stenosis, hyperkalemia, or acute kidney injury.
- In older or frail adults, check for orthostatic hypotension before intensifying treatment.
Quick exam-style summary
- Young adult: ACE inhibitor or ARB
- Older adult / isolated systolic HTN: CCB or thiazide-like diuretic
- Diabetes + albuminuria / CKD + albuminuria: ACE inhibitor or ARB
- Heart failure / post-MI / angina: beta-blocker plus ACE inhibitor/ARB or other guideline-directed cardiac therapy
- Pregnancy: labetalol, nifedipine, methyldopa
- Gout: avoid thiazide if possible; consider losartan
- Asthma: avoid nonselective beta-blocker
- BPH: alpha-blocker may help symptoms, but not first-line BP drug
- Frail or >80 years: start one low-dose drug and monitor symptoms, standing BP, kidney function, and falls risk
Drug selection and BP targets should be individualized by the prescriber because comorbidities, renal function, baseline pulse, pregnancy status, and other medications change the safest choice.

NICE hypertension adults treatment age under 55 55 ACE inhibitor CCB step 2 combination recommendations
ABCD antihypertensive drug classification
This is a traditional, easy-to-remember scheme:
| Letter | Drug class | Examples | Main use |
|---|---|---|---|
| A | ACE inhibitor or ARB | Ramipril, enalapril, lisinopril; losartan, telmisartan | Younger patients, diabetes with albuminuria, CKD with proteinuria, heart failure, post-MI |
| B | Beta-blocker | Bisoprolol, metoprolol, carvedilol, atenolol | Not routine first-line uncomplicated HTN. Use when angina, post-MI, heart failure, AF/tachycardia, pregnancy with labetalol |
| C | Calcium-channel blocker | Amlodipine, nifedipine | Older patients, isolated systolic HTN, Black African/African-Caribbean patients |
| D | Diuretic | Indapamide, chlorthalidone, hydrochlorothiazide | Older patients, salt-sensitive HTN, edema or volume overload; useful as an add-on drug |
Use according to age
Age under 55 years
Start with A
- ACE inhibitor: ramipril, lisinopril, enalapril
- If ACE inhibitor causes cough or angioedema, use an ARB: losartan, telmisartan, valsartan.
Typical combination if BP remains uncontrolled:
- A + C: ACEi/ARB + amlodipine
- Or A + D: ACEi/ARB + thiazide-like diuretic
Exceptions
- Type 2 diabetes, regardless of age: usually start with A.
- Albuminuria / diabetic nephropathy / CKD with proteinuria: ACE inhibitor or ARB is preferred.
Age 55 years or older
Start with C
- A long-acting dihydropyridine CCB, commonly amlodipine.
If CCB causes ankle edema or is unsuitable:
- Use D, preferably a thiazide-like diuretic such as indapamide or chlorthalidone.
Typical combination if BP remains uncontrolled:
- C + A: amlodipine + ACEi/ARB
- Or C + D if A is unsuitable.
Current NICE guidance retains this broad approach: start an ACEi/ARB in those under 55 without type 2 diabetes and not of Black African/African-Caribbean family origin, and a CCB in those aged 55 or above. NICE hypertension recommendations
Age >80 years or frail older adults
- Begin with one drug at a low dose, then increase slowly.
- CCB or thiazide-like diuretic is often used for isolated systolic hypertension.
- Check standing BP, dizziness, falls, renal function, and electrolytes.
- Avoid aggressive BP lowering if it produces symptoms. ESC material suggests considering initial monotherapy and a systolic BP of about 130-140 mmHg if tolerated in very old or frail people. ESC guidance for older adults
Indications based on comorbidity
| Condition | Preferred class or combination | Avoid / caution |
|---|---|---|
| Diabetes with albuminuria | A: ACEi or ARB | Do not combine ACEi + ARB |
| CKD with proteinuria | A: ACEi or ARB | Monitor creatinine and K+ |
| Heart failure with reduced EF | ACEi/ARB or ARNI + evidence-based B such as carvedilol, bisoprolol, or metoprolol succinate; diuretic for congestion | Avoid verapamil/diltiazem in HFrEF |
| Post-MI / angina | A + B is often appropriate | Avoid beta-blocker in marked bradycardia or heart block |
| Atrial fibrillation with rapid rate | B or rate-limiting CCB, diltiazem/verapamil, if no HFrEF | Avoid diltiazem/verapamil in HFrEF |
| Isolated systolic HTN in elderly | C or D | Start low, monitor postural hypotension |
| Black African / African-Caribbean origin, without diabetes | C first; add ARB if required | ACEi monotherapy may be less effective |
| Pregnancy | Labetalol, modified-release nifedipine, or methyldopa | No ACEi or ARB |
| Asthma | Prefer A, C, or D | Avoid nonselective beta-blockers |
| Gout | A or C, with losartan sometimes useful | Avoid thiazide/loop diuretics if they worsen gout |
| BPH | Alpha-blocker can relieve urinary symptoms, but not preferred as routine BP monotherapy | Orthostatic hypotension, especially in older people |
ACE inhibitors are specifically supported in type 1 diabetes with hypertension and albuminuria, while ACE inhibitors or ARBs are appropriate in type 2 diabetes with microalbuminuria. Brenner and Rector’s The Kidney, lines 846-849.
Stepwise combination treatment
Step 1
- Age <55 or diabetes: A
- Age ≥55 or Black African/African-Caribbean origin without diabetes: C
Step 2
Use two drugs from different groups:
-
If started with A, add C or D
- A + C: ramipril + amlodipine
- A + D: telmisartan + indapamide
-
If started with C, add A or D
- C + A: amlodipine + losartan
- C + D: amlodipine + indapamide
Step 3
Use triple therapy:
A + C + D
Example:
- Telmisartan + amlodipine + indapamide
or - Ramipril + amlodipine + chlorthalidone
This is the standard preferred three-drug combination in many guidelines. NICE recommends ACEi or ARB plus CCB plus a thiazide-like diuretic when BP remains uncontrolled on two drugs. NICE visual treatment pathway
Step 4: resistant hypertension
If BP remains uncontrolled despite optimal tolerated A + C + D:
- Confirm adherence and home/ambulatory BP.
- Check for postural hypotension and secondary causes.
- Consider:
- Spironolactone if potassium is ≤4.5 mmol/L, with renal-function and potassium monitoring.
- If potassium is >4.5 mmol/L or spironolactone unsuitable: consider an alpha-blocker or beta-blocker.
- Seek specialist advice if uncontrolled on four drugs.
Important combination rules
Good combinations
- A + C: commonly preferred and may reduce CCB-related ankle edema.
- A + D: useful, especially when volume/salt retention contributes.
- C + D: useful if ACEi/ARB is contraindicated or not tolerated.
- A + C + D: standard triple regimen.
- A + B: useful in hypertension with heart failure, MI, angina, or some arrhythmias.
Avoid
- ACE inhibitor + ARB: do not combine. It increases hyperkalemia, hypotension, and kidney injury without routine benefit.
- Beta-blocker + verapamil/diltiazem: can cause marked bradycardia, heart block, or worsen heart failure.
- ACEi/ARB in pregnancy: contraindicated.
- Thiazide + thiazide-like diuretic together: avoid duplication.
- Nonselective beta-blocker in asthma: generally avoid.
One-line exam answer
ABCD regimen: A = ACE inhibitor/ARB, B = beta-blocker, C = calcium-channel blocker, D = thiazide-like diuretic. In people under 55 years, begin with A; in people 55 years or older, begin with C or D; use A + C or A + D as dual therapy, then A + C + D as triple therapy. Beta-blockers are mainly used when there is a compelling cardiac indication, such as angina, post-MI state, heart failure, or tachyarrhythmia.
