Key result
Atenolol is better suited for individuals with heart conditions due to its cardioselectivity, whereas the non-selective beta-blocker Propranolol is valuable for treating migraines and anxiety.
Why the study?
Hypertension remains a leading global risk factor for cardiovascular diseases, motivating a comparison of the efficacy, safety, and pharmacological profiles of various beta-blocker generations.
Do different beta-blockers (e.g., atenolol vs. propranolol) differ in efficacy and safety for managing hypertension and related conditions?
Do different beta-blockers (e.g., atenolol vs. propranolol) differ in efficacy and safety for managing hypertension and related conditions?
Atenolol and propranolol have distinct pharmacological profiles and side effects, making cardioselective atenolol preferable for cardiovascular conditions and non-selective propranolol suitable for broader uses like migraines and anxiety.
May inform condition-specific beta-blocker selection; leaves open need for randomized head-to-head trials.
Hypertension remains a leading risk factor for cardiovascular diseases globally.Beta-blockers have been a cornerstone in antihypertensive therapy.This study aims to compare the efficacy, safety, and pharmacological profiles of various beta-blockers, including first, second, and third generations, in the management of hypertension. Classification of Beta-BlockersBeta-blockers are classified into three generations based on their pharmacological properties: First Generation: Non-selective 1 and 2 blockers (e.g., Propranolol, Nadolol) Second Generation: Cardioselective 1 blockers (e.g., Metoprolol, Atenolol) Third Generation: Non-selective blockers with additional vasodilatory properties (e.g., Carvedilol, Nebivolol) Comparative EfficacyA meta-analysis of 26 randomized controlled trials involving 19,170 patients assessed the impact of beta-blockers on mortality in heart failure patients.The study found a significant reduction in all-cause mortality with beta-blocker use, irrespective of heart failure etiology.Comparative studies between nebivolol and other antihypertensive agents revealed that nebivolol was associated with a higher risk of stroke compared to ACE inhibitors and thiazide diuretics.

Jadhav et al. (2025) conducted a review in Hypertension. Atenolol and Propranolol was evaluated. Atenolol is better suited for individuals with heart conditions due to its cardioselectivity, whereas the non-selective beta-blocker Propranolol is valuable for treating migraines and anxiety.
