Executive Summary
Atenolol, a selective beta-1 adrenergic receptor blocker primarily indicated for hypertension and angina pectoris, continues to maintain its position in the cardiovascular therapeutics market. Despite newer drugs entering the market, atenolol remains relevant due to its established safety profile and affordability. Current clinical trials focus on expanding its indications and evaluating long-term safety, particularly in populations with comorbidities. The global atenolol market is projected to grow modestly at a compound annual growth rate (CAGR) of approximately 2-3% over the next five years, driven by aging populations and the persistent prevalence of cardiovascular diseases.

Focus of Current Trials:
- Post-MI arrhythmia prevention: Intensive exploration of atenolol’s anti-arrhythmic efficacy.
- Long-term safety in specific populations: Emphasizing older adults where tolerability issues are critical.
- Comparative effectiveness: Against other beta-blockers such as metoprolol and bisoprolol.
Key Findings:
- Efficacy in arrhythmia prevention appears promising but needs confirmation from large-scale phase 3 studies.
- Safety data remains consistent with known profiles, with expected side effects like bradycardia and fatigue.
- New indications under exploration include early-stage heart failure and hypertensive emergency where beta-blockers have ancillary roles.
