Beta Blockers are a group of prescription medications commonly used to manage heart-related conditions and certain other health issues. They work by blocking the effects of adrenaline (epinephrine), which slows down the heart rate and reduces blood pressure.
These medications are widely prescribed for both cardiovascular and non-cardiovascular conditions.
How Beta Blockers Work
Beta blockers act on beta receptors in the heart and blood vessels. By blocking these receptors, they:
- Reduce heart rate
- Lower blood pressure
- Decrease the heart’s workload
- Improve blood flow
This helps protect the heart and reduces the risk of complications.

1. Selective Beta Blockers
- Target mainly the heart
- Fewer respiratory side effects
2. Non-Selective Beta Blockers
- Affect both heart and lungs
- Used for broader treatment
3. Mixed Alpha and Beta Blockers
- Relax blood vessels and reduce heart activity
- Often used in heart failure cases
