What type of beta blocker is carvedilol?
Carvedilol is a non-selective beta blocker (it blocks both beta-1 and beta-2 receptors). [1]
It also has alpha-1 blocking activity, which helps lower blood pressure. [1]
Is carvedilol considered a beta-1 selective (cardioselective) blocker?
No. Because carvedilol blocks both beta-1 and beta-2 receptors, it is not beta-1 selective (cardioselective). [1]
Why does the “alpha-1 blocker” part matter?
The alpha-1 blocking effect is part of how carvedilol helps reduce blood pressure, in addition to slowing heart rate and reducing cardiac workload through beta blockade. [1]
What conditions is this type of beta blocker used for?
Carvedilol is commonly used for heart-related conditions such as heart failure and high blood pressure, reflecting its combined beta-blocking and alpha-blocking effects. [1]
What to watch for if someone has asthma/COPD?
Because carvedilol is non-selective (beta-2 blockade), it can be more likely than beta-1 selective blockers to affect bronchospasm in people with asthma or some forms of COPD. This is a key reason clinicians choose carefully among beta blockers. [1]
Does carvedilol differ from metoprolol or bisoprolol?
Yes. Metoprolol and bisoprolol are generally beta-1 selective, while carvedilol is non-selective with additional alpha-1 blockade. [1]
