Question

Can you provide a list of key β-blockers, which are categorized as Class II antiarrhythmics?

Answer 1

The key β-blockers that are categorized as Class II antiarrhythmics include Propranolol, Metoprolol, and Atenolol.

Step-by-step explanation:

The key β-blockers that are categorized as Class II antiarrhythmics include:

• Propranolol: This is a non-selective β-blocker that blocks β1 and β2 receptors.
• Metoprolol: This is a selective β1-blocker that specifically blocks the β1-receptor.
• Atenolol: This is another selective β1-blocker.

These medications work by blocking the β-receptors associated with vasoconstriction and cardioacceleration, which helps to improve cardiac function in patients with cardiovascular disease.
