Understand the Problem
The question is asking about specific characteristics of certain drugs used in the treatment of hypertension and the pharmacological classification of salbutamol. It also seeks to identify how heart rate influences blood pressure in the context of drug effects.
Answer
D. 2 and 4; Salbutamol is a Beta-2 agonist.
The cardio-selective beta-blockers are Metoprolol, Acebutolol, and Esmolol. Salbutamol can be characterized as a Beta-2 agonist.
Answer for screen readers
The cardio-selective beta-blockers are Metoprolol, Acebutolol, and Esmolol. Salbutamol can be characterized as a Beta-2 agonist.
More Information
Cardio-selective beta-blockers primarily affect the heart by targeting beta-1 receptors. Salbutamol is a beta-2 agonist used primarily for bronchodilation.
Tips
A common mistake is confusing beta-1 selective blockers with non-selective ones. Always check which beta receptors are influenced.
