What is one brand name for a B-blocker?

Propranolol is a well-known brand name for a beta-blocker, which is a class of medications primarily used to manage hypertension, anxiety, and certain types of heart conditions. Beta-blockers work by blocking the effects of adrenaline on the beta receptors in the heart, leading to a decrease in heart rate and contractility, ultimately reducing blood pressure and demand on the heart. Propranolol is often prescribed for conditions like performance anxiety and migraines due to its ability to reduce physiological symptoms associated with stress and anxiety.

While Atenolol is also a beta-blocker and could be considered correct, the question focuses on identifying one brand name, and Propranolol is a more established and widely recognized name in this context. The other options listed, Furosemide and Atropine, belong to different classes of medications; Furosemide is a diuretic used to remove excess fluid from the body, and Atropine is an anticholinergic used to increase heart rate in certain medical situations. Thus, they do not fit the criteria of a beta-blocker.
