Beta blockers are primarily used for which purpose?

Beta blockers are primarily used to treat hypertension (high blood pressure) and anxiety. They work by blocking the effects of adrenaline on the body's receptors, which results in a decrease in heart rate and blood pressure. This can help manage symptoms of anxiety by reducing physical responses such as a racing heart, allowing individuals to feel calmer. They are often prescribed for individuals who experience performance anxiety, helping them maintain composure in stressful situations.

Additionally, while beta blockers may be misused in sports for their potential calming effects or to manage heart rates, their primary medical applications are indeed for controlling hypertension and alleviating feelings of anxiety. This contrasts with appetite suppression, muscle gain, and endurance enhancement, which are not the intended uses of beta blockers.
