Which medication is primarily used for managing anxiety symptoms?

Propranolol is primarily used for managing anxiety symptoms, particularly in situations characterized by performance anxiety or social anxiety. It is a non-selective beta-adrenergic antagonist that works by reducing the physiological symptoms associated with anxiety, such as tachycardia, tremors, and palpitations, which can occur during stressful situations. By blocking the effects of adrenaline, propranolol helps individuals feel calmer and more in control when facing anxiety-provoking scenarios.

In contrast, the other medications listed are used for different purposes or are not primarily indicated for anxiety management. Fluoxetine and sertraline are selective serotonin reuptake inhibitors (SSRIs) that are effective for treating anxiety disorders but typically take longer to show effects and are more frequently used for chronic anxiety conditions. L-tyrosine is an amino acid that is sometimes discussed in the context of improving mood and cognitive function, but it is not a standard treatment for anxiety. Therefore, propranolol stands out as a medication specifically aimed at alleviating the immediate symptoms of anxiety in certain situations.
