What is Inderal Used to Treat?

Inderal® is the brand name for the drug Propranolol. It is used in the treatment of anxiety, panic attacks and post traumatic stress disorder (PTSD). It is also used to treat stage fright and because of this it is on the list of banned substances for Olympic athletes. Inderal is also being studied for use in aggressive behavior in traumatic brain injuries.

How Does Inderal Work?

Inderal is a non selective beta blocker which means it blocks the action of both epinephrine and norepinephrine on adrenergic receptors. This reduces heart rate and blood pressure causing calmness and relaxation.
