Off-label and investigational use
Propranolol is often used by musicians and other performers to prevent stage fright. It has been taken by surgeons to reduce their own innate hand tremors during surgery.
Propranolol is currently being investigated as a potential treatment for post-traumatic stress disorder. Propranolol works to inhibit the actions of norepinephrine, a neurotransmitter that enhances memory consolidation. Studies have shown that individuals given propranolol immediately after a traumatic experience show less severe symptoms of PTSD compared to their respective control groups that did not receive the drug (Vaiva et al., 2003). However, results remain inconclusive as to the success of propranolol in treatment of PTSD.
