Aliases: Sumial, Ciplar, Inderal, Deralin, Dociton, hemangeol, innopran
Summary
Propranolol is a non-selective beta blocker primarily used for cardiovascular conditions but widely prescribed off-label for performance and situational anxiety. It reduces physical anxiety symptoms (tremor, palpitations, sweating) but does not address psychological causes. Contraindicated in asthma and COPD due to bronchoconstriction risk.
