Which beta blocker is known to have a formulation for intravenous administration?

Propranolol is the beta blocker with a formulation for intravenous administration, making it suitable for acute management situations, such as treating hypertensive emergencies or controlling tachyarrhythmias. The intravenous form allows for rapid onset of action, which can be critical in acute medical scenarios.

Other beta blockers, while effective in oral formulations for chronic conditions such as hypertension and anxiety, do not have established intravenous formulations. Pindolol, nadolol, and atenolol are primarily available in oral forms and are typically used for long-term management rather than for immediate treatment, which limits their applications in urgent care situations.
