Propranolol
A non-selective beta-adrenergic blocker used to manage heart rate and reduce myocardial oxygen demand in cardiac patients.
Key Facts
- It decreases the force and rate of cardiac contractions to improve hemodynamic stability.
- In tetralogy of fallot, it helps minimize right-to-left shunting by relaxing the right ventricular outflow tract.
- It is primarily indicated for patients with mild or asymptomatic presentations.
- Careful dose titration is required to prevent adverse effects like excessive bradycardia or hypotension.
