Terbutaline should be avoided in patients with ventricular arrhythmias; confirms proarrhythmic effects specific to this oral bronchodilator.
Do orally administered bronchodilators (ephedrine, aminophylline, terbutaline) cause arrhythmogenic effects compared to placebo in patients with ventricular arrhythmia?
Orally administered terbutaline is associated with increased ventricular ectopic beats and ventricular tachycardia, and should not be considered safer than ephedrine or aminophylline in patients with arrhythmias.
