Description
Alfuzosin is an α1-adrenergic receptor antagonist that is used clinically to treat benign prostatic hyperplasia (BPH); it relaxes prostatic smooth muscle and increases the urinary flow rate. Alfuzosin also delays cardiac repolarization by increasing the Na+ current. This compound prolongs action potential duration and the QT interval in vivo by increasing the probability of hNa(v)1.5 channel openings and burst duration.
