心房顫動
XEN-D0101 is an experimental drug that was developed to treat atrial fibrillation. Xention, a biopharmaceutical company based in Cambridge, United Kingdom, created XEN-D0101 along with other ion channel-modulating drugs. XEN-D0101 is a selective antagonist of the voltage-gated potassium channel Kv1.5. Atrial fibrillation is the main focus of Xention’s drug development, as it is the most common cardiac arrhythmia (irregular heart beat) seen in patients.
