Biological Activity

Terfenadine is a histamine H1 receptor antagonist. Also blocks KV11.1 (hERG) and Kir6 (KATP) channels (IC50 values are 204 nM and 1.2 μM respectively). Inhibits the delayed rectifier K+ current (IKr) in guinea pig ventricular myocytes (IC50 = 50 nM). Activity prolongs QT and induces Torsades de pointes (TdP); cardiotoxic in vivo.

Terfenadine was used to assess its action on BK channels
By Anonymous on 12/03/2018
Application: Species: Human

Terfenadine was used to assess its action on BK channels, which are Calcium activated voltage-gated potassium channels that conduct large amounts of potassium ions (K+) across the cell membrane. Results were reliable and reproducible.
