Interactions of nonpeptide angiotensin II receptor antagonists at imidazoline/guanidinium receptor sites in rat forebrain.

abstract：:Torsades de pointes ventricular tachycardia (VT) has been reported in patients taking the nonsedating antihistamine, terfenadine. We performed electrophysiologic studies of 14 isolated guinea pig hearts using the Langendorff technique to assess whether terfenadine exerted actions that could be responsible for inducing...
