Biochem/physiol Actions

Terodiline hydrochloride is a non-selective calcium channel antagonist with anticholinergic and vasodilatory activity.
Terodiline is known to increase corrected QT interval (QTc) and decrease resting heart rate in elderly patients. Furthermore, terodiline hydrochloride has been linked to cardiac arrhythmias1.

QT interval prolongation of the electrocardiogram has been associated with the occurrence of life-threatening fatal ventricular arrhythmias. To understand the relationship between preclinical cardiac conduction assessment to clinical outcome, comparisons of free (unbound)-plasma drug concentrations and their associated effects in
