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.

Features and Benefits

This compound is featured on the Calcium Channels page of the Handbook of Receptor Classification and Signal Transduction. To browse other handbook pages, click here.

Preparation Note

Terodiline has concentration dependent QT prolonging effects and thus the potential for cardiotoxicity. Pharmacogenetic variation in terodiline metabolism could be responsible for cardiotoxicity. We sought to determine whether CYP2D6 (debrisoquine hydroxylase) or CYP2C19 (S-mephenytoin hydroxylase) status is a risk factor

Unfortunately, simultaneous testing of these hypotheses demands complete and detailed data, which are scarce for ecological systems. Hudson's Bay Company data on mink
