State if each of the voltage-dependent ion channel classes (sodium, potassium and calcium) are commonly targeted by drugs. [3]
Calcium channels are targets - for the treatment of hypertension for example.
Sodium channels are targets - for treatment of epilepsy and to provide local anaesthesia for example.
But, voltage-dependent potassium channels are very rarely targeted
