The five main classes in the Vaughan Williams classification of antiarrhythmic agents are: Class I agents interfere with the sodium (Na +) channel. Class II agents are anti-sympathetic nervous system agents. Most agents in this class are beta blockers. Class III agents affect potassium (K +) efflux. Class IV agents affect calcium channels and ...
Prajmaline (Neo-gilurythmal) [1] is a class Ia antiarrhythmic agent [2] which has been available since the 1970s. [3] Class Ia drugs increase the time one action potential lasts in the heart.

[13] [14] Inhibition of the Na v 1.5 channel is specifically involved in its antiarrhythmic effects as a class I antiarrhythmic agent. [15] Quinidine also blocks certain voltage-gated potassium channels (e.g., K v 1.4 , K v 4.2 , hERG , among others), [ 16 ] [ 17 ] acts as an antimuscarinic and alpha-1 blocker , [ 18 ] and is an antimalarial ...

Procainamide (PCA) is a medication of the antiarrhythmic class used for the treatment of cardiac arrhythmias. It is a sodium channel blocker of cardiomyocytes; thus it is classified by the Vaughan Williams classification system as class Ia. In addition to blocking the I Na current, it inhibits the I Kr rectifier K+ current. [1]
Sparteine is a class 1a antiarrhythmic agent and sodium channel blocker. It is an alkaloid and can be extracted from scotch broom.It is the predominant alkaloid in Lupinus mutabilis, and is thought to chelate the bivalent metals calcium and magnesium.
