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 ...
Class of antihypertensives that work by causing relaxation of blood vessels as well as a decrease in blood volume, which leads to lower blood pressure and decreased oxygen demand from the heart. [1] Benazepril; Captopril; Enalapril; Fosinopril; Lisinopril; Moexipril; Perindopril; Quinapril; Ramipril; Trandolapril
This contrasts with (ordinary) use dependence, where the efficacy of the drug is increased after repeated use of the tissue. Reverse use dependence is relevant for potassium channel blockers used as class III antiarrhythmics. Reverse use dependent drugs that slow heart rate (such as quinidine) can be less effective at high heart rates. [11]

Ibutilide differs from other class III antiarrhythmic agents in that it activates the slow, delayed inward sodium channels rather than inhibiting outward potassium channels. Sotalol. Sotalol has beta-blocking activity. Approximately 2 to 7 percent of patients taking at least 320 mg/day experience proarrhythmia, most often in the form of TdP. [5]
