It also shows beta blocker-like and calcium channel blocker-like actions on the SA and AV nodes, increases the refractory period via sodium- and potassium-channel effects, and slows intra-cardiac conduction of the cardiac action potential, via sodium-channel effects. It is suggested that amiodarone may also exacerbate the phenotype associated ...
Like any drug, taking beta blockers comes with side effects. Churchwell said they can cause bronchial constriction, which can be a problem for people with chronic lung disease, asthma and diabetes
Potassium channel blockers Amiodarone; Dofetilide; Dronedarone; E-4031; Ibutilide; Sotalol; Vernakalant; K + channel blocker. Sotalol is also a beta blocker [5] Amiodarone has mostly Class III activity, but also I, II, & IV activity [6] Prevent paroxysmal atrial fibrillation [7] and haemodynamically stable ventricular tachycardia [8] (amiodarone)
Beta blockers vary in their lipophilicity (fat solubility) and in turn in their ability to cross the blood–brain barrier and exert effects in the central nervous system. [76] Beta blockers with greater blood–brain barrier permeability can have both neuropsychiatric therapeutic benefits and side effects, as well as adverse cognitive effects ...
Amiodarone is also safe to use in individuals with cardiomyopathy and atrial fibrillation, to maintain normal sinus rhythm. Amiodarone prolongation of the action potential is uniform over a wide range of heart rates, so this drug does not have reverse use-dependent action. Amiodarone was the first agent described in this class. [4]
The findings indicate the drugs could be considered as a way to manage aggression and hostility in people with psychiatric conditions.

[4] Regarding non-cardiac side effects, they can cause nausea, headache, fatigue, dry mouth, and dry eyes. [4]
Epithelial sodium channel blockers: [6] Amiloride – better tolerated than triamterene; Triamterene – increased renal side-effects; Aldosterone antagonists, also known as mineralocorticoid receptor antagonists: [7] Spironolactone – most widespread use, inexpensive
