What generic medication is a non-selective betablocker used to treat congestive heart failure?
Beta-3 adrenergic antagonist A Beta-3 adrenergic antagonist (β-adrenoceptor antagonist) is an adrenergic antagonist which blocks the Beta-3 adrenergic receptors of cells, with either high specificity (an antagonist which is selective for β adrenoceptors) like L-748,328, L-748,337 and SR 59,230A or non-specifically (an antagonist for β and for β or β adrenoceptors) like the non-selective betablocker Carvedilol.
Procainamide Procainamide is a medication of the antiarrhythmic class used for the treatment of cardiac arrhythmias. It is classified by the Vaughan Williams classification system as class Ia; thus it is a Na+ channel blocker of cardiomyocytes. In addition to blocking the "I" current, it inhibits the "I" rectifier K+ current. Procainamide is also known to induce a voltage-dependent open channel block on the batrachotoxin (BTX)-activated sodium channels in cardiomyocytes.
