Beta blockers (β-blockers or BBs) were invented and designed by Sir James Black‚ who was a Nobel Prize winning scientist. Black designed beta blockers to counteract stimulated adrenergic effects. He demonstrated that‚ by blocking the cardiac beta-receptors‚ these agents could cause inhibitory effects on the sinus node (chronotropic effect)‚ atrioventricular node (dromotropic effect)‚ and on myocardial contractility (inotropic effect).1 It is important to note that not all beta receptors (β-receptors)
