The beta-adrenergic-blocking drugs block SNS stimulation of the beta-adrenergic receptors by competing with norepinephrine and epinephrine. The beta blockers can be either selective or nonselective, depending on the type of beta-adrenergic receptors they antagonize.
Beta-Adrenergic Blocking Agents. These drugs, commonly called beta blockers, competitively block β receptors in the SANS. As mentioned above, β-receptor
Drugs that can block the beta-one adrenergic receptors will. decrease heart rate. Activation of which kind of receptors causes heart rate to increase? beta-one.
alpha-Adrenergic receptor agonists/antagonists; : beta-Adrenergic Sodium channel blocking drugs; : Potassium channel blocking and opening
Beta-adrenergic blocking drugs Beta-adrenergic blocking drugs prevent epinephrine and norepinephrine from occupying receptor sites on cell membranes. Beta-adrenergic drugs stimulate epinephrine and norepinephrine release so that they can occupy more of the receptor sites.
Class II antiarrhythmic drugs are the beta-adrenergic receptor blocking agents. Beta-adrenergic receptor antagonists are classified as nonselective (antagonize both beta 1 and beta 2 receptors) or selective (antagonize predominantly beta 1 receptors). As a class, all beta-adrenergic receptor antagonists are dose-dependent negative inotropes and
Drugs that bind to but do not activate beta-adrenergic receptors thereby blocking the actions of beta-adrenergic agonists. Adrenergic beta-antagonists are
Adrenergic beta-receptor blockaders (beta-blockers) are drugs that bind to but do not activate beta-adrenergic receptors thereby blocking
Drugs that can block the beta-one adrenergic receptors will. decrease heart rate. Activation of which kind of receptors causes heart rate to increase? beta-one.

Just FYI, one foot of concrete or 3 feet of dirt will block about 90% of radiation. One foot of concrete plus nine feet of dirt will block 99.99% of radiation. That bunker could probably withstand a surface burst of a megaton bomb half a mile away.
