Definition | Word |
---|---|
drugs that stimulate the sympathetic nervous system. | adrenergics |
Adrenergics are also called: (2) | adrenergic agonists or sympathomimetics because they mimic the effects of the sympathetic neurotransmitters norepinephrine and epinephrine |
adrenergic receptors that are further divided into alpha1- and alpha2-adrenergic receptors and are differentiated by their location on nerves | alpha-adrenergic receptors |
Bodily functions that are involuntary and result from physiologic activity of the ANS. | autonomic functions |
Controls autonomic bodily functions | autonomic nervous system (ANS) |
Located on postsynaptic effector cells- the cells, muscles, and organs that the nerves stimulate. | Beta-adrenergic receptors |
Beta1-adrenergic receptors are primarily in: | the heart |
beta2-adrenergic receptors are located in the: | smooth muscle of the bronchioles and arterioles and in visceral organs |
substances that can produce a sympathomimetic response. They are either endogenous catecholamines (such as epinephrine, norepinephrine, and dopamine) or synthetic catecholamines. | catecholamines |
adrenergic receptors that, when stimulated by dopamine, cause the renal, mesenteric, coronary, and cerebral arteries to dilate and the flow of blood to increase | dopaminergic receptors |
pupillary dilation, whether natural (physiologic) or drug-induced | mydriasis |
topically applied eye medications | ophthalmics |
refers to an increased heart rate | positive chronotropic effect |
causes an increase in conduction through the atrioventricular node | positive inotropic effect |
the space between the nerve ending and the effector organ | synaptic cleft |
paroxysmal chest pain caused by myocardial ischemia | angina |
drugs that bind to adrenergic receptors and inhibit or block neurotransmitters | antagonists |
the characteristic of beta-blockers to inhibit stimulation of the heart by circulating catecholamines | cardioprotective |
beta-blocking drugs that are selective for beta1-adrenergic receptors. | cardioselective beta-blockers |
cardioselective beta-blockers are also called: | beta1-blocking agents |
irregular heartbeat | dysrhythmia |
leaking of fluid from the blood vessel into the tissues | extravasation |
the production of glucose from glycogen in the liver, which is reduced by beta-blockers | glycogenolysis |
action of agents within the beta-blocking class. A drug that mimics the activity of the adrenergic system | intrinsic sympathomimetic activity (ISA) |
attraction to lipid or fat | lipophilicity |
beta-blocking drugs that block both beta1- and beta2-adrenergic receptors | nonselective beta-blockers |
abnormally low blood pressure occuring when a person assumes the standing position | orthostatic hypotension |
drugs used to treat postpartum and postabortion bleeding caused by uterine relaxation and enlargement. They stimulate the smooth muscle of the uterus to contract | oxytocics |
vascular tumor that secretes norepinephrine and stimulates the CNS | pheochromocytoma |
another name for adrenergic antagonists | sympatholytics |
system of classifying antidysrhythmic agents | Vaughan Williams classification |
Albuterol (*) | Ventolin |
Epinephrine (*) | Adrenalin |
Pseudoephedrine (*) | Afrin |
Dobutamine (*) | Dobutrex |
Albuterol is a (category) | selective beta2 adrenergic |
Epinephrine is a (cat.) | natural mixed alpha and beta |
Pseudoephedrine is a (cat.) | stereoisomer of ephedrine |
Dobutamine is a (cat.) | beta1-selective vasoactive adrenergic drug similar to natural dopamine |
Albuterol effect | bronchodilator |
Epiniphrine effects | vasoconstriction, increased BP, cardiac stimulation, dilation of bronchioles |
Pseudoephedrine effect | nasal decongestant |
Dobutamine effect | increases cardiac output by increasing contractility (positive inotropy), which increases stroke volume |

phentolamine effect | reduces peripheral vascular resistance |
phentolamine used to treat | hypertension, pheochromocytoma, extravasation of vasopressors |
prazosin effect | relaxes & dilates the vasculature & smooth muscle around the prostate |
prazosin uses | hypertension, urinary obstruction in men w/ BPH |
metaprolol uses | post-MI, hypertension, early MI |
propranolol uses | angina, hypertension, dysrhythmias, post MI, migraine, tremor, pheochromocytoma |
sotalol effect | antidysrhythmic |
sotalol uses | difficult to treat dysrhythmias |
