Terms in this set (204)
stimulate the
sympathetic nervous
What do adrenergic system tend to mimic
agonists do? norepinephrine and
epinephrine
act on 1 or more adrenergic sites
Adrenergic agonists sites heart, bronchial walls, GI system, bladder, ciliary
of action muscles of eye
Alpha
1 (α₁)
Alpha
What are the four main
2 (α₂)
receptors for adrenergic
Beta1
agonists?
(β₁)
Beta2
(β₂)
There's also dopaminergic receptors
Effects = ↑ cardiac contraction,

AM
vasoconstriction resulting in ↑ BP, dilate pupils
What are the effects of [mydriasis], decrease in salivation, urinary bladder
adrenergic agonists at relaxation, urinary sphincter contraction
the Alpha 1 receptor increases
site
Vasoconstriction so profound no blood flow
Where are the locations vasculature, eyes, bladder, prostate
of Alpha 1 receptors
what does decreased blood flow to organs
overstimulation of
Alpha 1 receptors
lead to
Where are the locations blood vessels, smooth muscle (GI tract)
of Alpha 2 receptors
What are the effects of Inhibits norepinephrine release causing
adrenergic agonists at vasodilation which leads to ↓ BP, decrease in
the Alpha 2 receptor GI tone and motility

AM
Where are beta 1 heart and kidneys(to a lesser degree)
receptors located?
What are the effects of ↑ cardiac contraction, ↑heart rate, ↑ renin secretion →
adrenergic agonists on ↑BP
Beta 1 receptors
Where are Beta 2 all over the body, but
receptors located? mainly in the lungs 2-
lungs
What are the effects of bronchodilation, ↑ blood flow to skeletal
adrenergic agonists on muscles, muscles, relaxes uterus and GI tract,
Beta 2 receptors ↑glucose through glycogenolysis in the
liver
Where are renal, mesenteric, coronary and cerebral arteries
dopaminergic
receptors located?
What are the effects of Stimulation → dilation of blood vessels →↑blood flow
adrenergic agonists on
dopaminergic
receptors
Direct acting (directly stimulate
adrenergic receptor) Drug
example - Epinephrine,
norepinephrine
What are the three
classifications of Indirect-acting (stimulate
adrenergic agonists release of norepinephrine) Drug
example - Amphetamines
