Ch.9: Adrenergic Drugs Flashcards
esomolol is a shorter acting version of which drug?
atenolol
sympathetic action on respiratory system
dilates airways
reduces mucus secretion
better O2 uptake
sym. action on CV system
increase HR, electrical impulse conduction, contractions
vasoconstriction of skin, some blood vessels
vasodilation in skeletal muscle
sym. action on Digestion
decreased salivation, secretions, motility
increased sphincter tone
sym. action on vision
pupil dilation
lens flattens
sym. action on energy mobilization
increased fatty acid release, glycogenolysis, glucagon release
Decreased insulin release
—> elevated blood glucose**
sym. action on brain activity
increased alertness, dilation of cerebral arteries
alpha adrenergic receptors enhance/constrict blood flow
constrict
beta adrenergic receptors enhance/constrict blood flow
enhance
adrenergic agent***
drug that mimics or enhances the actions of endogenous catecholamines EP or NE. Can be direct (activate adrenergic receptors) or indirect-acting (i.e. by inhibiting things that breakdown EP or NE or disrupting metabolism or elimination of NT. have no direct receptor actions)
adrenolytic agent**
drug that blocks (attenuates) actions of EP/NE
adrenoceptor blocker
adrengergic receptor antagonist (rarely used)
adrenergic neuron blocker
have non-receptor actions
primary way EP/NE’s actions are terminated
active reuptake either back into the nerve that released it, or by surrounding cell that can capture and take it up
does cocaine cross BBB?
yes
