Nervous Flashcards
Cholinergic =
Parasympathetic
Adrenergic=
Sympathetic
Alpha 1- adrenergic receptors do what
Vasoconstriction
Alpha-2 receptors of the adrenergic system do what
Generally inhibit skeletal muscle
Beta-1 adrenergic receptors do what
Increase HR, force, and stimulates the renin system
Beta-2 receptors of the adrenergic system does what
Vasodilation, bronchodilation
Direct Cholinergic drugs do what to the body
Mimic acetylcholine which stimulate parasympathetic and can stimulate muscles
Indirect Cholinergic drugs do what to the body?
Inhibit breakdown of acetylcholine
Bethanechol belongs to what drugs category and does what to the body
Cholinergic direct acting, used for GI and urinary tract atony
Metoclopramide is used for what and belongs to what drug category
Cholinergic direct acting, promotes gastric emptying and controls V
Cholinergic drug
Used for tx of urinary retention and Gi atony. Also a antidote to neuromuscular blocking agents
Neostigmine
Organophosphates are commonly used for what
Insecticide dips
What are anticholinergic drugs used for
Decrease GI motility, dry secretions, prevent bradycardia, dilate pupils
Shorter acting anticholinergic drug, increases HR
Atropine
What anticholinergic drug can be used to counteract organophosphates
Atropine
Longer acting anticholinergic drug and used primarily as a preanesthetic
Glycopyrrolate
Adrenergic agonists do what to the body
Stimulate sympathetic receptors mediated by epinephrine or norepinephrine (catecholamines)
Adrenergic agonist drugs are used to
Increase HR, BP, and dilate bronchioles
What adrenergic drugs stimulates all receptors
Epinephrine
What Adrenergic drug is a Beta-1 agonist and is used for short term tx of heart failure
Dobutamine
