bethanechol
urinary retention
bethanechol MOA
muscarinic agonist (psymp)
cholinergic effects stimulate bladder to contract
the cholinergic effects of behthanechol _ bladder contractions
stimulate
physostigmine
reverses anticholinergic toxicity
physostigmine MOA
increases ACh (inhibits its destruction)
which restores cholinergic balance
physostigmine _ ACh
increases
atropine
bradycardia
antidote for anticholinesterase poisoning
atropine MOA
bcard: blocks ACh muscarinic receptors to induce fight or flight
atropine _ ACh muscarinic receptors
blocks
atropine induces what responses
sympathetic
phenylephrine
nasal decongestant
mydriasis
antihypotensive
phenylephrine
constricts small blood vessels in nasal muscoa
phenylephrine causes vaso_
constriction
phenylephrine
dilated pupils by stimulating alpha1 receptors
phenylephrine _ alpha1 receptors
stimulates
prazosin
antihypertensive
phenylephrine _ alpha1 receptors
blocks
phenylephrine causes vaso_
stimulation
lorazepam
insomnia, anxiety, alc withdrawal, pre-op sedation
lorazepam
enhances GABAs to produce calming effects for anxiety
lorazepam _ GABA
enhances
lorazepam
increases GABA, which is diminished in withdrawal
escitalopram
anxiety, depression
escitalopram is a
SSRI
escitalopram
increases levels of serotonin in the brain by inhibiting its reuptake
zolpidem
sedative-hypnotic (insomnia)
zolpidem
enhances GABA activity (promoting sedation)
sertraline is a
SSRI
sertraline
depression
sertraline
increases levels of serotonin for depression
imipramine is a
TCA
imipramine
depression, bedwetting
imipramine
inhibits the reuptake of NE and serotonin, increases their availability
imipramine
inhibits the action of ACh, relaxing the bladder muscles and reducing involuntary contractions
phenelzine
depression
phenelzine is a
MAOI
phenelzine
inhibits MAO, which breaks down serotonin, dopamine, and NE
methylphenidate
increases availability of dopamine and NE (inhibits their reuptake)
promotes activity in specific brain areas
