affective disorders Flashcards
describe tyramine toxicity
uptake of tyramine into the Adrenergic neuron via vmat into the synaptic vesicle where it displaces norepinephrine causing reverse transport of norepinephrine out of the neuron.
tyramine is an indirect sympathomimetic=HTN crisis
What are some adverse effects SSRIs- fluoxetine/Prozac escitalopram/Lexapro?
GI distress
sexual dysfunction
serotonin syndrome
Locus coeruleus is a target for PTSD. What receptors?
Locus coeruleus is a target for PTSD. What receptors?
Prazosin-a1
Clonidine a2
Dexmedetomidine a2
Decrease noradrenergic neurotransmission.
all loose tigers are dangerous, send signal of fear renewal/adaptive to amygdala
prelimbic cortex/prefrontal cortex
herb, used for treating depression, downregulation of beta receptors in the brain, probably increases norepinephrine, upregulate CYP enzymes, may cause photo sensitivity and neurotoxicity
Saint Johns wort
can also interact with prescription antidepressants and other drugs
name two selective serotonin reuptake inhibitors
fluoxetine/Prozac
escitalopram/Lexapro
Name two tricyclic antidepressant
Amitriptyline/Elavil
Desipramine/norpramin
Adverse effects include-block sodium channels in the heart in the CNS which can lead to lethal conduction delays and seizures?
TCA
Amitriptyline/Elavil
Desipramine/norpramin
Define affective disorder.
profound emotions without the appropriate situational context.
major depressive order
anxiety slash panic disorder
post-traumatic stress disorder
First line treatment for major depression and anxiety, very selective, decrease side effects
ssri
fluoxetine/Prozac
escitalopram/Lexapro
why don’t you mix SSRI MAOI and triptan(5HT agonist)
Serotonin syndrome-dangerous elevations in serotonin levels or serotonin neurotransmission causes hyperthermia muscle rigidity myoclonus and rapid fluctuations in vital signs
Which MAO metabolizes dopamine?
MAO B for brain
Serotonin-norepinephrine reuptake inhibitor
Cymbalta/duloxetine
Used to treat patients that don’t respond to SSRI, also used to treat fibromyalgia, chronic neuropathic pain, and hot flashes
serotonin norepinephrine reuptake inhibitor
Cymbalta/duloxetine
Major depressive disorder is likely due to decreased_______ and__________ while PTSD is likely due to increased________ and _______ with decreased ________.
major depressive disorder is likely due to decreased dopamine and norepinephrine
PTSD is likely due to increased norepinephrine and glutamate with decreased serotonin
