Wolters Summary - Antidepressants Flashcards
other factors causing depression
beta blockers can cause depression
SSRI MOA
inhibit reuptake of serotonin
SERT rec.
list SSRI
fluoxetine/prozac sertraline/zoloft paroxetine/paxil escitalopram/lexapro citalopram/celexa fluvoxamine
fluoxetine
prozac
sertraline
zoloft
paroxetine
paxil
x
escitalopram
lexapro
citalopram
celexa
SSRI side effects
- GI
- CNS
- erectile dysfunciton
- Anticholinergic
- Hyponatremia
- QTc prolongation
* * can help hot flashes
GI s.e. of SSRI
n/v
dry mouth
CNS s.e. of SSRI
sedation
insomnia
decreased libido
suicidal ideation
drug causing most s.e. of SSRI
paxil/paroxetine
SSRI with longest half life
Prozac
shortest- paxil so have more s.e.
SSRi causing QTc prolongation
escitalopram
citalopram
esp. citalopram
SSRi drug interactions
other serotonergic meds (esp. MAOis and linezolid)
fluoxetine
Fluoxetine and clopidogrel
Prozac is a CYP219 INHIBITOR and Clopidogrel is PRODRUG
so if taking prozac, clopidogrel will not work
same for tamoxifen
SNRI
list
Venlafaxine (Effexor)
Desvenlafaxine
Duloxetine (Cymbalta)
Levomilnacipran
Duloxetine
(Cymbalta)
Venlafaxine
(Effexor)
SSRI MOA
selectively inhibit reuptake of serotonin and norepinephrine
SNRI s.e.
GI/CNS/Urgenital
+ Increase BP (n.e. - no biggie unless uncontrolled HTN)
duloxetine specific s.e.
anticholinergic symptoms
liver toxicity
SNRI drug interactions
other serotonergic meds
duolextine specific
duloxetine SNRI
CYP1A2 inhibitors will increase concentration because duolextine is a 1a2 SUBSTRATE
ex. Cipro/fluvoxamine
bupropion brand
Wellbutrin
MOA bupropion
weak inhibitor of norepinephrine and dopamine reuptake
NO MAO or serotonin
bupropion s.e.
INCREASED seizure risk !!!
also CNS (HA, appetite)
can be used to prevent smoking (Zyban)
what antidepressant would you use for an old lady who is underweight and can’t sleep
mirtazapine
pre-synaptic alpha agonist (increases N.e. and serotonin)
causes sedation and weight gain
which other antidepressant causes priapism
trazodone (trazoBONE)
other antidepressant with BBW of liver toxicity
nefazodone
cyp3a4 inhibitor
TCA MOA
selective inhibition of serotonin and norepinephrine reuptake
antihistamine and anticholinergics effects
Na Channel blocker
TCA s.e.
anticholinergic **
narrow therapeutic index ** (suicidal ideation and seizures, tornadoes de pines)
cardiac problems due to Na Channel blockage
TCA drug list
Amitripyline *
imipramine
despiramine
nortriptyline
(ine/amine)
TCA overdose = which drug
sodium bicarbonate
given with dextrose
MAOis (list)
isocarbozazid
phenelzine
selegiline (parkinsons!) **
tranylcypromine
MAOi MOA
increase endogenous concentrations of dopamine, serotonin, norepinephrine thru inhibiton of monoamine oxidase (that breaks these down)
not first line
MAOi S.E.
hypertensive crisis *** unable to break down tyramine foods
weight gain, thermostatic hypotension, CNS
MAOi drug interactions
2 week wash out req.
other serotonin drugs
also CI with antihypertensive meds
serotonin syndrome
excess serotonin
typically caused by overdose
serotonin syndrome symptoms
hyperthermia (fever)
agitaiton, diaphoresis
increased bowel sounds (diarrhea)
tremor
serotonin syndrome treatment
serotonin antagonist -CYPROHEPTADINE
resistent depression
what do we use if antidepressants don’t work
SGAs
exercise
beers list antidepressants
Anticholinergic symptoms
chronic seizures
SIADH
SSRI
