26
How long until you see some effect when starting an antidepressant
It is actually 1-2 weeks the patient should see some impovement (2-4 weeks is actually a myth according to maudsley)
27
When should you consider switching an antidepressant
if there is NO response at all by 3-4 weeks (if they experience some relief then don't switch, they may get a full response in a few more weeks)

zoloft
30
Cardiac side effects associated with TCA's
prolonged QTc, tachycardia, hypotension
31
When is suicide risk the highest with antidepressants
when first starting the medication and when discontinuing it
(still good to place people on SSRI beccause treating depression is the best way to prevent suicide and SSRI's is one of the best treatments for now that we have)
32
How long should a patient be on an antidepressant
6-9 months for single episodes
33
do SSRI's treat the cause of depression
NO, they only help to relieve the symptoms

those with cardiac issues and elderly patients, Go for SSRI's
44
Benefits of stimulants in depression
euphoria, wakefulness, and improved fatigue (although modafanil does not provide euphoria but don't have to worry about dependence or tolerance like the other ones)
Not really recommended to use stimulants in depression though

6 weeks
62
When is it appropriate to discontinue an antidepressant abruptly
severe adverese events, like cardiac arrythmias
63
Pharmacodynamic effects of TCA's
- H1 blockers- sedating (be mindful of combining with other sedating meds/substance because it can lead to resp depression)
- Anticholinergic (mindful of combining with antihistamines or antipsychotics)
- a1 blockers (hypotension, espically if getting other a1 blockers)
- arrythmogenic (mindful of electrolyte disturbances or if they are on diuretics)

64
Which TCA's are serotonergic
imipramine, comipramine, amitriptyline
65
Pharmacology risks associated with SSRI

79
Why do TCA's induce arrythmias
because they inhibit sodium and calcium channels leading to prolonged PR, QRS, and QT
ECG is a better measure of toxicity than even levels

Why is abilify helpful with hyperprolactinemia 2/2 to antipsychotic use
it's partial D2 agonism helps counter the antagonism caused by other antipsychotics
195
What is the max dose of abilify for adults and children
30 mg/day
goal should be about 10 mg or when symptoms start to improve
196
What new antipsychotic acts very similarly to abilify
brexipiprazole/rexulit
D2 partial agonist and 5HT1A partial agonist and 5HT2 receptor antagonist
Used for schizophrenia and as an adjunct for depression
Very expensive, so might as well stick with abilify
197
Which antipsychotics are reported to be the most "efficacious"
clozapine and olanzapine, but both have a lot of side effects with the major concerns being metabolic syndrome/weight gain
Clozapine also has other crappy side effects and extenisive monitoring is required
198
Which stimulant is approved for children that are three years old and up
Adderall IR
They have to be six years and older for extended release
199
What do you SSR eyes specifically block in their mechanism of action
The SERT transporter
200
What role does 5HT1a have on neurons that releases serotonin
They are a type of autoreceptor that is responsible for decreasing the amount of serotonin that is released when there is serotonin present and binding to it
201
What happens to the amount of 5HT1A Receptors when a patient has started on an SSRI
The amount of these receptors is down regulated once they are started on an SSRI because the SSRI leads to an increase amount of serotonin that eventually leads to the amounts of those receptors decreasing.
This results in the neuron now being disinhibited enable to fire and release more serotonin which is what we want
Remember that this receptor is responsible originally for decreasing the amount of serotonin that’s released
202
What is the hypothesis for depression that involves BDNF
The hypothesis states that there are decreased levels of BDNF Impatience with depression and that when the patient was started on an antidepressant it can help increase his levels and help improve the Neuronalplasticity of these patients
Brain derived neurotrophic factor
203
Why is the location of serotonin 1a receptors important
The presynaptic receptors are responsible for inhibiting the releases serotonin whereas the receptors that are postsynaptic (in the hippocampus,amygdala, and the cortex) have different functions - My controlling mood cognition and memory
204
How does BuSpar work
It is a serotonin 1a partial agonist and also antagonist
205
What is the proposed mechanism as to why fluoxetine is so activating
It’s inhibition of 5htc receptor
206
What is one of the more activating ssri’s
Prozac
So be cautious when rx to patients with increased anxiety or insomnia
207
What ssri is approved for bulimia?
Prozac!
208
Max dose for wellbutrin so that we decrease the risk for seizures
450 mg, the target dose is 300 mg, but once you get to 450 mg + that is when the seizure risk increases 10 +
If using IR, no single dose should be above 150 mg
