Q

What happens if you have too many neurotransmitters in the synapse and they arent able to be picked up by the next cell?

A

They can’t be just left out there…. after some time in the synapse the sender will reuptake the neurotransmitters.

Increased risk of suicide

80
Q

Why might a doctor have a patient stop taking SSRI before a procedure?

A

can effect the way they clot

81
Q

using SHIVERS what are the symptoms of serotonin syndrome (toxicity)?

A

S-Shivering
H- Hyperreflexia and myoclonus
I- increased temp
V- Vital signs instability (tachycar and tachypen & labile bp)
E- encephalopahy (agitiation, delerium & confusion)
R- Restlessness & incoordination
S- Sweating

82
Q

True or false: Discontinuation syndrome will happen to someone who stops taking SSRIs after taking them for the 1st time for 1 week?

A

False- happens to people who have been on SSRIs for extended periods of time.

83
Q

Nursing interventions for serotonin syndrome?

What drug might we give?

A
  1. Discontinue- offending agent
  2. Maintain- safe environment
  3. Monitor- physical and mental status
  4. Administer- Serotonin receptor blockade, Dantrolene or diazepam for muscle rigidity, cyproheptadine (histamine 1 receptor antagonist)
  5. Provide- Reassurance to patient
84
Q

True or false: SSRIs can have a paradoxcical effect on patients who start SSRI therapy esp if under 21 years of age as it can cause a severe sudden onset of SI.

A

True- we will monitor patients extremely close because it can affect anyone even if they have never been suicidal

85
Q

What are some examples of TCA (Tricyclic antidepressants)
(Mine/line)

A
  1. Imipramine
  2. amitriptyline
  3. doxein
  4. desipramine
  5. nortiptyline
  6. clomipramine
  7. maprotiline
  8. Proptriptyline
  9. trimipramine
  10. amoxapine

Imipramine, clomipramine are approved for 8 and up

86
Q

What is the MOA of TCA?

A
  1. Inhibits the reuptake of serotonin (5HT) & norepinephrine (NE) * blocks the cholinergic receptors
87
Q

What are the side effects of TCAs?

A
  1. sedation
  2. mydriasis- dilated pupils
  3. Weight gain
  4. sweating
  5. toxicity
  6. sexual dysfunction
  7. decreased seizure threshold
  8. orthostatic hypotension
  9. Anticholinergic effect
88
Q

True or false- lexapro causes bad discontinuation syndrome

A

True

89
Q

Are TCA’s high or low in lipid solubility?

A

high

90
Q

What is our patient teaching for TCA’s?

A
  1. Avoid alcohol
  2. LETHAL IN OVERDOSE!!!!!
  3. take in the evening
  4. use caution when driving
  5. takes 4-8 weeks to be therapeutic
  6. adherence to medication regimen
91
Q

What is a MAOI and what is its MOA?

A

Monoamine Oxidase inhibitor: Inhibits the enzyme that degrads NE, Dopamine & 5HT

92
Q

What are some examples of MAOIs

A
  1. isocarboxazid
  2. Phenelzine
  3. Tranylcypromine
  4. Selegiline (comes in transdermal patch form for treatment of depression)
93
Q

Why are TCAs more lethal in overdose?

A

Due to the solubility of the drug… it is more rapdily absorbed

94
Q

What are side effects of MAOI’s

A
  1. Muscle cramps
  2. Weight gain
  3. Sexual dysfunction
  4. Anticholinergic effect
    5. Serious food/drug interactions with tyramine
95
Q

True or false: TCA’s are a 1st line drug for treatment of depression?

A

False- Usually never given as a 1st line of treatment. Often given in very small dosages to reduce the chance of OD

96
Q

Patient teaching for MAOI usage includes?

A
  1. Lethal in overdose
  2. Tyramine free diet avoid
    • aged cheeses & meats
    • food with yeast
    • soy

  4. Before taking any other medication notify physician
  5. Use caution when driving
97
Q

Why is there a concern of a hypertensive crisis when using MAOI

A

A MAOI keeps mono amines from being broke down and metabolized. So when the oxidase is inhibited you get a build up of tyramine which is a vassopresser and it will continue to build up and leaad to a hypertensive crisis and ciculatory collapse
