Amitryptiline, nortryptiline, imipramine, deipramine, clomipramine, dozepin, amoxapine

41
Q

TCA mechanism

A

Amitryptiline, nortryptiline, imipramine, deipramine, clomipramine, dozepin, amoxapine

Inhibit 5HT and NE reuptake

42
Q

TCA use

A

Amitryptiline, nortryptiline, imipramine, deipramine, clomipramine, dozepin, amoxapine

Major depression
OCD (clomipramine)
Peripheral neuropathy
Chronic pain
Migraine prophylaxis
43
Q

TCA toxicity

A

Amitryptiline, nortryptiline, imipramine, deipramine, clomipramine, dozepin, amoxapine

Anti-muscarinic (3' amitriptlyine is worse than 2' nortriptyline); causes confusion and hallucinations in the elderly
Anti-a1 --> Orthostatic hypotension
anti-histamine --> sedation
Prolong QT
Convulsions
Coma
Prolong Cardiac Fast Na+ channels --> Cardiotoxicity (arrhythmias) - prevent with NaHCO3
Respiratory depression
Fever
inc. NE/5HT --> Tremor, insomnia
44
Q

TCA to use in elderly

A

Nortriptyline because 2’ so less anticholinergics

45
Q

NaHCO3

A

prevents arrhythmias with TCAs

46
Q

MAO-I

A

Isocarboxazid, Tranylcypromine, Phenelzine, Selegiline (MAO-B only)

47
Q

MAO-I mechanism

A

Isocarboxazid, Tranylcypromine, Phenelzine, Selegiline (MAO-B only)

Causes increased amine NTs (NE, 5HT, DA)

48
Q

MAO-I use

A

Isocarboxazid, Tranylcypromine, Phenelzine, Selegiline (MAO-B only)

ATYPICAL depression, anxiety

49
Q

MAO-I toxicity

A

Isocarboxazid, Tranylcypromine, Phenelzine, Selegiline (MAO-B only)

CHEESE REACTION - hypertensive crisis with tyramine-rich foods (wine, cheese, beer, smoked meats)
CNS stimulation

Contraindicated with: (to prevent serotonin syndrome)
SSRI
TCA
St. John's Wort
Meperidine (opioid)
Dextromethorphan (opioid)
50
Q

Cheese reaction mechanism

A

Hypertensive crisis with tyramine-rich foods while on MAO-Is

MAO normally breaks down tyramine in GIT
MAO blocked, so tyramine absorbed
Tyramine causes displacement of NE from its vesicles, and thus increases NE release
excess NE causes hypertensive crisis

51
Q

Bupropion mechanism

A

increase NE and DA (don’t know how)

52
Q

Bupropion use

A

ATYPICAL depression

Smoking cessation

53
Q

Bupropion toxicity

A

stimulant
HA
SEIZURES IN ANOREXIC/BULEMICS

*NO sexual AE (SSRIs do)

54
Q

Mirtazapine mechanism

A

a2-antagonist - increases NE and 5HT release

5HT-2 and 5HT-3 - R Antagonists

55
Q

Mirtazapine use/AE

A

ATYPICAL depression
Sedation (good for insomnia)
Increased appetite and weight gain (good for elderly/AIDS)

56
Q

Trazadone mechanism

A

Blocks 5HT-2 and a1-Rs
Weakly inhibits presynaptic reuptake of serotonin
Blocks postsynaptic H1 receptors

57
Q

Trazodone use

A

MC = insomnia (because very high doses needed for atypical depression treatment)

58

sedation (obviously)
nausea
postural hypotension
