25
List the TCAs
-ipramines and -tylines: | Imipramine, amitriptyline, desipramine, nortryptiline, clomipramine, doxepin, amoxapine.
26
How do TCAs work?
They block the reuptake of NE and Serotonin.
27
Use for TCAs
Mjr depression. Imipramine: bed-wetting Clomipramine: OCD Also used for fibromyalgia (sympt improve w improved ability to sleep). Use nortriptyline for elderly pt/pt w fibromyalgia bc less side effects on ACh.
28
Side effects of TCAs
Sedation alpha-blocking effects (hypotension, sedation, dizziness) atropine-like (anticholinergic) effects- tachycardia, urinary retention Tertiary TCAs (amitriptyline) have more anticholinergic effects than Secondary TCAs (nortriptyline). Desipramine is the least sedating and has a lower seizure threshold.
29
TCA toxicity
Tri-C's: convulsions, coma, cardiotoxicity (arrhythmias) also, respiratory depression, hyperpyrexia-d/t convulsions. Confusion and hallucinations in elderly d/t anticholinergic side effects (so use nortriptyline) Rx: NaHCO3 for CV toxicity
30
List the SSRIs
``` Fluoxetine Paroxetine Sertraline Citalopram Fluvoxamine ```
31
How do SSRIs work?
Sertonin-specific reuptake inhibitors | Usu takes 2-3 wks for them to start working (bridge w amphetamines)
32
Clinical use for SSRIs
``` Depression bulemia basically any anx disorder: generalized anx disorder panic disorder PTSD OCD social phobias can also use for atypical depression ```
33
SSRI toxicity
Less toxicity than TCAs Sexual dysfn #1 reason for discontinuation GI distress Serotonin syndrome w any other drug that increased serotonin (eg MAOI)
34
What is serotonin syndrome?
caused by taking multiple drugs that increase serotonin hyperthermia, musc rigidity (contraction), CV collapse, flushing, diarrhea, seizures Rx: cooling and benzos 1st, then cyproheptadine (serotonin receptor antagonist)
35
Drugs associated with Serotonin Syndrome (so don't give these with SSRIs)
``` Other SSRIs, SNRIs, MAOIs St. John's Wort, kava kava Sibutramine (SNRI for weight loss) Tryptophan Cocaine, amphetamines ```
36
SSRI withdrawal
dizziness, nausea, fatigue, musc aches, anx, irritibility- get all of these with short-acting SSRIs, so give long acting fluoxetine (t1/2 is 9 days) to gradually taper.
37
List the SNRIs
``` Venlafaxine Duloxetine Desvenlafaxine Nefadozone (no sexual side effects) Milnacipran Sibutramine (for weight loss) ```
38
How do SNRIs work?
Inhibit reuptake of both serotonin and NE
39
What are SNRIs used for?
Depression Velafaxine- also used in gen anx disorder Duloxetine- used for diabetic peripheral neuropathy Duloxetine has a greater effect on NE.
40
Toxicity of SNRIs
Increased BP is most common | Also, stimulant effects, sedation, nausea
41
List MAOIs
Phenelzine Tranylcypromine Isocarboxazid Selegiline (an MAO-B inhibitor, but not an anti-depressant. used for parkinsons)
42
Mechanism of MAOI
Nonselective MAO inhibition, leading to increased levels of amine NTs (Dopa, NE, Epi, Serotonin) bc MAO is inhibited and doesn't break them down as usual
43
Clinical use for MAOIs
Atypical depression Anx Hypochondriasis (hypochondriac)
44
Toxicity for MAOIs
HTN crisis when ingesting food with tyramine (wine, cheese, beer, soy sauce, any food that's aged) HTN crisis with Beta-agonists CNS stimulation Contraindicated with SSRIs or meperidine (narcotic analgesic) to prevent serotonin syndrome MAOI washout period- wait 2 wks before starting or after finishing MAOIs to avoid any interactions w other antidepressants
45
What are the atypical antidepressants?
Bupropion (wellbutrin) NDRI Mirtzapine (a tetracyclic) Trazodone (a tetracyclic) Maprotiline
46
What atypical antidepressants are often used with SSRIs?
Buproprion (NDRI) and Trazodone
47
Buproprion
NDRI, Atypical antidepressant Also used for smoking cessation Increases NE and dopamine by unknown mech (so good w SSRI to increase serotonin and therefore cover all NTs) Toxicity: stimulant effects (tachycardia, insomnia- so take in morning); headache. No sexual side effects. Can cause seizure in bulemics or in anyone w hx of seizures or when given w anything that lowers the seizure threshold
48
Mirtzapine
Atypical antidepressant, tetracyclic. Alpha2 antagonist (so increases rls of NE and serotonin), and potent serotonin receptor antagonist Good for elderly pt w decreased appetite and insomnia (use side effects to advantage) Toxicity: sedation, decreased appetite, weight gain, dry mouth (there are anti-histamine side effects)
49
Maprotiline
Atypical antidepressant Blocks NE reuptake Toxicity: sedation, orthostatic hypotension
50
Trazodone
Atypical antidepressant, tetracyclic. Primarily inhibits serotonin reuptake. Used for insomnia (esp in elderly) and at high doses for antidepressant Toxicity: sedation, nausea, priapism (trazoBONE), postural hypotension
51
Amytriptylline side effects
``` Amytriptylline = TCA dry mouth tinnitus blurred vision mania these are mostly due to amytriptylline's anti-cholinergic activity ```
52
Cyclothymia vs dysthymia
Cyclothymia - milder form of bipolar, >2 years (think cyclic) Dysthymia - milder form of depression >2 years (D for depression)
53
Mech of action for benzodiazapines
facilitate GABA by increasing frequency of Cl- chnl opening

physiological tolerance and dependence w sympt of withdrawal (tremor, tachycardia, HTN, malaise, nausea, DTs) when intake is interrupted complications - alcoholic cirrhosis, hepatitis, pancreatitis, peripheral neuropathy, testicular atrophy, sat night palsy (compress radial nerve), aspiration pneumonia Alch is a diuretic, so it causes tubular dysfn and will decrease Mg2+ levels- give alcoholics Mg2+ in the ER, esp if they are having heart problems.

Flumazenil
141

143
CAGE questionnaire
``` Alch screening: Cut back Annoyed (when ppl ask you abt it) Guilty Eye-opener ```
144
Rx for alcoholic with hypoglycemia
Give B1/Thiamine BEFORE giving glucose. Alcoholics have impaired gluconeogenesis- they can't generate glucose. But, if you just give them glucose, will cause Werenke-Korsakoff. So give B1 first, then can give glucose.
145
What's in a banana bag?
thiamine (B1), folate, multivitamines, Mg2+ | give to alcoholics
