185
Q

how to treat panic disorder? prognosis?

A

start SSRIs slowly- sertraline(Zoloft) and paroxetine (Paxil). . they are more prone to get panic symptoms from activation of 5HT2A/C. ultimately need higher doses than you do for depression

  • relapses common with discontinuation of therapy.
  • 10-20% have signifiant symptoms that inferrer with fair functioning
  • 50% have mild infrequent symptoms
  • 30-40% remain symptom free after treatment
186

  • 50-90 % have coexisting disorder
187
Q

patient is in an acute manic episode. what should you give? (no counter indications here)

A

lithium + anticonvuslant (carbamazepime or valproic acid). maybe add an atypical antipsychotic (olanzipine, quietiapine, ziprasidone (Geodon)) as adjunct for acute mania

don’t give benzo bc they are addicting

188
Q

side effects of lithium for

  1. pregnant women
  2. person with CHF
  3. person with pain
  4. person with kidney disease, heart disease, thyroid disease
A
  1. ebstein’s abnormality-abnormal parts of tricuspid valve, abnormality of great vessels
  2. caution with thiazide diuretics, ACE inhibitors
  3. caution with NSAIDS
  4. prob bad idea-> causes long term nephrotoxicity, cardiac arrhythmia and T wave flattening, thyrotoxcity
189
Q

monitoring for lithium?

A

YES. levels should be obtained twice weekly until stable. then they should be obtained once every 1-3 months.

therapeutic levels for acute mania are: 0.6-1.2 mEq/L
>1.5: toxic
>2.0: lethal

190
Q

how can carbamazepine (tegretol) cause toxicity and death

A
  • it inhibits neuron depolarization (by binding to Na/K channel) and decreases glutamate release and is anticholinergic
  • toxicity: prolong QRS-> predispose patients to ventricular arrythmias and hypotension
  • OD: antagonizes adenosine receptors-> proconvulsant
  • OD: acute liver failure
191
Q

what is mechanism of valproic acid

A

inhibits Na/Ca channels-> boost GABA-> decrease glutamate

192
Q

what percent of depressed patients respond to placebo? what percent respond (within 2-4 weeks) to SSRI

Q

disorganzied schizophrenia? how does it respond to treatment?

A

194

A

methylphenidate-> inhibit REM sleep cycles

- TCAs as adjunctive are sometimes shown to be good adjuncts with methylphenidate

195
Q

infarct of right vs. left hemisphere vs diffuse bilateral frontal injury

A

left infarct: depression;
right infarct: euphoria, inappropriate indifference, mania;
diffuse bilateral frontal injury: OCD

196
Q

what are sleep changes seen in depressed patients

A
  • increased sleep latency (difficulty falling asleep), early morning awakening, less REM sleep latency (REM sleep occurs earlier in the night)

NOT neuroleptic- more hypotensions;

203
Q

person with weight gain,hypersomnia, and mood reactivity and depression. what do you give?

A

this is atypical depression. give phenelzine (MAO).

204
Q

patient with alcohol withdrawal and elevated transaminases

A

normally you would give long acting like chlordiazepoxide (librium). however, that is metabolized in the liver. use something like oxazepam or lorezapam or temezepam (LOT) which undergo glucuronidation before the liver

205
Q

what is the most likely mechanism for the delayed therapeutic response of SSRI

lithium: thyroid and kidney monitoring

393
Q

how does gabapentin work? where is it excreted

A

GABAergic. excreted renally so caution in renal disease.

394
Q

which mood stabilizer can be rapidly loaded for quicker therapeutic effect

A

valproic acid

395
Q

adverse effects of valproic acid versus carbamazepine

A

both: nausea, vomiting, diarrhea, sedation, lightheadedess, tremor, cognitive blunting, weight gain.
carb: electrolyte abnormalities (hyponatremia), anticholinergic, .
VP: hair loss

396
Q

serious adverse effects of carbamazepine vs. VP

A

both: thrombocytopenia.
Carb:blood dycrasias (aplastic anemia, agranulocytosis,), hepatotox.
VP: hemorrhagic pancreatitis hepatotoxicity polycystic ovaries

397
Q

OD for carbazempine for VP

A

both: tremor, coma, and death

398
Q

Adverse effects of MAOi vs TCA

A

Both: orthostatic hypotension, sexual dysfunction, weight gain, mania in bipolar

TCA: anticholinergic (dry mouth, constipation, blurry vision, urinary retention, confusion, ECG changes), seizures, sedation

MAOI: myoclonus, muscle pains, parasthesias, insomnia

399
Q

Serious side effects in TCA vs MAOI

A

TCA: cardio toxicity (slow cardiac conduction-> arrhythmia, AV block), neurotox (tremor and ataxia; in OD, agitation, delirium, coma, death)

MAOI: tyramine induced HTN crisis

400
Q

Mechanism of action of TCA

A

Antagonism at 5HT and NE pre synaptic re-uptake pumps. Also block muscarinic, alpha adrenergic, and histamine 1 receptors

401
Q

Tertiary amines vs secondary amines

A

Tertiary amines have greater HAM blockade. Newer secondary amines have fewer side effects and are less sedating, and are safer in OD

402
Q

What are 5 tertiary amines

A

Amitryptiline (elavil), clomipramine (anafranil), doxepin (sinequan), trimipramine (surmontil), imipramine(tofranil)

403
Q

Which atypicals can be used for adjunctive treatment for depression

A

Aripiprazole and quitiapine

404
Q

Which two atypicals can be used for bipolar depression

A

Latuda and quetiapine

405
Q

What is side effect of ziprasadone to worry about

A

Possible increased risk of QT prolongation

406
Q

What are 3 secondary amines

A

Desipramine (norpramin), nortryptyline (Pamelor), protryptiline (vivactil)

407
Q

Which TCA is least anticholinergic

A

Desipramine (norpramin)- secondary TCA

408
Q

Which TCA causes least orthostatic hypotension

A

Nortyptiline (Pamelor)

This is the demethylated version of amitryptaline (elavil)

409
Q

Uses for amitryptaline vs doxepin

A

Both are for pain and insomnia. Amytryptiline is for headache. Doxepin is for anxiety.

410
Q

Which MAOI has fewer dietary restrictions s

A

Transdermal selegeline

411
Q

What are three MAOIs

A

Phenylzine, tranylcypramine, transdermal selegeline

412
Q

How long do you have to wait after MAOI before starting ssri

413
Q

Mechanism of action of SNRI

A

Selective antagonism of NE and 5HT reuptake pumps. No HAM- kosher

414
Q

What happens when you discontinue SNRI

A

You can get headache, dizziness, irritability, and fatigue (just like with discontinuation of SSRI)

415
Q

What are serious side effects of mirtazapine

A

Agranulocytosis and other blood dyscrasias

416
Q

mechanism of action of benzos

A

binding site on GABA(A) receptor-> potentiates GABA by causing increased FREQUENCY of chloride channel openings

417
Q

what are three long half life benzos

A

clonazepam, diazepam (valium), chlordiazepoxide (librium)

418
Q

what are three nonbenzo anxiolytics

A

buspirone, hydrozyzine (sedating antihistamine), propranolol (beta blocker)

419
Q

how do nonbenzo hypnotics work

A

all but diphenhydramine and ramelteon are GABAergic

420
Q

which nonbenzo hypnotic leads to progressive tolerance and dependence

A

zolpidem (ambien) and zaleplon (sonata)

421
Q

which nonbenzo hypnotic can you dose in the middle of the night

A

zalpeplon (sonata)- it is short acting

422
Q

which GABAergic nonbenzo hypnotic does not yield tolerance

A

eszopiclone (Lunesta)

423
Q

ramelteon?

A

agonist at melatonin MT-1 and MT-2 receptors, thought to normalize circadian rhythms

424
Q

which nonbenzo hypnotics cause GI probs

A

zolpidem: nausea, vomiting, GI distress.
zaleplon: dizziness and dyspepsia

425
Q

hydrozyzine versus diphenhydramine

A

hydrozyzine is more for situational anxiety, diphenydramine is more for sleep

426
Q

what non chart drugs for ADHD

A

guanfacine and clonidine

427
Q

what drugs cause QT prolongation

A

typicals, TCAs, ziprasadone,

428
Q

which mood stabilizers treat mania

A

lithium, carbamazepine, VP

429
Q

how is clozapine dosed and monitored

A

12.5 mg daily BID + 25/50mg daily-> target to 200-450 mg daily-> + 100 mg/day-> max is 900 mg/day

430

first 6 months: weekly monitoring.
months 6-12: monitor every 2 weeks.
