Q

Monoamine hypothesis of depression

A

Clinical observations that have provided evidence that maintains depression is caused by functional insufficiency of monoamine transmitters in the brain (serotonin, norepi) based on 2 observations -that depression was induced by reserpine (a drug that depletes monoamines from the brain) and -drugs that treat depression intensify monoamine induced neurotransmission

25
Repetitive transcranial magnetic stimulation
Production of pulsed magnetic fields that can induce electrical currents in the brain and unlike electroconvulsive therapy does not require anesthesia or induction of seizures
26
Suicide risk with antidepressants
Patients taking antidepressants should be watched closely for suicide ideation, worsening mood, and behavioral changes particularly within the first one to two months of therapy or when dosage is changed (theorized to increase energy potentiating risk of acting on suicidal thoughts) most often seen in children thru young adults creating a blackbox warning for all antidepressants
27
Time of response to antidepressants and maintenance treatment
Initial responses develop in 1-3 weeks, max response not seen until 12 weeks, must take at least 1 month before considered a treatment failure, low doses used initially to reduce side effects and gradually increased, if not effective, can increase dosage, switch another drug in same class, switch to drug in different class, combine 2, ad supplemental, can withdraw only via taper but long term maintenance therapy can reduce risk of recurrence for patients with recurrent depressive episodes
28
Only SSRI approved by FDA for treatment of major depression in children

- Major depressive disorder - Generalized anxiety disorder - OCD - PTSD
31
Serotonin syndrome definition
Risk of often combining SSRI's with MAOI or from overdosing or from utilizing St John's wort, often starting 72 hours after starting drug resulting in altered mental status, agitation, confusion, hyperreflexia, tremor, and potentially death
32
Bruxism
Clenching or grinding of teeth usually occuring during sleep that can lead to headache, jaw pain, or dental problems, sometimes a bad side effect of SSRI's
33
SSRI drug interactions
- MAOI can potentiate risk of serotonin syndrome requiring withdrawal at least 14 days before starting fluoxetine - Warfarin can increase effect - St. John's wort can potentiate risk of serotonin syndrome - small risk in pregnancy of neonatal absence syndrome (self resolving)
34
SNRI's function, drug metabolism
- Alongside SSRI considered first line option for treatment of major depression - metabolized in the liver and excreted in the urine
35

38
Before moving a patient from an SSRI to a MAOI, need to have a ____
washout period
39
MAOI inhibitors function, mech of action, drug interactions (5), ADR's (3)
- 3rd line agents for patients not responding to SSRI's or TCA's for treatment of depression - Prevents breakdown of NE and serotonin by MAO causing buildup in the brain - tyramine (amino acid in food), TCA's, SSRI's, SNRI's, sympathomimetics - Postural hypotension, CNS stimulation, liver damage
40
Selegiline (emsam) drug class and indication
- Transdermal MAOI - Approved for treatment of major depression
41
Trazodone (desyrel) function
Moderate blockade of serotonin reuptake that is not effective when used alone but often as an adjunct to an SSRI in patients with insomnia
42
Amoxapine function and drug class
-Similar to antipsychotic agent loxapine, has both antidepressant and neuroleptic properties but can block dopamine receptors inducing parkinson like side effects, tetracyclic antidepressant
43
Buproprion (Wellbutrin) function
Antidepressant similar in structure to amphetamines that has stimulant properties and suppresses appetite, is generally well tolerated and devoid of ADR's associated with TCA's including weight gain and sexual dysfunction
44

45
Bipolar individuals have __x the rate of suicide of the general population
20x
46
Pathophysiology of bipolar disorder

47
Clinical manifestation patterns of mood episodes in bipolar disorder
-Mood episodes can occur in variety of patterns, not all patients alternate repeatedly between mania and depression, episodes can last typically a few months
48
3 major types of bipolar disorder
I - Manic or mixed episode usually with major depressive episodes II - hypomanic episodes with greater major depressive episode, no manic episodes Mixed - manic and depressive symptoms occur simultaneously
49
Drug therapy alone is not optimal for treatment of bipolar disorder, typically needs a combo of psychotherapy and drugs. Drug therapy generally consists of.... Non drug therapy consists of....
....Mood stabilizing drugs, antidepressants, antipsychotics (during manic phase), and adjuncts such as fish oil ....Education and family counseling, ECT
50
Lithium function, mech of action, pharmacokinetics
- Mainstay in treatment for all episodes and subtypes of bipolar disorder highly effective for stabilizing acute mania by reducing euphoria and hyperactivity without causing sedation - Unknown mech of action - Short half life and low therapeutic index, sodium depletion decreases renal excretion of lithium therefore requires sodium levels remain normal
51
Alternative therapeutic uses of lithium (4) and ADR's (4)
- Alcoholism - schizophrenia - migraine - SIADH -Extremely toxic when out of therapeutic range, polyuria, tremor, teratogen in 1st trimester or breast feeding

Alternative drug approved for treatment and prevention of manic episodes in patients with bipolar disorder, like valporate but appears to be less effective in treatment and prevention of depression
54

Used to acutely control symptoms during manic episodes and long term to hep stabilize mood used often in combo with a mood stabilizer such as valproate or lithium
55
Second gen antipsychotics ADR's (3)

130
Barbituates mech of action
- Nonspecific suppression of CNS through binding to GABA receptor complexes at the reticular formation and cerebral cortex causing sedation with no ceiling to amount of CNS depression can produce resulting in death when overdosage - suppresses REM sleep and increases stage 2 sleep resulting in rebound effect upon discontinuation - Tolerance develops to sedative hypnotic effects but not to toxic effects making likelihood of overdose dangerous
