MH701 - Exam 1 - Big Set
When treating depression w/ anxiety:
-Use less energizing SSRI, Venlafaxine or Duloxetine. Consider Viibryd if others fail. -If using Fluoxetine -- start low and titrate slowly to avoid activation of anxiety -Avoid Wellbutrin as this is too activating; can cause increased anxiety
how to choose antidepressant
-What are the most bothersome symptoms? (Anxious, Energized, Vegetative, Altered Sleep, Altered Sex Drive, Appetite Change, Fatigue, Hypersomnia) -Take advantage of the side effects
Buspirone Acts as
-a partial agonist for serotonin 5-HT1a receptors in the brain -Less sedation and psychomotor impairment -Lack of interaction with alcohol
Acetylcholine (Ach):
-all parasympathetic nerves -major role in attention -learnin -memory Alzheimer's disease is a result of degeneration of ________________ neurons.
positive indications for benzodiazapines
-anxiety/ panic disorders -etoh withdrawal -seizures , insomnia, muscle spasm, -pre-anesthesia sedation, IBS, restless leg, chemo induced n/v
All benzodiazepines have:
-anxiolytic effects -Can cause paradoxical hyperexcitability -Induction of sleep -Anterograde amnesia -Anticonvulsant Effect -Tolerance occurs
Treatment of panic disorder combines
-cognitive-behavioral therapy -self-management techniques -medications *antidepressants *anxiolytic agents
Pharm for Anxiety Pearls
-conservative approach = paroxetine, sertraline citalopram in isolated panic disorder -rapid control of symptoms = brief alprazolam concurrently with ssri and taper benzo -long term Fluoxetine (prozac) effective for panic / depression 1st couple of weeks mimic panic symptoms Klonopin can be taken prn for anticipate panic 0.5-1 mg
In pre-anesthetic doses BZDs will:
-decreases blood pressure -increases heart rate
Panic disorder is associated with
-high utilization of multiple medical services -poor quality of life -high incidence of suicide.
Gamma-amino butyric acid (GABA):
-inhibits transmission from one nerve to the next in CNS -predominant inhibitory neurotransmitter in CNS
Serotonin (5-hydroxytryptamine or 5-HTseries):
-involved with sleep/wake cycles -mood -chronic pain -hunger -more than 20 different receptors.
When treating depression w/ anxiety:
-less energizing SSRI, Venlafaxine or Duloxetine -Viibryd if others fail -if fluoxetine w/ anxiety be sure to start low and titrate slowly to avoid activation of anxiety -Avoid Wellbutrin too activating; increased anxiety
OCD physical abnormality
-lies in pathway that links the frontal lobes of the cerebral cortex with the basal ganglia *MRI suggests loss of tissue in the caudate nuclei, areas in the basal ganglia that filter messages, fails to dampen the obsessional thinking
Dopamine
-most basic neurotransmitter -drives sex, anger/rage -motor behavior -learning -attention =motivation -pleasure -emotion -at least 5 different receptors
Anxiety disorders are linked with marked impairment in:
-physical function -psychological function -quality of life

"Why do you continue to grieve something from long ago?"
a. "Are you considering suicide?"
3. A patient tells the nurse, "I was raped 8 years ago but never told anyone. Nevertheless, the memories haunt me every day. I should be over it by now." Which comment should the nurse offer next? a. "It sounds like you're judging yourself for continuing to struggle with your reaction." b. "Rape is criminal behavior. You should have reported the incident to law enforcement." c. "Are you now ready to engage in counseling to deal with your reactions to this experience?" d. "While it's important to learn from such life events, it's more important to put things in the past."
a. "It sounds like you're judging yourself for continuing to struggle with your reaction."
2. An emergency department nurse talks with a newly admitted victim of reported rape. Which communication should the nurse offer to comfort this patient? a. "You are safe now. I will stay with you in this private room." b. "Would you like your friend to stay with you during your examination?" c. "You made a good decision to come to the hospital after you were raped." d.

35. Treatment of acute bipolar depression would include?
a. Antidepressant monotherapy may precipitate mania or induce rapid-cycling disorders between mania and depression; therefore, use of antidepressants should be avoided entirely or used only short term with a mood stabilizer. b. Antidepressant drugs are often enhanced by a mood stabilizer in the first-line treatment for a first or isolated episode of bipolar depression. A fixed combination of olanzapine and fluoxetine (Symbyax) has been shown to be effective in treating acute bipolar depression for an 8-week period without inducing a switch to mania or hypomania. c. Many patients who are bipolar in the depressed phase do not respond to treatment with standard antidepressants. In these instances, lamotrigine or low-dose ziprasidone (20 to 80 mg per day) may prove effective. d. Electroconvulsive therapy may also be useful for patients with bipolar depression who do not respond to lithium or other mood stabilizers and their adjuncts, particularly in cases in which intense suicidal tendency presents as a medical emergency.

4. The main excitatory neurotransmitter of the central nervous system is
glutamic acid [glutamate] a. It is required for learning and memory; Low levels can lead to fatigue and poor brain activity; neurodegenerative diseases such as Alzheimer's disease, Parkinson's, Huntington's, and Tourette's. b. Increased levels of glutamate can cause death to the neurons (nerve cells) in the brain, Depression, OCD, and Autism.
46. This drug has been linked to abnormal heart rhythm, ventricular arrhythmias, torsades de pointes, and sudden death when injected IV?
haloperidol (Haldol)
Nefazodone (serzone) (usually for sleep) Trazadone (Desyrel) Contraindications
hepatic impairment, MAOI, carbamazepine can decrease effects, lower seizure threshold with other antidepressants, can interfere w potency of htn drugs, interfere with warfarin
absorption
how the drug gets from the site of administration to the blood
SSRI absolute contraindications
hypersensitivity to SSRI bipolar 1 not used without mood stabilizer received MAOI in past 2 weeks hepatic/ renal insufficiency
Serotonin syndrome symptoms
hypertension, tachycardia; myoclonic jerking, tremors; nausea, diarrhea, sweating, hyperthermia; agitation, confusion lability of mood disorientation ataxia
monoamine oxidase inhibitors (MAOIs) adverse effects
hypertensive crisis, orthostatic hypertension, serotonin syndrome
Neuroleptic Malignant Syndrome
hyperthermia, rigidity, mutism, akinesia, confusion, agitation, increased hr&bp may occur any time during DRA treatment
benzos -- Short acting are better
hypnotics with reduced hang-over effect upon wakening
Initial improvement
in 1 to 2 weeks; maximum improvement ranges four to 12 weeks
akathisia
inner restlessness
Primary use of melatonin
insomnia -reduces time to sleep onset -increases total sleep time -may improve quality
Buspirone (Buspar) (anxiolytic) therapeutic indications
insomnia, anxiety, depression, lack sexual dysfunction issues, no dependence issues, good augmenting for anxiety, lacks interaction with etoh
33. Valproate is commonly prescribed as part of a regimen involving other psychotropic agents. If given concurrent with Valproate, Valproate more than doubles concentrations, increasing the risk of a serious rash (Stevens-Johnson syndrome, and toxic epidermal necrolysis)?
lamotrigine (Lamicatal)
Chlorprothixene
low potency antipsychotic orthostatic hypotension
thioridazine
low potency typical antipsychotic orthostatic hypotension
Chlorpromazine (Thorazine)
low potency typical antipsychotic orthostatic hypotension photosensitivity
7. In patients who are ultra-rapid or extensive metabolizers, the concentrations of a drug may be
lower than expected.
Tadalafil (Cialis)
may reduce SSRI-induced sexual dysfunction in men
13. Antidepressants with dual action on both serotonergic and noradrenergic receptors demonstrate greater efficacy in
melancholic depressions / the treatment of major depression.
Target symptoms of Ach-etase inhibitor drugs
memory, behavior, degenerative course
Phosphodiesterase Inhibitors
milrinone (Primacor)
Lamotrigine (Lamictal)
mood stabilizer go low and slow risk of Stevens Johnson
Valproate (Depakote)
mood stabilizer problematic for women of child bearing age. DOUBLES lamotrigine
lithium
mood stabilizer use for suicidal ideation decreases thyroid hormones
how long must s/s of depression be present
more than 2 weeks
remission
removal of almost all s/s for up to 6 months
Compulsions are
repetitive, purposeful behaviors performed in response to an obsession or according to certain rules
recurrence
return of depression s/s after recovery
relapse
return of s/s before full remission or in first several months following remission
to much dopamine
schizophrenia
Barbiturates (short-acting)
secobarbital
education with Buspirone (buspar)
sedation, takes longer to work than benzos, up to 4 weeks bid/tid dosing
Bupropion (Wellbutrin) Contraindications
seizures, HTN, bulimia, insomnia / agitation
donepezil
selective inhibitor of acetylcholinesterace
FDA-Approved for OCD in children
sertraline (6 and older); fluoxetine (7 and older) approved by the FDA for what condition?
Switching pearls
sertraline, escitalopram, venlafaxine, mirtazapine, vortioxetine or bupropion good second agent transient serotonergic may occur early but not usually safety issue Discontinuation most common from serotonergic to non serotonergic (venlafaxine or paroxetine)
Initial therapy with antidepressants
severe: combo of meds and therapy mild-mod: options: meds alone therapy alone combo
Buspar Requires BID - TID dosing due to
short 1/2
Advantages of Buspirone for treatment of Anxiety
similar to benzo in its effect no physical dependence, withdrawal/ abuse less sedation / psychomotor impairment lack of interaction with etoh
28. The standard approach to start (first line) treatment for OCD is (remember this is pharmacology)
start treatment with a SSRI or clomipramine and then move to other pharmacological strategies if the serotonin-specific drugs are not effective.
Education on Benzo
strong propensity for abuse (best for) 1-2 weeks while SSRI kicking in long term / high dose = depression /dementia increased GABA = decreased reactivity of brain benzo prevent pt working through root cause abrupt withdrawal can cause s/s seizures and can potentiate effects of etoh
General principles of psychopharm
study of how drugs interact with specific target sites in the Nervous System to induce changes in mood, thinking or behavior
Prazosin (Minipress) How helpful with PTSD
suppress nightmares, particularly associated with ptsd excessive adrenaline can cause nightmares , blocks the noradrenergic stimulation of the alpha 1 receptor
stepped care model childhood depression
takes into account individual circumstances in treatment of depression
8. Pharmacokinetics best describes what
the body does to the drug.
5. A relative measure of the toxicity or safety of a drug and is defined as the ratio of the median toxic dose to the median effective dose is referred to as
therapeutic index.
Norepinepherine (NE) fight or flight
to much w no actual danger = anxiety / hyperactive to little = depression
most common clinical mistake leading to an unsuccessful trial of an antidepressant drug is:
too low a dosage for too short a time
BZD Withdrawal symptoms
typically mimic those of anxiety disorders
