Mental Health Exam 2 Flashcards
Half-life
is the time it takes to remove a portion of the medication from the bloodstream
Depot Injection
is a strategy to improve adherence during maintenance therapy - long acting version of a med -given IM
Tyramine
is found in certain foods and medications and can be problematic for those taking certain types of medication
Neurotransmitters
“neuromessengers” - crosses synapses and attached to a receptor
Pharmacodynamics
what the medication does to the body
Pharmacokinetics
how medications travel through the body
Efficacy
maximum therapeutic effect achievable
potency
amount of drug needed to achieve the maximum effect
steady state
neurons pay attention when this happens
rule of 5s
takes 5 half-lifes to build steady state
off-label use
being used for something different than original testing
black box warning
serious or life threatening side effects
black box warning
serious or life threatening side effects
rebound
temporary return of symptoms
withdrawal
new symptoms resulting from discontinuing a substance
acetylcholine (nm)
too little = DEMENTIA // too much = depression
Serotonin
too little = DEPRESSION, OCD
GABA
too little = ANXIETY
Absorption
stomach to bloodstream
Distribution
movement through the body
Elimination
how it is removed
Psychotropic dugs can impact what?
Nutrition - change in taste, appetite, GI function, absorption, & metabolism
ADHD medications
-methylphenidate (s)
-atomoxetine (ns)
-dextroamphetamine (S)
increase attention
reduce impulsivity
Adverse Effects of ADHD MEDS
-insomnia
-appetite loss (WEIGHT LOSS)
-headache
-abd pain
-lethargy
-RISK OF SUICIDE
monitor growth
Methylphenidate
-stimulant
-monitor height and weight at baseline
-admin right before or right after meals
-provide snacks in evening
Atomoextine
-non-stimulant
-monitor height and weight at baseline
-admin right before or right after meals
-take with food if GI distress occurs
Buckshot
where the med not only hits intended targets but also everything else around it - disfunction and discomfort
Major Classes of Psychotropic Drugs
-Anxiolytics
-Antidepressants
-Mood Stabilizers
-Antipsychotics
-Stimulants
-Memory/Cognitive enhancers
Anxiolytics
used for psychological and somatic symptoms for anxiety disorders
Benzos
-act on GABA nm
-short term use
-highly addictive
-not recommended for elderly
-CI: alcohol and narcotic abuse
Example of Benzos
Diazepam - Valium Clonazepam- Kalonopin Alprazolam -Xanax Lorazepam - Ativan
Adverse of effects of Benzos
-life threatening CNS depression (alcohol, opiates, TCAs)
-interfere with motor ability
-reflexes are impaired
Buspirone
-Atypical anxiolytic
-better for long term tx
-non-addictive
-SE: dizziness, headache, nervousness, nausea, dry mouth, GI distress
CI: renal/liver impairments, lactating women
Antidepressants
-MONITOR FOR SI
-four main groups: Tricyclic
SSRI
MAOI
“Other”
TCA
-Amitriptyline
-Nortriptyline
Buckshot properties of TCA
CI with seizures, increased suicide risks, lethal in overdose (10 day=fatal, give 1 week supply)
SSRIs
FIRST LINE TX
-minimal toxic potential
-SE: N/V, weight changes, sexual changes
-NO grapefruit juice
-risk for serotonin syndrome (St. John Wort)
-Don’t stop taking abruptly
-CI: TCA, MAOI
Common SSRI
-Fluoxetine (prozac)
-Sertraline (Zoloft)
-Citalopram (Celexa)
-Escitalopram (Lexapro)
Serotonin Syndrome
-can be fatal
-begins 2-72 hrs after tx
-presents as mental confusion, abdominal pain, diarrhea, hallucinations, tremors, hyper-reflexia
MAOIs
-used for atypical depression and bulimia
-risk: HTN crisis, orthostatic hypotension, CNS stimulation
MAOIs examples
-phenelzine sulfate (nardil)
-tranylcypromine (parnate)
-isocarboxazid (marplan)
Pt education for MAOIs
must avoid tyramine foods
-must avoid antidepressants
-must avoid OTC cold medications

-valproic acid
-lamotrigine (lamictal)
lithium

can lead to hypothyroidism and impaired kidney function
edu: maintain sodium intake and avoid caffeine
CI: thiazide diuretics and NSAIDs
