Psychiatric Medications Flashcards
Anxiety Medications
2 types
- Two main types:
- Benzodiazepine sedative hypnotic anxiolytics
- Atypical anxiolytic/non barbiturate anxiolytics
other anxiety meds
•Others:
- SSRI - Venlafaxine
- TCA
- MAOI
- CNS stimulates – Ritalin
- Antihistamines – hydroxyzine pamoate (Vistaril)
- Beta blockers – Propranolol – social phobias – off label
- Anticonvulsants – Gabapentin – off label
•
Medication Classification : Benzodiazepine
- Alprazolam (Xanax)
- Lorazepam (Ativan)
- Diazepam (Valium) -
- Chloridiazepoxide (Librium)
- Clorazepate (Tranxene)
- Oxazepam (Serax)
- Clonazepam (Klonopin)
Benzodiazepine
action
Enhances the inhibitory effect of gamma-aminobutyric acid (GABA) in the CNS – rapid and long term relief of anxiety and alcohol withdrawal
benzodiazepine
SE
Side Effects:
- CNS depression
- Addiction
- Tolerance
- Anterograde amnesia
- Toxicity
- Paradoxical response – opposite effect
Atypical Anxiolytic/Nonbarbituate
- Buspirone (Buspar) – Longer use – may take 2-3 weeks to take effect
- Mechanisms unknown – binds to serotonin and dopamine receptors.
- Less Potential for abuse – does not result in sedation
- Uses: Anxiety
Buspirone (Buspar)
contraind/caution
- Do not use with MAOI or until 14 days after MAOI DC
- Avoid use of erythromycin, ketoconazole and grapefruit juice may increase the effects of this class of medication
receptors and action
Dopamine – emotional response, movement
Serotonin – Mood, sexual desire, some social behavior
Anxiolytics – Nursing Interventions
- Monitor vital signs
- Encourage client to rise slowly to avoid dizziness
- Advise not to drive a motor vehicle or operate dangerous equipment
- Benzodiazepines are for short term use only due to risk of addiction
- Warn client not to concurrently take CNS depressants, alcohol, other anxiolytics
- Should take with meals or shortly thereafter to decrease GI discomfort
- Warn client against abrupt discontinuation of medication
- Buspar—may take a couple of weeks to be effective
Medications Classifications for Depression
Tricyclic antidepressants - norepinephrine and serotonin reuptake with anticholinergic side effects
- SSRI* – serotonin - agitation anxiety etc reactions
- MAOIs* – prevent breakdown of norepinephrine, serotonin and dopamine -
SNRI – Depression and anxiety
Atypical Antidepressants
“Start low and go slow”
Tricyclic Antidepressants (TCA)
•Block serotonin and norepinephrine making more of these transmitters available to body.
•Anticholinergic side effects common
- Dry mouth
- Constipation
- Urinary retention
- Increased appetite
- Orthostatic hypotension
- Other treatments – Neuroleptic pain, anxiety, insomnia, fibromyalgia
Tricyclic Antidepressants (TCA)
know this meds
§Amitriptyline (Elavil)
§Doxepine (Silenor)
§Trimipramine (Surmontil)
§Nortriptyline
§
Selective Serotonin Reuptake Inhibitors (SSRI)
- Blocks reabsorption of serotonin releasing more of the neurotransmitter to the body.
- Serotonin syndrome – rare but can occur
- Withdrawal Syndrome – taper dose
- Hyponatremia - < 135 mEq/L
- Bruxism – teeth grinding
- Treatment:
- Major depression Disorder
- Anxiety
- Bulimia
Selective Serotonin Reuptake Inhibitors (SSRI)
medications
citralopram (Celexa)
escitalopram (Lexapro)
paroxetine (Paxil)
sertraline (Zoloft)
fluoxetine (Prosac)
-Avoid grapefruit juice = increases risk of toxicity
Monoamine Oxidase Inhibitors (MAOI)
•Phenelzine
•Increase the amount of Norepinephrine, dopamine, and serotonin in the body.
•Side Effects
- Orthostatic hypotension
- CNS simulation – anxiety
- Hypertensive crisis – Limit tyramine type foods*
•Nursing Care
- Use with caution in diabetes, seizures, or TCA
- Contraindicated if taking SSRI- stop 2 weeks prior
- Treatment of depression and bulimia
