Study Guide 10 Flashcards
Anxiolytics is another term you may see when referring to the anti-anxiety drugs.
Antianxiety drugs
alprazolam (Xanax), chlordiazepoxide (Librium), diazepam (Valium), lorazepam (Ativan)
Examples of Benzodiazepines
Schedule IV controlled substances because of the ability to cause dependency
Benzodiazepines are classified as
Benzodiazepines are used for short term anxiety relief due to the risk of what?
Physical dependence and phycological dependence result from long term used of the benzodiazepines
Benzodiazepines exert their effects how?
They exert their tranquilizing effect by potentiating the effects of gamma-aminobutyric acid (GABA), an inhibitory transmitter
Vistaril works how and where?
It produces its anti-anxiety effect by acting on the hypothalamus and brainstem reticular formation
Vistaril Uses
• Isolated episodes of intense anxiety
• Temporary use for those with severe functional impairment
• Preanesthetic sedation and muscle relaxation
• Convulsion or seizures
• Alcohol withdraw
Vistril Adverse Reactions
• Mild drowsiness or sedation
• Lightheadedness or dizziness
• Headache
• Lethargy, apathy, fatigue
• Disorientation
• Anger
• Restlessness
• Nausea, constipation, or diarrhea, dry mouth
• Visual disturbances
Vistril Dependence
Physical dependance (tolerance): increasingly larger doses required to obtain the desired effect
Withdrawal symptoms can occur when medication is stopped. Therefore, a gradually decreasing dosage schedule (known as tapering) should be used when stopping a benzodiazepine
The client will display anxious behaviors and request to be put back on or increase the dose of he benzodiazepine. This behavior is frequently viewed by others as addiction to the benzodiazepine drugs rather than a fear reaction
Symptoms of Withdrawl
• Increased anxiety and panic
• Fatigue
• Hypersomnia and nightmares
• Metallic taste
• Concentration difficulties
• Headache and tinnitus
• Tremors
• Numbness in the extremities
• Tachycardia, hypertension
• Nausea, vomiting, diarrhea
• Fever and sweating
• Muscle tension, aching, and cramps
• Psychoses and hallucination
• Agitation
• Memory impairment
• Convulsions (possible)
Contraindications to Vistril
• Do not administer anti-anxiety drugs to clients with known hypersensitivity, psychoses, and acute narrow-angle glaucoma
• Pregnancy (category D drugs) and labor
• Reports of floppy infant syndrome manifested by sucking difficulties, lethargy, and hypotonia have been seen in the newborn of a mother using benzodiazepines
• Lactating woman (can cause lethargy and weight loss on infant)
• When clients are in a coma or shock and if the vital signs of the client in acute alcoholic are low
Owing to a specific enzyme reaction, grapefruit or its juice should not be taken if the client is on buspirone and diazepam
Specific Enzyme Reactions
Vistril Interactions
• Alcohol: increased risk for CNS depression or convulsions
• Analgesics: increased risk for CNS depression
• Tricyclic antidepressants: increased risk for sedations and respiratory depression
• Antipschotics: increased risk for sedation and respiratory depression
• Digoxin: increased risk for digitalis toxicity
Anxiolytics are not recommended for
They aren’t recommended for people with a history of substance misuse or addiction
Only short periods such as
1-2 weeks.
When these drugs are given in an outpatient setting, instruct both the client and family about adverse reactions (dizziness, lightheadedness, or ataxia) that can cause a client to fall and become injured. This is very important when the drugs are administered to older patients.
Risk For Injury
Unsteady gait; muscular incoordination
Ataxia
What is excreted more slowly in adults
• Benzodiazepines
Lorazepam and oxazepam are typically used for older adults because
it does not cause excessive sedation and the risk of falling is not as great
Anxiolytics can cause dryness of the
mucous membranes & slower transit in the intestines.
What nursing actions would you recommend?
Frequent sips of water to relieve dry mouth and provide adequate hydration. Chew sugarless gum or suck on hard candy to reduce discomfort or dry mouth. Administer oral antianxiety drugs with food or meals to decrease the possibility of GI upset.
causes sedation, respiratory depression, and coma
Benzo toxicity
Slurred speech, ataxia and altered mental status
Signs & symptoms of Benzo toxicity
Xanax: Anxiety disorders, short-term relief of anxiety, panic attacks
Alprazolam
