    Study Notes

    Anxiolytic and Hypnotic Drugs

    • Anxiety is a feeling of tension, nervousness, apprehension, or fear.
    • Sedation is the loss of awareness and reaction to environmental stimuli.
    • Hypnosis is extreme sedation, resulting in further CNS depression and sleep.

    Benzodiazepines

    • Adverse effects include drowsiness, confusion, ataxia, cognitive impairment, and potential for "floppy infant syndrome" if used in the third trimester.
    • Use cautiously in patients with liver disease.
    • Effects are enhanced by alcohol and CNS depressants.

    Therapeutic Uses of Benzodiazepines

    • Anxiety disorders: Panic disorder, generalized anxiety disorder (GAD), social anxiety disorder, performance anxiety, post-traumatic stress disorder, obsessive-compulsive disorder, extreme anxiety associated with phobias, and anxiety related to depression and schizophrenia.
    • Alcohol withdrawal symptoms: Chlordiazepoxide, chlorazepate, diazepam, and oxazepam.
    • Sleep disorders.
    • Midazolam: Facilitate amnesia and sedation prior to anesthesia.
    • Lorazepam and diazepam: Drugs of choice for terminating status epilepticus.

    CNS Effects of Benzodiazepines

    • Drowsiness, somnolence, lethargy, ataxia, vertigo, feeling of a "hangover", thinking abnormalities, paradoxical excitement, anxiety, and hallucinations.

    GI Effects of Benzodiazepines

    • Nausea, vomiting, constipation, diarrhea, and epigastric pain.

    Cardiovascular Effects of Benzodiazepines

    • Bradycardia, hypotension (especially with IV administration), and syncope.

    Nursing Implementation for Benzodiazepines

    • Give parenteral forms only when oral forms are not feasible or available, and switch to oral forms as soon as possible.
    • Administer IV medications slowly to avoid cardiac complications.
    • Provide standby life-support facilities in case of severe respiratory depression.
    • Taper dose gradually after long-term therapy, especially in patients with epilepsy, to avoid seizures or withdrawal syndrome.
    • Provide comfort measures such as frequent meals, bathroom access, bowel program, and food with medication if GI upset is severe.

    Advantages of Benzodiazepines over Barbiturates

    • Less potential for addiction.
    • Greater safety margin.
    • Fewer adverse effects.

    "Z-drugs"

    • Oral drugs for short-term treatment of insomnia.
    • Take before bed and devote 4-8 hours to sleep.
    • Use with caution in patients with hepatic or renal impairment.
    • Elderly patients are sensitive, so administer lower doses and monitor closely.

    Diazepam

    • Used to treat muscular disorders or spasticity from degenerative disorders like multiple sclerosis and cerebral palsy.

    Nursing Implementation for Benzodiazepines

    • Do not mix IV drugs with other solutions to avoid drug interactions.
    • Give parenteral forms only when oral forms are not feasible.
    • Administer IV drugs slowly to prevent hypotension, bradycardia, and cardiac arrest.
    • Reduce the dose of narcotic analgesics in patients receiving benzodiazepines to decrease potentiated effects and sedation.
    • Keep patients receiving parenteral benzodiazepines in bed for at least 3 hours.
    • Do not allow ambulatory patients to operate motor vehicles after an injection.
    • Taper dose gradually after long-term therapy, especially in epileptic patients.
    • Provide comfort measures to help patients tolerate drug effects.

    Barbiturates

    • Barbiturates used as anxiolytic-hypnotics include: amobarbital, butabarbital, mephobarbital, pentobarbital, phenobarbital, and secobarbital.
    • They are general CNS depressants inhibiting neuronal impulse conduction in the ascending RAS, depressing the cerebral cortex, altering cerebellar function, and depressing motor output.
