  1. What is the brand name of diazepam?
    Valium
  2. What drug class is Valium?
    Benzodiazepine
  3. What's the mechanism of action for diazepam?
    Intensifies GABA & suppresses the spread of seizure activity through the motor cortex of the brain. Manages stress, anxiety, and alcohol withdrawals. Effective as a premedication for minor orthopedic procedures due to it's muscle relaxant properties, also for cardioversion because it produces amnesia.
  4. What are the indications for Valium?
    • seizures (status epilepticus)
    • induce sedation prior to painful procedures
    • acute anxiety
  5. What are some contraindications for diazepam?
    • hypersensitivity
    • shock
    • coma
    • acute alcohol intoxication
  6. What precautions need to be taken when administering Valium?
    • Can cause local irritation so use a large vein.

    Hypotension, drowsiness, tachycardia, ataxia, amnesia, slurred speech, edema, headache, dizziness, N/V, blurred vision, respiratory depression.

    Hypersensitivity to benzodiazepines, acute narrow angle glaucoma, coma, shock, acute alcohol intoxication.
  17. What are some precautions in using lorazepam?

  18. What are the side effects of Ativan?
    Anteriograde amnesia, sedation, hypertension, hypotension, blurred vision, N/V, confusion
  19. What drug interactions can occur with the use of Ativan?
    Effects of lorazepam will be increased when used in conjunction with other CNS depressants, alcohol, or cimetidine
  20. What is the adult dosage and route of lorazepam?
    1-2 mg slow IVP/IM, q 5 minutes, max 8 mg
  21. What is the pediatric dose and route of Ativan?
    • 0.1 mg/kg slow IVP/IM, max single dose 2 mg
    • May repeat once after 5 minutes
  22. What is the onset and half life of lorazepam?
    • Onset= 1-5 minutes IV, 5-10 minutes IM
    • Half life= 10-20 hours
  23. What functional class is midazolam?
    Benzodiazepine (short acting)
  24. What is the mechanism of action for Versed?
    A short acting benzodiazepine that intensifies activity of GABA. Has CNS depressant, anticonvulsant & anterograde amnesic properties. Relaxes skeletal muscle & induces sleep.
  25. What are the indications for midazolam?
    • Seizures (Status epileticus)
    • To induce sedation prior to painful procedures
  26. What are the contraindications for Versed?
    Hypersensitivity to benzodiazepines, acute narrow angle glaucoma, coma, shock, acute alcohol intoxication
  27. What precautions should be taken with midazolam?
    Patients with COPD, CHF, and/or renal failure
  28. What are some side effects of Versed?
    N/V, blurred vision, retrograde amnesia, excessive amnesia, apnea, hypotension, PVC'S
  29. What interactions does midazolam have?
    Prolonged respiratory depression when given in conjunction with other CNS depressant such as alcohol. Cimetidine increases plasma levels of midazolam.
  30. What is the adult dose and route for Versed?
    1-2.5 mg slow IVP/IM, q 5 minutes, until seizure is abolished

    Blurred vision, dilated pupils, dry mouth, tachycardia, drowsiness, convulsions, hyper/hypotension, papitations, paradoxical bradycardia 9if given too slowly), AV dissociation, urinary retention.
  45. What drug interactions may be encountered with atropine?
    Antihistamines, tricycliclic antidepressants, procainamide may lead to the anticholinergic effects of atropine.
