  15. Anticholinergics work by what type of action

  17. What are some side effects of Atropine
    • Blocks stimulation of the vagus nerve
    • Reduces salivation
    • Decreases GI motility and vomiting
    • Mydriasis (pupil dilation)
  18. Contraindications of Atropine (anticholinergic)
    • Crosses the placenta
    • Pre-existing tachycardia
    • Congestive Heart Faliure
    • Constipation or ileus
    • Can cause other arrhythmias
  19. What are the effects of glycopyrrolate
    • Longer duration of action than atropine
    • Less effect on HR
    • Less suppression of GI motility
    • Does NOT cross the placenta
  20. Types of Major tranquilizers (Neuroleptics)
    • Phenothiazine Derivatives
    • Butyrophenones
  21. Example of a phenothiazine derivative
    • acepromazine
    • chlorpromazine
  22. Example of Butyrphenones
    Droperidol
  23. Actions of major tranquilizers (neuroleptics)
    • Action on CNS
    • Decrease Anxiety
    • Antiemetic effect
    • Antiarrhythmic effect
    • Antihistamine effect
    • Reduces seizure threshold (will cause seizures in know seizure patients)
  24. Contraindications of major tranquilizers
    • shocky, hypotensive or anemic patients
    • cardiovascular patients
    • toxemia
    • hepatics dz
    • geriatric and pediatric

  27. Examples of benzodiazepines
    • Diazepam
    • Telazol
    • midazolam
  28. Actions of Benzodiazepines (minor tranquilizers)
    • Antianxiety
    • skeletal muscle relaxant
    • Anticonvulsant activity
    • appetite stimulant in cat
    • minimal cardiovascular and respiratory effects
    • NO analgesic effect
