    • headaches
    • restlessness
    • insomnia
    • urinary retention
    • nausea/vomiting
  17. What is the main purpose of adrenergic blocking drugs?
    • used to disrupt the sympathetic nervous system
    • block impulse transmission at adrenergic neurons or receptor sites
  18. What are the two classification of adrenergic blocking drugs?
    • alpha-adrenergic blockers
    • beta-adrenergic blockers
  19. What is the function of adrenergic blocking drugs?
    • interfere or block storage and reuptake of catacholamine by neurons
    • relax smooth muscles in blood vessels
    • increase dilation of blood vessels
    • decrease blood pressure

  23. What is the mechanism of action with beta-adrenergic blockers?
    prevent stimulation of the SNS by inhibiting the action of catacholamine at beta-adrenergic receptor sites
  24. What are beta-adrenergic blockers primarily functions?
