  1. Adrenergic Antagonist
    A drug that inhibits the action of the adrenergic receptors; also called a sympatholytic drug. Adrenergic antagonists are divided into alpha and beta;

    • Beta- adrenergic antagonists- are used in the treatment of hypertension.
    • Alpha-adrenergic antagonists- are used to decrease the tone of internal urethral sphincters and to decrease blood pressure.
  2. Adrenergic Blocking Agents
    Drugs that block the effects of the adrenergic neurotransmitters; also called sympatholytics.
  3. Adrenergic drugs
    Drugs that simulate the sympathetic nervous system; also called sympathomimetics.
  4. Agonists
    Drugs that bind to a cell receptor and cause action.
  5. Alpha-Adrenergic Agonists
    Drugs that selectively stimulate alpha-adrenergic receptors.
  6. Antagonists
    Drugs that inhibit or block the response of a cell when bound to its receptor.
  7. Anticholinergic Drugs
    Drugs that treat vomiting, diarrhea, and excess gastric secretion by blocking parasympathetic nerve impulses; also called parasympatholytics.
  8. Beta-Adrenergic Block
    Drug that inhibits beta-adrenergic receptors.
  9. Beta-2-Adrenergic Agonists
    Drugs that stimulate beta receptors.
  10. Catecholamines
    A group of chemically related compounds having sympathomimetic action (i.e. epinephrine and norepinephrine)
  11. Cholinergic Agonists
    Drug that functions to enhance the effects mediated by acetylcholine in the CNS, the PNS, or both; also known as parasympathomimetics.
  12. Cholinergic Drugs
    Agents that mimic the action of the parasympathetic nervous system; also called parasympathomimetics.

  13. Cholinergic Receptors
    Sites stimulated by the nerve terminal's release of acetylcholine.
  14. Sympathetic Drugs
    Drugs that function to enhance the effects mediated by epinephrine or norepinephrine in the CNS, the PNS, or both; these drugs decrease intestinal motility, decrease intestinal secretions, and inhibit the action of sphincters.
  15. Receptors (Sympathetic)

    Alpha 1 - blood vessels (causes constriction of arterioles, increasing blood pressure)

    Alpha 2 - Postganglionic nerve endings (causes inhibition of nor and epinephrine)

    Beta 1 - the heart (causes increased HR, conduction, and contractility)

    Beta 2 - the lungs (causes bronchodilation)

    Dopaminergic - renal, mesentary and cerebral arteries (dilation of blood vessels)
  16. Receptors (Sympathetic)
    Alpha 1
    Blood vessels (causes constriction of arterioles, increasing blood pressure)
  17. Receptors (Sympathetic)
    Alpha 2 
    Postganglionic nerve endings (causes inhibition of nor and epinephrine)
  18. Receptors (Sympathetic)
    Beta 1 
    The heart (causes increased HR, conduction, and contractility)
  19. Receptors (Sympathetic)
    Beta 2
    The lungs (causes bronchodilation)
  20. Receptors (Sympathetic)
    Dopaminergic
    Renal, mesentary and cerebral arteries (dilation of blood vessels)
