Show Answers:

  1. adrenergics (sympathomimetics)
    drugs that stimulate the sympathetic nerve fibers of the autonomic nervous system which use epinephrine or epinephrine-like substances as neurotransmitters
  2. antagonists
    drugs that exert an action opposite to that of another drug or compete for the same receptor sites
  3. anticholinergics (parasympatholytics)
    drugs that block the action of acetylcholine and similar substances at acetylcholine receptors, which results in inhibition of the transmission of parasympathetic nerve impulses
  4. antigens
    • substances that, upon entering the body, are capable of inducing specific immune responses and in turn reacting with the specific products of ┬ásuch responses
    • can be soluble, or particulate, or insoluble
  5. antihistamines
    substances capable of reducing the physiologic and pharmacologic effects of histamine, including a wide variety of drugs that block histamine receptors
  6. antitussive
    a drug that reduces coughing, often by inhibiting neural activity in the cough center of the central nervous system
  7. corticosteroids
    • any of the hormones produced by the adrenal cortex, either in natural or synthetic drug form
    • influence or control many key processes in the body
  8. decongestants
    drugs that reduce congestion or swelling, especially of the upper and lower respiratory tract
  9. expectorants
    drugs that increase the flow of fluid in the respiratory tract, usually by reducing the viscosity of bronchial and tracheal secretions and facilitate their removal by coughing and ciliary action
  10. histamine antagonists
    drugs that compete with histamine for binding sites on histamine receptors
  11. non-sedating antihistamines
    • new meds that work peripherally to block the actions of histamine and therefore don't have the central nervous system effects of many of the older antihistamines
    • also called second-generation antihistamines and peripherally acting antihistamines
  12. reflex stimualtion
    an irritation of the respiratory tract occurring in response to an irritation of the GI tract
  13. sympathomimetic drugs
    • a class of drugs whose effects mimic those resulting from the stimulation of organs and structures by the sympathetic nervous system
    • occupy adrenergic receptor sites and acting as agonists or by increasing the release of norepinephrine at postganglionic nerve endings
