Analgesic week 2
Show Answers:

    A substance that binds to a receptor and causes a response. (p. 158)
  5. Agonists-antagonists
    Substances that bind to a receptor and cause a partial response that is not as strong as that caused by an agonist (also known as a partial agonist). (p. 158)
  6. Analgesic ceiling effect
    What occurs when a given pain drug no longer effectively controls a patient's pain despite the administration of the highest safe dosages. (p. 158)
  7. Analgesics
    Medications that relieve pain without causing loss of consciousness (sometimes referred to as painkillers). (p. 152)

    A drug that binds to a receptor and prevents (blocks) a response. (p. 158)
  9. Breakthrough pain
    Pain that occurs between doses of pain medication. (p. 157)
  10. Cancer pain
    Pain resulting from any of a variety of causes related to cancer and/or the metastasis of cancer. (p. 154)
  11. Central pain
    Pain resulting from any disorder that causes central nervous system damage. (p. 154)
  12. Chronic pain
    "Persistent or recurring pain that is often difficult to treat. Includes any pain lasting longer than 3 to 6 months, pain lasting longer than 1 month after healing of an acute tissue injury, or pain that accompanies a nonhealing tissue injury. (p. 153)"
  13. Deep pain
    Pain that occurs in tissues below skin level; opposite of superficial pain. (p. 154)
  14. Gate theory
    The most common and well-described theory of pain transmission and pain relief. It uses a gate model to explain how impulses from damaged tissues are sensed in the brain. (p. 154)
  15. Narcotics
    "A legal term established under the Harrison Narcotic Act of 1914. It originally applied to drugs that produce insensibility or stupor, especially the opioids (e.g., morphine, heroin). Currently used in clinical settings to refer to any medically used controlled substances and in legal settings to refer to any illicit or �street� drug. (Note: This term is falling out of use in favor of opioid and will not be used in this text.)"
  16. Neuropathic pain
    Pain that results from a disturbance of function or pathologic change in a nerve. (p. 154)
  17. Nociception
    Processing of pain signals in the brain that gives rise to the feeling of pain. (p. 153)
  18. Nociceptors
    A subclass of sensory nerves (A and C fibers) that transmit pain signals to the central nervous system from other body parts. (p. 153)
  19. Nonopioid analgesics
    Analgesics that are not classified as opioids. (p. 153)
  20. Nonsteroidal antiinflammatory drugs (NSAIDs)
    "A large, chemically diverse group of drugs that are analgesics and also possess antiinflammatory and antipyretic activity but are not steroids. (p. 154)"
  21. Opioid analgesics
    Synthetic drugs that bind to opiate receptors to relieve pain but are not themselves derived from the opium plant. (p. 152)
  22. Opioid naive
    Describes patients who are receiving opioid analgesics for the first time and who therefore are not accustomed to their effects. (p. 161)
  23. Opioid tolerance
    "A normal physiologic condition that results from long-term opioid use, in which larger doses of opioids are required to maintain the same level of analgesia and in which abrupt discontinuation of the drug results in withdrawal symptoms (same as physical dependence). (p. 156)"
  24. Opioid tolerant
    The opposite of opioid naive; describes patients who have been receiving opioid analgesics (legally or otherwise) for a period of time (1 week or longer) and who are therefore at greater risk of opioid withdrawal syndrome upon sudden discontinuation of opioid use. (p. 157)
  25. Opioid withdrawal
    The signs and symptoms associated with abstinence from or withdrawal of an opioid analgesic when the body has become physically dependent on the substance. (p. 161)
  26. Pain
    An unpleasant sensory and emotional experience associated with actual or potential tissue damage. (p. 152)
  27. Pain threshold
    The level of a stimulus that results in the sensation of pain. (p. 153)
  28. Pain tolerance
    The amount of pain a patient can endure without its interfering with normal function. (p. 153)
  29. Partial agonist
    A drug that binds to a receptor and causes an activation response that is less than that caused by a full agonist (same as antagonist-antagonist). (p. 158)
  30. Phantom pain
    Pain experienced in the area of a body part that has been surgically or traumatically removed. (p. 154)
  31. Physical dependence
    "A state of adaptation that is manifested by a drug class�specific withdrawal syndrome that can be produced by abrupt cessation, rapid dose reduction, decreasing blood level of the drug, and/or administration of an antagonist. The physical adaptation of the body to the presence of an opioid or other addictive substance. (p. 153)"
  32. Psychologic dependence
    A pattern of compulsive use of opioids or any other addictive substance characterized by a continuous craving for the substance and the need to use it for effects other than pain relief (also called addiction). (p. 156)
  33. Referred pain
    Pain occurring in an area away from the organ of origin. (p. 154)
  34. Somatic pain
    "Pain that originates from skeletal muscles, ligaments, or joints. (p. 154)"
  35. Special pain situations
    "The general term for pain control situations that are complex and whose treatment typically involves multiple medications, various health care personnel, and nonpharmacologic therapeutic modalities (e.g., massage, chiropractic care, surgery). (p. 175)"
  36. Superficial pain
    Pain that originates from the skin or mucous membranes; opposite of deep pain. (p. 154)

  38. Tolerance
