    The name given to a drug by the United States Adopted Names Council. Also called the nonproprietary name. The generic name is much shorter and simpler than the chemical name and is not protected by trademark.

    A hereditary condition in which red blood cells break down when the body is exposed to certain drugs.
  31. Define half-life
    In pharmacokinetics, the time required for half of an administered dose of drug to be eliminated by the body, or the time it takes for the blood level of a drug to be reduced by 50% (also called elimination half-life).
  32. Define idiosyncratic reaction
    An abnormal and unexpected response to a medication, other than an allergic reaction, that is peculiar to an individual patient.
  33. Define incompatibility
    The characteristic that causes two parenteral drugs or solutions to undergo a reaction when mixed or given together that results in the chemical deterioration of at least one of the drugs.
  34. Define intraarterial
    within an artery
  35. Define intraarticular
    Within a joint
  36. Define intrathecal
    Within a sheath (e.g., the theca of the spinal cord, as in an intrathecal injection into the subarachnoid space).
  37. Define medication error
    Any preventable adverse drug event (see above) involving inappropriate medication use by a patient or health care professional; it may or may not cause patient harm.
  38. Define medication use process
    The prescribing, dispensing, and administering of medications, and the monitoring of their effects.
  39. Define metabolite
    A chemical form of a drug that is the product of one or more biochemical (metabolic) reactions involving the parent drug (see later). Active metabolites are those that have pharmacologic activity of their own, even if the parent drug is inactive (see prodrug). Inactive metabolites lack pharmacologic activity and are simply drug waste products awaiting excretion from the body (e.g., via the urinary, gastrointestinal, or respiratory tract).

  41. define parent drug
    The chemical form of a drug that is administered before it is metabolized by the body's biochemical reactions into its active or inactive metabolites (see metabolite). A parent drug that is not pharmacologically active itself is called a prodrug. A prodrug is then metabolized to pharmacologically active metabolites.
  42. Define peak effect
    The time required for a drug to reach its maximum therapeutic response in the body
  43. Define peak level
    The maximum concentration of a drug in the body after administration, usually measured in a blood sample for therapeutic drug monitoring
  44. Define pharmaceutics
    The science of preparing and dispensing drugs including dosage form design
  45. Define pharmacodynamics
    The study of the biochemical and physiologic interactions of drugs at their sites of activity. It examines the physicochemical properties of drugs and their pharmacologic interactions with body receptors.
  46. Define pharmacoeconomics
    The study of economic factors impacting the cost of drug therapy
  47. Define pharmacogenomics
    The study of the influence of genetic factors on drug response, including the nature of genetic aberrations that result in the absence, overabundance, or insufficiency of drug-metabolizing enzymes (also called pharmacogenomics
  48. Define pharmacognosy
    The study of drugs that are obtained from natural plant and animal sources
  49. Define pharmacokinetics
    The study of what happens to a drug from the time it is put into the body until the parent drug and all metabolites have left the body. Pharmacokinetics represent the drug absorption into, distribution and metabolism within, and excretion from the body.

    The broadest term for the study or science of drugs
  51. Define pharmacotherapeutics
    The treatment of pathologic conditions through the use of drugs

  53. Define receptor
    A molecular structure within or on the outer surface of a cell. Receptors bind specific substances (e.g., drug molecules), and one or more corresponding cellular effects (drug actions) occurs as a result of this drug-receptor interaction.
  54. Define steady state
    The physiologic state in which the amount of drug removed via elimination is equal to the amount of drug absorbed with each dose.
  55. Define substrates
    Substances (e.g., drugs or natural biochemicals in the body) on which an enzyme acts.
  56. Define synergistic effects
    Drug interactions in which the effect of a combination of two or more drugs with similar actions is greater than the sum of the individual effects of the same drugs given alone. For example, 1 + 1 is greater than 2 (compare with additive effects).
  57. Define therapeutic drug monitoring
    The process of measuring drug levels to identify a patient's drug exposure and to allow adjustment of dosages with the goals of maximizing therapeutic effects and minimizing toxicity.
  58. Define therapeutic effect
    The desired or intended effect of a particular medication

  62. Define toxicity
    The condition of producing adverse bodily effects due to poisonous qualities
  63. Define toxicology
