Q

Half-life

A

In pharmacokinetics, the time required for half of an administered does of drug to be eliminated by the body, or the time it takes for the blood lever of a drug to be reduced by 50%.

25
Q

Idiosyncratic reaction

A

An abnormal and unexpected response to a medication, other than an allergic reaction, that is peculiar to an individual patient.

26
Q

Incompatibility

A

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.

27
Q

Intraarterial

A

Within an artery

28
Q

Intraarticular

A

Within a joint

29
Q

Intrathecal

A

Within a sheath EX: the theca of the spinal cord or subarachnoid space.

30
Q

Medication error

A

Any preventable adverse drug event involving inappropriate medication use by a patient or health care professional; it may or may not cause patient harm.

31
Q

Medication use process

A

The prescribing, dispensing, and administering of medications, and the monitoring of their effects.

32
Q

Metabolite

A

A chemical form of a drug that is the product of one or more biochemical reactions involving the parent drug.

33
Q

Active metabolite

A

Those that have pharmacologic activity of their own, even if the parent drug is inactive.

34
Q

Inactive metabolite

A

Lack pharmacologic activity and are simply drug waste products awaiting secretion from the body.

35
Q

Onset of action

A

The time required for a drug to elicit a therapeutic response after dosing.

36
Q

Parent drug

A

The chemical form of a drug that is administered into its active or inactive metabolites. A parent drug that is not pharmacologically active itself if called a prodrug.

37
Q

Peak effect

A

The time required for a drug to reach its maximum therapeutic response in the body.

38
Q

Peak level

A

The maximum concentration of a drug in the body after administration, usually measured in a blood sample for therapeutic drug monitoring.

39
Q

Pharmaceutics

A

The science of preparing and dispensing drugs, including dosage form design.

40
Q

Pharmacodynamics

A

The study of the biochemical and physiologic interactions of drugs at their sites of activity. It examines the physiochemical ptoperities of drugs and their pharmacologic interactions with body receptors.

41
Q

Pharmacoeconomics

A

The study of economic factors impacting the cost of drug therapy.

42
Q

Pharmacogenomics

A

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.

43
Q

Pharmacognosy

A

The study of drugs that are obtained from natural plant and animal sources.

44
Q

Pharmacokinetics

A

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.

45
Q

Prodrug

A

An inactive drug dosage form that is converted to an active metabolite by various biochemical reactions once it is inside the body.

46
Q

Receptor

A

A molecular structure within or on the outer surface of a cell.

47
Q

Steady state

A

The physiologic state in which the amount of drug removed via elimination is equal to the amount of drug absorbed with each dose.

48
Q

Substrates

A

Substances (drugs or natural biochemicals) on which an enzyme acts.

49
Q

Synergistic effects

A

Drug interactions in which the effect of a combination of two or more drugs with similar actions is greater that the sum of the individual effects of the same drugs given alone. EX: 1+1=more than 2

50
Q

Therapeutic drug monitoring

A

The process of measuring drug levels to identify a patient’s drug exposure and allow adjustment of dosages with the goals of maximizing therapeutic effects and minimizing toxicity.

51
Q

Therapeutic effect

A

The desired or intended effect of a particular medication

52
Q

Therapeutic index

A

The ratio between the toxic and therapeutic concentrations of a drug.

53
Q

Tolerance

A

Reduced response to a drug after prolonged use.

54
Q

Toxic

A

The quality of being poisonous.

55
Q

Toxicity

A

The condition of producing adverse bodily effects due to poisonous qualities.

56
Q

Toxicology

A

The study of poisons, including toxic drug effects, and applicable treatments.

57
Q

Trade name

A

The commercial name given to a drug product by it’s manufacturer; also called the proprietary name.

58
Q

Trough level

A

The lowest concentration of drug reached in the body after it falls from its peak level, usually measured in a blood sample for therapeutic drug monitoring.
