Any chemical that affects the physiologic processes of a living organism | Drug |
The physiologic reactions of the body to a drug. The can be therapeutic or toxic and describe how the function of the body is affected as a whole by the drug. The terms Onset, peak, and duration are used to describe this | Drug effects |
The length of time the concentration of a drug in the blood or tissues is sufficient to elicit a response. | Duration of action |
The initial metabolism in the liver of a drug absorbed from the gastrointestinal tract before the drug reaches systemic circulation through the bloodstream | First-Pass effect |

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%. | Half-life |
An abnormal and unexpected response to a medicine, other than an allergic reaction, that is peculiar to an individual patient. | Idiosyncratic reaction |
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. | Incompatibility |
Any preventable adverse drug event involving inappropriate medication use by a patient or health care professional; it may or may not cause patient harm | medication error |
A chemical form of a drug that is the product of one or more biochemical reactions involving the parent drug. Active are those that have pharmacologic activity of their own, even if the parent drug is inactive. | Metabolite |
_ are those that have pharmacologic activity of their own, even if the parent drug is inactive. | Active metabolites |
_ lack pharmacologic activity and are simply drug waste products awaiting excretion from the body | Inactive metabolites |
The time required for a drug to elicit a therapeutic response after dosing | Onset of action |
The time required for a drug to reach its maximum therapeutic response in the body | Peak effect |
The science of preparing and dispensing drugs, including dosage form design. | Pharmaceutics |
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. | Pharmacodynamics |
The rate of drug distribution among various body compartments after a drug has entered the body. It includes the phases of absorption, distribution, metabolism, and excretion of drugs | Pharmacokinetics |
The broadest term for the study or science of drugs | Pharmacology |
A molecular structure within or on the outer surface of a cell. They bind specific substances, and one or more corresponding cellular effects occurs as a result of this drug-receptor interaction. | receptor |
The physiologic state in which the amount of drug removed via elimination is equal to the amount of drug absorbed with each state | Steady state |
The desired or intended effect of a particular medication | Therapeutic effect |
The ratio between the toxic and therapeutic concentrations of a drug. | Therapeutic index |
Reduced response to a drug after prolonged use | Tolerance |
The condition of producing adverse bodily effects due to poisonous qualities. | Toxicity |
The commercial name given to a drug product by its manufacturer; also called the proprietary name | Trade name |
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. | Trough level |
