The movement of a drug from its site of administration into the blood.


The movement of drugs throughout the body


The enzymatic alteration of drug structure (aka biotransformation)

The method by which drugs are inactivated or bio-transformed by the body.


Elimination of a medication from the body.

BEERS Criteria

A list of medications that are generally considered inappropriate when given to elderly people.

Drug Enforcement Administration (DEA)

Enforces the Controlled Substances Act.

First Pass Effect

The concentration of a drug is greatly reduced before it reaches the systemic circulation.

A drug's efficiency may be affected by the degree to which it binds to the proteins within blood plasma.

The less bound a drug is, the more efficiently it can traverse cell membranes or diffuse into or out of a cell.

The more protein available, the longer protein bound drugs remain in the body.


The study of drug movement throughout the body. (absorption, distribution, metabolism, excretion)


What drugs do to the body and how they do it.

(The study of biochemical and physiological effects of drugs and the molecular mechanisms by which those effects are produced.)


The use of drugs to treat, prevent or diagnose disease or prevent pregnancy.
