4

Idiosyncratic Effect

a different, unexpected or individual effect from the normal one usually expected from a medication; the occurrence of unpredictable and unexplainable symptoms

5

Pharmacodynamics

The process by which medications produce their effects in the body (mechanism of action, onset of action, peak effect, duration of action, half-life)

6

Mechanism of action

The process by which a medication produces its effects

7

Onset of Action

The time it tkaes for a drug to produce a therapeutic response

8

Peak Effect

The time it takes for a drug to reach its maximum therapeutic response

9

Duration of Action

The time the drug concentration is sufficient to elicit a therapeutic response

10

Half Life

The time it takes the body to eliminate half of the medication

11

Pharmacokinetics

The study of absorption, distribution, metabolism, and excretion

12

Receptor Site

where the drug attaches itself to a cell membrane

13

Substance Abuse

any unnecessary or improper use of chemical substances for nonmedical purposes

14

Urticaria

also hives; an acute allergic reaction in which round wheals (welts) develop on the skin, usually accompanied by intense itching

27

Maalox

Magnesium/Aluminum Suspension

28

Medication Absorption

The process by which a medication passes into the bloodstream

29

Medication Distribution

The process by which a medication is transported from its site of absorption to its site of action (receptor site)

30

Medication Metabolism (biotransformation)

The process by which a medication is changed from its original chemical structure into a less active form, usually one that can be readily eliminated by the body
