Pharacological Principles Vocab

Question 0

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 a fax of the same drugs given alone.

Answer 0

Synergistic effects

Example 1+1= greater than 2

If two drugs are taken together that are similar in action, such as barbiturates and alcohol, which are both depressants, an effect exaggerated out of proportion to that of each drug taken separately at the given dose may occur. This could be expressed by 1+1= 5. An example might be a person taking a dose of alcohol and a dose of a barbiturate. Normally, taken alone, neither substance would cause serious harm, but if taken together, the combination could cause coma or death.

Question 1

Drug interactions in which the effect of a combination of two or more drugs with similar actions is equivalent to the sum of the individual effects of the same drugs given alone.

Answer 1

Additive effects

Example 1+1=2

Additive effect is the term used when two or more drugs are taken at the same time and the action of one plus the action of the other results in an action as if just one drug had been given. This could be represented by 1+1= 2. An example would be a barbiturate and a tranquilizer given together before surgery to relax the patient.

Question 2

Drug interactions in which the effect of a combination of two or more drugs is less than the sum of the individual effects of the same drugs given alone; it is usually caused by an antagonizing (blocking or reducing) effect of one drug on another

Answer 2

Antagonistic effects

Example 1+1= less than 2

Antagonism is action in which two drugs given together will have an opposite effect on the body. This could be expressed by 1+1=0. An example might be the use of a tranquilizer to stop the action of LSD. Some stimulants will counteract the effects of depressants and thus are used to treat overdoses of barbiturates and narcotics.

Answer 7

Allergic reaction

A measure of the extent of drug absorption for a given drug and route from 0% to 100%

Answer 8

Bioavailability

Question 9

The length of time the concentration of a drug in the blood or tissues is sufficient to elicit a response

Answer 9

Duration of action

Question 10

Protein molecules that catalyze one or more of a variety of biochemical reactions, including those related to the body’s own physiological processes as well as those related to drug metabolism

Answer 10

Enzymes

Question 11

The initial metabolism in the liver of a drug absorbed from the gastrointestinal tract before the drug reaches systemic circulation through the bloodstream

Answer 11

First pass effect

Question 12

The name given to a drug by the United States adopted names counsel. Also called the non-proprietary name, much shorter and simpler than the chemical name and is not protected by trademark

Answer 12

Generic name

Question 13

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%

Answer 13

Half-life

Question 14

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

Answer 14

Idiosyncratic reaction

Question 15

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

Answer 15

Incompatibility

Question 16

Within a joint

Answer 16

Intra-articular

Question 17

Within a sheath

Answer 17

Intrathecal

Question 18

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

Answer 18

Medication error

Question 19

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

Answer 19

Medication use process

Question 20

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

Answer 20

Metabolite(s)

Active metabolites are those that have pharmacological activity of their own, even if the parent job is in active.

Inactive metabolites lack pharmacological activity and are simply drug waste products awaiting excretion from the body

Question 21

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

Answer 21

Onset of action

Question 22

The chemical form of a drug that is administered before it is metabolized by the bodies biochemical reactions into it’s active or inactive metabolites

Answer 22

Parent drug

A parent drug that is not pharmacologically active itself is called a prodrug. A prodrug is then metabolized to pharmacologically active metabolites.

Question 23

What is a parent drug that is not pharmacologically active itself?

Answer 23

A prodrug
