Cards

Term
Pharmacology
Definition
the study of drugs and their actions on living organisms
Term
The 4 drug names?
Definition
Chemical name, generic (common) name, official name (FDA), and trademark, proprietary, or brand name (registered name)
Term
Prescription drugs
Definition
Require an order by a health professional who is licensed to prescrive
Term
Non-prescription drugs
Definition
Also known as OTC (Over the Counter) drugs, do not require a prescription
Term
Illegal drugs
Definition
Used for non-theraputic purposes
Term
American Drug Index
Definition
an index of all medicines available in the U.S.
Term
Schedule I Drugs
Definition

1. high potential for abuse

2. no currently accepted medical use

ex: LSD, marijuana, heroin

Term
Schedule II Drugs
Definition

1. high potential for abuse

2. accepted medical use

ex: amphetamines, morhpine, methadone

Term
Schedule III Drugs
Definition

1. high potential for abuse, but less than I and II

2. accepted medical use

ex: empirin with codeine, Lortab, tyenol with codeine

Term
Schedule IV Drugs
Definition

1. low potential for abuse

2. accepted for medical use

ex: diazepam (valium), phenobarbital

Term
Schedule V Drugs
Definition

1. low potential for abuse, compared with IV

2. currently accepted medical use

ex: lomotil, Roitussin AC

Term
Preclinical research
Definition
phase of new drug development which begins with discovery, synthesis, and purificaiton of the drug
Term
Clinical research, Phase 1
Definition

studies the experimental drug's properties

ex: safe routes of administration

safe dosage range

metabolism

 

requires volunteers numbered 20-100 

treated for 4-6 weeks

if successful, moves to phase 2

Term
Clinical research, phase 2
Definition
Tested on smaller patient population, those who have the condition the drug is designed to treat. Determines the success rate of the drug.
Term
Clinical reserach, phase 3
Definition
Larger patient population, insures statistical success, additional information on proper dosage and safety. Entire research phase may require 2 to 10 years, everage is 5 years.
Term
New Drug Application
Definition
a formal request to the FDA to market a new drug for human use
Term
Postmarketing Surveillance
Definition
the 4th phase when the manufacturer decides to market the medicine, new drug is monitered carefully
Term
MedWatch
Definition
health care practitioners are required to report adverse effects of drugs to MedWatch
Term
Teratogens
Definition
drugs taken during pregnancy that cause abnormal development of birth defects
Term
Receptors
Definition

specific sites which drugs form chemical bonds with in the body

 

drug -> receptor

key -> lock

Term
Agonists
Definition
Drugs that interact with a receptor to stimulate a response
Term
Antagonist
Definition
Drugs that attach to a receptor but do not stimulate  a response
Term
Partial agonists
Definition
Drugs that interact with a receptor to stimulate a response but inhibits other responses
Term
ADME (drug stages)
Definition

The 5 stages drugs go through:

liberation, absorption, distribution, metabolism, and excretion (pharmocokinetics)

Term
Enteral Route
Definition
drug is administered directly into GI (gastrointestinal) tract by oral, rectal, or nasogastric route
Term
Parenteral Route
Definition
Bypasses GI tract via using subcutaneous (subcut), intramuscular (IM), or intravenous (IV) injection
Term
Percutaneous Route
Definition
Includes inhalation, sublingual (under the tongue), or topical (on the skin)
Term
Liberation
Definition

dosage form being used, the pharmaceutic effect

(enteral, parenteral, percutaneous)

Term
Absorption
Definition
process whereby a drug is transferred from its site of entry into the body to the circulating fluids of the body
Term
Distribution
Definition
the ways in which drugs are transported throughout the body by the ciruclating blood fluids to receptors, metabolism, and excretion.
Term
Metabolism
Definition
also called biotransformation. It is the process by whereby the body inactivates the drug.
Term
Excretion
Definition
Eliminates drug metabolites and sometimes the active drug itself. Kidneys are a major organ of drug excretion. 
Term
Half-life
Definition
the amount of time required for 50% of the drug to be eliminated from the body
Term
Onset of action
Definition
concentration of drug at the site of action is sufficient to start a physiologic response
Term
Peak action
Definition
that time at which the drug reaches the highest concentration on the target receptors
Term
Duration of action
Definition
how long the drug has a pharmacologic effect
Term
Drug blood level
Definition

Blood sample drawn to determine the amount of drug present

 

if the blood level is low, the dosage must be increased

 

if the level is too high, the dosage must be decreased

Term
desired action
Definition
when a drug enters a patient and is absorbed and distributed
Term
side effects, adverse effects
Definition
when a drug affects more than one body system, sever side effects known as toxicity
Term
ADRs and ADEs
Definition

Adverse drug reaction - "right drug, right dose, right patient, bad effect"

Adverse drug events - "injury resluting from medical intervention related to a drug"

Term
Idiosyncratic reaction
Definition
when something unusual or abnormal happens when the drug is first administered
Term
Urticaria or hives
Definition
allergic response to drug - raised, irregularly shaped patches on the skin and severe itching
Term
Carcinogenicity
Definition
ability of a drug to induce living cells to mutate and become cancerous
Term
Tolerance
Definition
when a person begins to require a higher dosage to produce the same effects that a lower doage once provided
Term
Drug interaction
Definition

1. agents that, when combined, increase the actions of one or both drugs

2. agents that, when combined, decrease the effectiveness of one or both drugs

Term
Additive effect
Definition
two drugs with similar actions are taken for doubled effect
Term
Synergistic effect
Definition
combined effort of two drugs is greater than the sum of each drug given alone
Term
Antagonistic effect
Definition
one drug interferes with the action of another
Term
Displacement 
Definition
the displacement of the first drug by a second drug increases the activity of the first drug
Term
Interference
Definition
the first drug inhibits the metabolism or exrecetion of the second drug, causing increased activity of the second drug
Term
Incomaptibility
Definition
first drug is chemically incompatibile with the second drug, causing deterioration. Incompatiblie drugs shoulds not be mixed together.
