Unit 1, Chapter 2 Flashcards
What is bioavailability?
Percentage of the drug dosage that is absorbed.
What is drug absorption?
Entrance of a drug into the bloodstream from its site of administration.
What is drug addiction?
Condition of drug abuse and drug dependence that is characterized by compulsive drug behavior.
What is drug dependence?
Condition of reliance on the use of a particular drug, characterized as physical and/or psychological dependence.
What is drug distribution?
Passage of a drug from the blood to the tissues and organs of the body.
What is drug excretion?
Elimination of the drug from the body.
What is drug metabolism?
The enzymatic biotransformation of a drug into metabolites.
What is the drug microsomal metabolizing system (DMMS)?
Group of enzymes located primarily in the liver that function to metabolize (biotransformation) drugs.
What is drug tolerance?
Decreased drug effect occurring after repeated drug administration.
What is enzyme induction?
Increase in the amount of drug-metabolizing enzymes after repeated administration of certain drugs.
What is enzyme inhibition?
Inhibition of drug-metabolizing enzymes by certain drugs.
What is first-pass metabolism?
Drug metabolism that occurs in the intestines and liver during oral absorption of drugs into the systemic circulation.
What is half-life?
Time required for the body to reduce the amount of drug in the plasma by one-half.
What is individual variation?
Difference in the effects of drugs and drug dosages from one person to another.
What is intramuscular (IM) injection?
Route of drug administration; drug is injected into gluteal or deltoid muscles.
What is intravenous (IV) injection?
Route of drug administration; drug is injected directly into a vein.
What is a loading dose?
Initial drug dose administered to rapidly achieve therapeutic drug concentrations.
What is a maintenance dose?
Dose administered to maintain drug levels in blood in the therapeutic range.
What is oral administration?
Route of drug administration by way of the mouth through swallowing.
What is parenteral administration?
Route of drug administration that does not involve the gastrointestinal (GI) tract.
What is pharmacokinetics?
Describes the processes of drug absorption, drug distribution, drug metabolism, and drug excretion.
Synergism
Drugs working together for a better effect.
Antagonism
Drugs working against each other or counteracting each other’s effect.
Distribution
Movement of drug from bloodstream into a tissue or organ.
Lethal dose
Amount of drug that can cause death.
Allergic reaction
Signs include rash, itching, carticoria, and dyspnea.
Toxic dose
Amount of drug that can cause dangerous side effects.
Maintenance dose
Amount of drug required to keep drug level steady.
Metabolism
Breakdown of drug to an inactive state.
Idiosyncrasy
Unusual response to a drug, other than expected effect.
Tolerance
Decreased response after repeated use of a drug, increased dosage required for effect.
Dependence
Acquired need for a drug, with symptoms of withdrawal when discontinued.
Teratogenic
Effects on a fetus from maternal use of a drug.
Pharmacology
Study of drug therapy on the body.
Agonist
A drug that binds to a receptor to cause a desired effect.

Intramuscular
A tablet placed under the tongue
Sublingual
A tablet placed in the cheek pouch
Buccal

Pharmatherapeutics
There are four human phases that are “required” in the process of developing a new drug.
False
A chemical name is a precise name given to the drug based on it’s chemical structure.
True
The time-response curve determines potency of a drug.
False
The Food, Drug and Cosmetic Act of 1938 determined:
Drugs that enter the market must be safe.
This law provided grants to research companies to develop new drugs for diseases or conditions.
