MULTIPLE CHOICE
1. Knowledge of pharmacology aids the dental professional in
a. obtaining a patient’s health history.
b. administering drugs in the office.
c. handling emergency situations.
d. selection of a nonprescription medication.
e. All of the above.
CORRECT ANSWER: E
All of the choices are true. Because many of our patients are being treated with drugs, knowledge of
pharmacology helps in understanding and interpreting patients’ responses to health history questions.
Knowledge of the therapeutic and adverse effects of medications obviously helps in their proper administration
in the office. Emergency situations may be caused by drugs or treated by drugs; thus, knowledge of
pharmacology is of great help, especially because a rapid response is sometimes required. A clear
understanding of the concepts of drug action, drug handling by the body, and drug interactions will allow the
dental practitioner to make proper judgments and grasp the concepts relevant to new drug therapies on the
market.

cause adverse effects and interact with different drugs.

4. Which type of drug name usually begins with a lowercase letter?
a. Brand name
b. Code name
c. Generic name
d. Trade name
CORRECT ANSWER: C
Before any drug is marketed, it is given a generic name that becomes the ―official‖ name of the drug. Each
drug is assigned only one generic name selected by the U.S. Adopted Name Council, and the name is not
capitalized. The brand name is equivalent to the trade name and is capitalized. Although the brand name is
technically the name of the company marketing the product, this term is often used interchangeably with the
trade name. The code name is the initial term used within a pharmaceutical company to refer to a drug while it
is undergoing investigation and is often a combination of capital letters and numbers, the letters representing
an abbreviation of the company name.

d. Federal Patent Office.
CORRECT ANSWER: C
Each drug is assigned only one generic name (e.g., ibuprofen). It is selected by the U.S. Adopted Name
Council. The generic name is not selected by the FDA or the Federal Patent Office. The pharmaceutical
company manufacturing the drug clearly has an influence on the generic name given its drug, but the final
decision is not the company’s.

6. Which of the following is true concerning generic and trade names of drugs?
a. A drug may only have one generic name and one trade name.
b. A drug may only have one generic name, but it may have several trade names.
c. A drug may have several generic names, but it may only have one trade name.
d. A drug may have several generic names and several trade names.
CORRECT ANSWER: B
Each drug has only one generic name but may have several trade names. For each drug, there is only one
generic name. It is not capitalized, and it becomes the ―official‖ name of the drug. The pharmaceutical
company discovering the drug gives the drug a trade name. The trade name is protected by the Federal Patent
Law for 20 years from the earliest claimed filing date, plus patent term extensions. Although the brand name is
technically the name of the company marketing the product, it is often used interchangeably with the trade
name.

7. Two drugs that are found to be chemically equivalent, but not biologically equivalent or therapeutically
equivalent are said to differ in
a. potency.
b. efficacy.
c. bioavailability.
d. therapeutic index.
CORRECT ANSWER: C
A preparation can be chemically equivalent yet not biologically or therapeutically equivalent. These products
are said to differ in their bioavailability. The potency of a drug is a function of the amount of drug required to
TB
produce an effect. The efficacy is the maximum intensity of effect or response that can be produced by a drug.
The therapeutic index is the ratio of the lethal dose for 50% of the experimental animals divided by the
