Haveles: Applied Pharmacology for the Dental Hygienist, 8th Edition
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
ANS: 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.

c. Diabetic patients usually have fewer problems with a morning appointment
compared with afternoon appointments.
d. Both B and C are true.

they are not rushed or under pressure early in the morning. Diabetic patients usually have
relatively fewer problems with a morning appointment. Patients taking medication for
systemic diseases may require special handling in the dental office.

c. can cause adverse effects.

4. Which type of drug name usually begins with a lowercase letter?
a. Brand name
b. Code name
c. Generic name
d. Trade name
ANS: 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.

5. A drug’s generic name is selected by the
a. pharmaceutical company manufacturing it.
b. Food and Drug Administration (FDA).
c. U.S. Adopted Name Council.
d. Federal Patent Office.
ANS: 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.
, 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.
ANS: 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 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 effective dose for 50% of the
experimental animals. If the value of the therapeutic index is small, toxicity is more likely.

8. How many years must pass after a drug patent expires before other drug companies can
market the same compound as a generic drug?
a. 20 years
b. 17 years
c. 7 years
d. 0 years
ANS: D
Once a drug patent expires, competing companies may immediately market the same
compound in generic form. After 17 years, the patent of the original drug expires, and other
companies can market the same compound under a generic name.
