MULTIPLE CHOICE t
1. Knowledge of pharmacology aids the dental professional in t t t t t t t
a. obtaining a patient’s health history. t t t t
b. administering drugs in the office. t t t t
c. handling emergency situations. t t
d. selection of a nonprescription medication. t t t t
e. All of the above. t t t
ANS: E t
All of the choices are true. Because many of our patients are being treated with drugs, knowledge of
t t t t t t t t t t t t t t t t t
pharmacology helps in understanding and interpreting patients’ responses to health history questions.
t t t t t t t t t t t t
Knowledge of the therapeutic and adverse effects of medications obviously helps in their proper
t t t t t t t t t t t t t t
administration in the office. Emergency situations may be caused by drugs or treated by drugs; thus,
t t t t t t t t t t t t t t t t
knowledge of pharmacology is of great help, especially because a rapid response is sometimes
t t t t t t t t t t t t t t
required. A clear understanding of the concepts of drug action, drug handling by the body, and drug
t t t t t t t t t t t t t t t t t
interactions will allow the dental practitioner to make proper judgments and grasp the concepts relevant
t t t t t t t t t t t t t t t
to new drug therapies on the market.

2. Which of the following statements is true regarding planning appointments?
t t t t t t t t t
a. Whether or not patients are taking medication for systemic diseases is of little
t t t t t t t t t t t t
consequence in the dental office. t t t t
b. Asthmatic patients should have dental appointments in the morning. t t t t t t t t
c. Diabetic patients usually have fewer problems with a morning appointment
t t t t t t t t t
compared with afternoon appointments.
t t t t
d. Both B and C are true. t t t t t
ANS: D t
Asthmatic patients who experience dental anxiety should schedule their appointments when they are
t t t t t t t t t t t t
not rushed or under pressure early in the morning. Diabetic patients usually have relatively fewer
t t t t t t t t t t t t t t t
problems with a morning appointment. Patients taking medication for systemic diseases may require
t t t t t t t t t t t t t
special handling in the dental office.

,3. Nutritional or herbal supplements t t t
a. carry the U.S. Food and Drug Administration (FDA) approval for disease states.

d. will not interact with other drugs the patient may be taking.
t t t t t t t t t t
ANS: C t
Nutritional or herbal supplements are quite capable of causing adverse effects. The majority of
t t t t t t t t t t t t t
nutritional or herbal supplements do not carry FDA approval for treating disease states. These
t t t t t t t t t t t t t t
supplements are drugs and can cause adverse effects and interact with different drugs.

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

a. pharmaceutical company manufacturing it. t t t
b. Food and Drug Administration (FDA). t t t t
c. U.S. Adopted Name Council. t t t
d. Federal Patent Office. t t
ANS: C t
Each drug is assigned only one generic name (e.g., ibuprofen). It is selected by the U.S. Adopted Name
t t t t t t t t t t t t t t t t t
Council. The generic name is not selected by the FDA or the Federal Patent Office. The
t t t t t t t t t t t t t t t t
pharmaceutical company manufacturing the drug clearly has an influence on the generic name givenits
t t t t t t t t t t t t t t t
drug, but the final decision is not the company’s.

t t t t t t t t t t t t
a. A drug may only have one generic name and one trade name.
t t t t t t t t t t t
, b. A drug may only have one generic name, but it may have several trade names.
t t t t t t t t t t t t t t
c. A drug may have several generic names, but it may only have one trade name.
t t t t t t t t t t t t t t
d. A drug may have several generic names and several trade names.
t t t t t t t t t t
ANS: B t
Each drug has only one generic name but may have several trade names. For each drug, there is only one
t t t t t t t t t t t t t t t t t t t
generic name. It is not capitalized, and it becomes the “official” name of the drug. The pharmaceutical
t t t t t t t t t t t t t t t t t
company discovering the drug gives the drug a trade name. The trade name is protected by the Federal
t t t t t t t t t t t t t t t t t t
Patent Law for 20 years from the earliest claimed filing date, plus patent termextensions. Although the
t t t t t t t t t t t t t t t t t
brand name is technically the name of the company marketing the product, itis often used
t t t t t t t t t t t t t t t t
interchangeably with the trade name.

7. Two drugs that are found to be chemically equivalent, but not biologically equivalent or
t t t t t t t t t t t t t
therapeutically equivalent are said to differ in
t t t t t t t
a. potency.
b. efficacy.
c. bioavailability.
d. therapeutic index. t
ANS: C t
A preparation can be chemically equivalent yet not biologically or therapeutically equivalent. These
t t t t t t t t t t t t
products are said to differ in their bioavailability. The potency of a drug is a function of the amount of
t t t t t t t t t t t t t t t t t t t t
drug required to produce an effect. The efficacy is the maximum intensity of effect or response that can
t t t t t t t t t t t t t t t t t t
be produced by a drug. The therapeutic index is the ratio of the lethal dose for 50% of the experimental
t t t t t t t t t t t t t t t t t t t t
animals divided by the effective dose for 50% of the experimental animals. If the value of the
t t t t t t t t t t t t t t t t t
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
t t t t t t t t t t t t t t t t
same compound as a generic drug?
t t t t t t
a. 20 years t
b. 17 years t
c. 7 years t
d. 0 years t
ANS: D t
Once a drug patent expires, competing companies may immediately market the same compound in
t t t t t t t t t t t t t
generic form. The pharmaceutical company discovering the drug gives the drug a trade name. The
t t t t t t t t t t t t t t t
trade name is protected by the Federal Patent Law for 20 years from the earliest claimed filing date,
t t t t t t t t t t t t t t t t t t
plus the patent term extensions.
