MULTIPLE CHOICE l




1. Knowledge of pharmacology aids the dental professional in l l l l l l l


a. obtaining a patient’s health history. l l l l


b. administering drugs in the office. l l l l


c. handling emergency situations. l l


d. selection of a nonprescription medication. l l l l


e. All of the above. l l l




ANS: E l


All of the choices are true. Because many of our patients are being treated with drugs, knowledge of pharma
l l l l l l l l l l l l l l l l l l


cology helps in understanding and interpreting patients’ responses to health history questions. Knowledge
l l l l l l l l l l l l l


of the therapeutic and adverse effects of medications obviously helps in their proper administration in the of
l l l l l l l l l l l l l l l l


fice. Emergency situations may be caused by drugs or treated by drugs; thus, knowledge of pharmacology is
l l l l l l l l l l l l l l l l


of great help, especially because a rapid response is sometimes required. A clear understanding of the conce
l l l l l l l l l l l l l l l l l


pts of drug action, drug handling by the body, and drug interactions will allow the dental practitioner to mak
l l l l l l l l l l l l l l l l l l


e proper judgments and grasp the concepts relevant to new drug therapies on the market.

2. Which of the following statements is true regarding planning appointments?
l l l l l l l l l


a. Whether or not patients are taking medication for systemic diseases is of little l l l l l l l l l l l l


consequence in the dental office. l l l l


b. Asthmatic patients should have dental appointments in the morning. l l l l l l l l


c. Diabetic patients usually have fewer problems with a morning appointment compa l l l l l l l l l l

d. Both B and C are true. l l l l l




ANS: D l


Asthmatic patients who experience dental anxiety should schedule their appointments when they are not rus
l l l l l l l l l l l l l l


hed or under pressure early in the morning. Diabetic patients usually have relatively fewer problems with a
l l l l l l l l l l l l l l l l l


morning appointment. Patients taking medication for systemic diseases may require special handling in the
l l l l l l l l l l l l l l


dental office. l

,3. Nutritional or herbal supplements l l l


a. carry the U.S. Food and Drug Administration (FDA) approval for disease states.
l l l l l l l l l l l


b. are not drugs. l l


c. can cause adverse effects. l l l


d. will not interact with other drugs the patient may be taking.
l l l l l l l l l l




ANS: C l


Nutritional or herbal supplements are quite capable of causing adverse effects. The majority of nutritional or h
l l l l l l l l l l l l l l l l


erbal supplements do not carry FDA approval for treating disease states. These supplements are drugs and ca
l l l l l l l l l l l l l l l l


n cause adverse effects and interact with different drugs.

4. Which type of drug name usually begins with a lowercase letter?
l l l l l l l l l l


a. Brand name l


b. Code name l


c. Generic name l


d. Trade name l




ANS: C l


Before any drug is marketed, it is given a generic name that becomes the ―official‖ name of the drug. Each dr
l l l l l l l l l l l l l l l l l l l l


ug is assigned only one generic name selected by the U.S. Adopted Name Council, and the name is not capita
l l l l l l l l l l l l l l l l l l l


lized. The brand name is equivalent to the trade name and is capitalized. Although the brand name is technic
l l l l l l l l l l l l l l l l l l


ally the name of the company marketing the product, this term is often used interchangeably with the trade na
l l l l l l l l l l l l l l l l l l


me. The code name is the initial term used within a pharmaceutical company to refer to a drug while it is unde
l l l l l l l l l l l l l l l l l l l l l


rgoing investigation and is often a combination of capital letters and numbers, the letters representing an ab
l l l l l l l l l l l l l l l l


breviation of the company name. l l l l

l l l l l l l


a. pharmaceutical company manufacturing it. l l l


b. Food and Drug Administration (FDA). l l l l


c. U.S. Adopted Name Council. l l l


d. Federal Patent Office. l l




ANS: C l


Each drug is assigned only one generic name (e.g., ibuprofen). It is selected by the U.S. Adopted Name Cou
l l l l l l l l l l l l l l l l l l


ncil. The generic name is not selected by the FDA or the Federal Patent Office. The pharmaceutical compan
l l l l l l l l l l l l l l l l l


y manufacturing the drug clearly has an influence on the generic name given its drug, but the final decision is
l l l l l l l l l l l l l l l l l l l l


not the company’s.

6. Which of the following is true concerning generic and trade names of drugs?
l l l l l l l l l l l l


a. A drug may only have one generic name and one trade name.
l l l l l l l l l l l

, b. A drug may only have one generic name, but it may have several trade names.
l l l l l l l l l l l l l l


c. A drug may have several generic names, but it may only have one trade name.
l l l l l l l l l l l l l l


d. A drug may have several generic names and several trade names.
l l l l l l l l l l




ANS: B l


Each drug has only one generic name but may have several trade names. For each drug, there is only one gene
l l l l l l l l l l l l l l l l l l l l


ric name. It is not capitalized, and it becomes the ―official‖ name of the drug. The pharmaceutical company d
l l l l l l l l l l l l l l l l l l


iscovering the drug gives the drug a trade name. The trade name is protected by the Federal Patent Law for 20
l l l l l l l l l l l l l l l l l l l l l


years from the earliest claimed filing date, plus patent term extensions. Although the brand name is technical
l l l l l l l l l l l l l l l l


ly 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 thera
l l l l l l l l l l l l l l


peutically equivalent are said to differ in l l l l l l


a. potency.
b. efficacy.
c. bioavailability.
d. therapeutic index. l




ANS: C l


A preparation can be chemically equivalent yet not biologically or therapeutically equivalent. These produ
l l l l l l l l l l l l l


cts are said to differ in their bioavailability. The potency of a drug is a function of the amount of drug required
l l l l l l l l l l l l l l l l l l l l l l


to produce an effect. The efficacy is the maximum intensity of effect or response that can be produced by a dr
l l l l l l l l l l l l l l l l l l l l


ug. The therapeutic index is the ratio of the lethal dose for 50% of the experimental animals divided by the eff
l l l l l l l l l l l l l l l l l l l l


ective dose for 50% of the experimental animals. If the value of the therapeutic index is small, toxicity is mor
l l l l l l l l l l l l l l l l l l l


e likely.

8. How many years must pass after a drug patent expires before other drug companies can market the same c
l l l l l l l l l l l l l l l l l l


ompound as a generic drug? l l l l


a. 20 years l


b. 17 years l


c. 7 years l


d. 0 years l




ANS: D l


Once a drug patent expires, competing companies may immediately market the same compound in generic
l l l l l l l l l l l l l l l


form. The pharmaceutical company discovering the drug gives the drug a trade name. The trade name is prot
l l l l l l l l l l l l l l l l l


ected by the Federal Patent Law for 20 years from the earliest claimed filing date, plus the patent term extensi
