a. obtaininga patient’s health history. ni ni ni ni




b. administeringdrugs in the office. ni ni ni ni




c. handlingemergencysituations. ni ni




d. selection ofa nonprescription medication. ni ni ni ni




e. All of the above. ni ni ni




ANS: n i E
All of the choices are true. Because many of our patients are being treated with drugs, knowledge of
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




pharmacologyhelpsin understandingand interpretingpatients’ responses to health historyquestions.
ni ni ni ni ni ni ni ni ni ni ni ni




Knowledge of the therapeutic and adverse effects of medications obviously helps in their proper
ni ni ni ni ni ni ni ni ni ni ni ni ni ni




administration in the office. Emergency situations may be caused by drugs or treated by drugs; thus,
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




knowledge of pharmacology is of great help, especially because a rapid response is sometimes required. A
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




clear understanding of the concepts of drug action, drug handling by the body, and drug interactions will
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




allow the dental practitioner to make proper judgments and grasp the concepts relevant to new drug
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




therapies on the market.

ANS: n i D
Asthmatic patients who experience dentalanxietyshould schedule their appointments when they are not
ni ni ni ni ni ni ni ni ni ni ni ni ni




rushed or under pressure early in the morning. Diabetic patients usually have relatively fewer problems
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni

Nutritional or herbal supplements are quite capableof causing adverse effects. The majorityof nutritional or ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




herbal supplements do not carry FDA approval for treating disease states. These supplements are drugs and
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




can cause adverse effects and interact with different drugs.

4. Whichtype of drug name usuallybegins with a lowercase letter?
ni ni ni ni ni ni ni ni ni ni




a. Brandname ni




b. Code name ni




c. Genericname ni




d. Tradename ni




ANS: n i C
Before anydrug is marketed, it is given a generic name that becomes the “official” name ofthe drug. Each
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




drug is assigned only one generic name selected by the U.S. Adopted Name Council, and the name is not
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




capitalized. The brand name is equivalent to the trade name and is capitalized. Although the brand name is
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




technicallythe name of the companymarketingthe product, this term is often used interchangeably with the
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




trade name. The code name is the initial term used within a pharmaceutical company to refer to a drug while
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




it is undergoing investigation and is often a combination of capital letters and numbers, the letters
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




representing an abbreviation of the company name.

a. pharmaceutical company manufacturingit. ni ni ni




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




c. U.S. Adopted Name Council. ni ni ni




d. Federal Patent Office. ni ni




ANS: n i C
Each drug is assigned only one generic name (e.g., ibuprofen). It is selected by the U.S. Adopted Name
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




Council. The generic name is not selected by the FDA or the Federal Patent Office. The pharmaceutical
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




companymanufacturingthe drug clearlyhas an influence on the generic name given its drug, but the final
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




decision is not the company’s.

6. Whichof the following is true concerninggeneric and tradenames of drugs?
ni ni ni ni ni ni ni ni ni ni ni ni




a. A drug mayonly have one generic name and one trade name.
ni ni ni ni ni ni ni ni ni ni ni

, b. A drug mayonly have one generic name, but it may have several trade names.
ni ni ni ni ni ni ni ni ni ni ni ni ni ni




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




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




ANS: n i B
Each drug has only one generic name but may have several trade names. For each drug, there is only one
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




generic name. It is not capitalized, and it becomes the “official” name of the drug. The pharmaceutical
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




company discovering the drug gives the drug a trade name. The trade name is protected bythe Federal Patent
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




Lawfor 20 years from the earliest claimed filing date, plus patent term extensions. Although the brand name
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




is technicallythe name of the companymarketingthe product, it is often used interchangeably with the trade
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




name.

7. Two drugs that are found to be chemicallyequivalent, but not biologicallyequivalent or
ni ni ni ni ni ni ni ni ni ni ni ni ni




ni therapeutically equivalent are said to differ in ni ni ni ni ni ni




a. potency.
b. efficacy.
c. bioavailability.
d. therapeuticindex. ni




ANS: n i C
A preparation can be chemically equivalent yet not biologically or therapeutically equivalent. These
ni ni ni ni ni ni ni ni ni ni ni ni




products are said to differ in their bioavailability. The potencyof a drug is a function of the amount of drug
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




required to produce an effect. The efficacy is the maximum intensity of effect or response that can be
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




produced by a drug. The therapeutic index is the ratio of the lethal dose for 50% of the experimental animals
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




divided by the effective dose for 50% of the experimental animals. If the value of the therapeutic index is
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni




small, toxicity is more likely.

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




compound as a generic drug?
ni ni ni ni ni




a. 20 years ni




b. 17 years ni




c. 7 years ni




d. 0 years ni




ANS: n i D
Once a drug patent expires, competing companies may immediately market the same compound in generic
ni ni ni ni ni ni ni ni ni ni ni ni ni ni




form. The pharmaceutical company discovering the drug gives the drug a trade name. The tradenameis
ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni ni
