Of the five basic medical uses for drugs, antibiotics are an example of curative drugs (agents used for the killing or removal of the causative agent of a disease). An immunizing agent is an example of a preventive or prophylactic drug, which is one used to stave off or abate the severity of a disease. Another medical use for drugs is in the treatment of a condition to provide symptomatic relief; this is known as therapeutic . Insulin and hormones are examples of the medical use of drugs known as replacement drugs. A fifth basic medical use of drugs is in conjunction with radiology and allows providers to pinpoint the location of diseases’ manifestations. This usage is known as diagnostic . The knowledge of the names of drugs is as essential to the medical assistant as the knowledge of basic uses for drugs. The majority of drugs have three types of names. The generic name is the drug’s official name assigned by the U.S. Adopted Names Council.Aspirin is an example of this type of name. The drug’s chemical name describes its molecular structure and identification of its chemical structure. Acetylsalicylic acid is an example of this type of name. Ecotrin is an example of a trade or brand name, which is registered by the U.S. Patent Office and approved for usage by the U.S. Food and Drug Administration. Medical assistants must also have a comprehensive understanding of the five basic sources of drugs. The source of digitalis, the dried leaf of a foxglove plant, is an example of a plant source. Insulin, a hormone derived from the pancreas of cows and hogs, is an example of a drug derived from an animal source. Drugs that are artificially prepared in pharmaceutical laboratories are known as synthetic drugs. Syn- thetically prepared sulfur, used in pharmaceutical products (such as certain bacteriostatic drugs), is an example of a drug derived from a mineral source. One of the latest sources for drugs has been provided by genetic engineering. Using a technique called gene splicing , scientists are able to create hybrid forms of life that can treat certain diseases; interferon for cancer treatment is an example of this process. 03047_sg_ch35_ptg01_hr_369_380.indd 371 DESIGN SERVICES OF 30/05/13 3:03 PM # 110592 Cust: Cengage Au: Lindh Pg.

Under federal law, providers who prescribe, administer, or dispense controlled substances must register with the DEA and renew their registration as required by state law. Describe the five schedules of classification for controlled substances and give an example for each. Schedule I specifies drugs that have a high potential for abuse and are not accepted for medical use within the United States: LSD, heroin. Schedule II includes drugs that have a high abuse potential and do have an accepted medical use within the United States: amphetamines and cocaine. Schedule III drugs have a low-to-moderate potential for physical dependence, yet have a high potential for psychological dependency: barbiturates and vari- ous drug combinations containing codeine and paregoric. Schedule IV drugs include drugs that when missed or abused can lead to limited physical or psychological dependency: chloral hydrate and diazepam. Schedule V drugs have the lowest potential for abuse of controlled substances: Lomotil and Donnagel. 2. For each of the following, identify whether the drug involved is an OTC medication (OTC) or a prescribed medication (PM). What patient guidelines for proper use are illustrated in each example? OTC A. Nora Fowler insists that Dr. Winston Lewis cannot help her rheumatoid arthritis and that simple ibuprofen is all she needs. Nora buys bulk generic bottles of ibuprofen at the drugstore for her rheumatoid arthritis and takes as many as she needs to help ease the painful inflammation in her joints and tissues. The patient is using an OTC drug instead of seeking appropriate medical care. Because the safe maximum dose is not effective for her, she takes too much ibuprofen to relieve the pain of her arthritis and risks negative side effects associated with misuse of the drug. PM B. When Jim Marshall experiences extreme stress while finishing the architectural designs for a new office building in the community, his girlfriend offers him a tablet or two of lorazepam, a benzodiazepine drug used to treat anxiety and insomnia. “Here, Dr. King gave me these, and they work great,” she says. “You can’t drive when you take this stuff, though. Oh, and these pills are about 2 years old, but I’m sure they’ll still work fine.” The patient should not take any medication prescribed for another person. All warning labels on medication containers should be heeded. Unused medication should be discarded properly, and no medication should be used without checking the expiration date. OTC C. At the slightest sniffle or sneeze, Lenore McDonell takes the strongest multisymptom cold medication she can find. Her philosophy is: “I might as well knock it out of my system.” Many OTC medications have several active ingredients, which may prove to be undesired or un- necessary to properly treat the condition. PM D. Abigail Johnson hates taking so many medications. So every now and then, when she feels especially good, Abigail just decides to stop taking the antihypertensive drug that is part of Dr. Elizabeth King’s treatment plan to control Abigail’s high blood pressure. On a bad day, she’ll take an extra pill. The provider should be consulted before stopping any prescribed medication. Sudden cessation of the antihypertensive medication could cause Abigail’s blood pressure to rise dangerously.
