Chapter 1 Flashcards
adverse effects
drug effects that are not the desired therapeutic effects; may be unpleasant or even dangerous
brand name
trade name of approved drug; name given to a drug by pharmaceutical company that developed it
drugs
chemicals that are introduced into the body to bring about some sort of change
FDA
federal agency responsible for the regulation and enforcement of drug evaluation and distribution policies
generic name
the original designation that a drug is given when the drug company that developed it applies for the approval process
genetic engineering
process of altering DNA, usually bacteria, to produce a chemical to be used as a drug
orphan drugs
drugs that have been discovered but would not be profitable for a drug company to develop; usually drugs that would treat only a small number of people
OTC
deemed to be safe when used as directed; drugs are available w/o a prescription for self-treatment of a variety of complaints
pharmacology
the study of biological effects of chemicals
pharmacotherapeutics
clinical pharmacology–the branch of pharmacology that deals w/ drugs; chemicals that are used in medicine for the Tx, prevention, and Dx of disease in humans
phase I study
a pilot study of a potential drug done w/ a small number of selected, healthy human volunteers. most are done on men.
phase II study
a clinical study of a proposed drug by selected physicians using actual patients who have the disorder the drug is designed to treat; patients must provide informed consent
phase III study
use of proposed drug on a wide scale in the clinical setting w/ patients who have the disease the drug is thought to treat. patients are asked to keep a journal so prescribers can determine if the reported effects are from the disease or the drug
phase IV study
continual evaluation of a drug after it has been released for marketing. sometimes the effects are therapeutic and new discoveries are made.
preclinical trials
initial trial of a chemical thought to have therapeutic potential; uses laboratory animals, not human subjects. Done to determine if the chemicals have the presumed effects in living tissue, and evaluate adverse effects.
teratogenic
having adverse effects on the fetus (one reason some chemicals are discarded after preclinical trial)
Which branch of pharmacology uses drugs to treat, prevent, and diagnose diseases?
Pharmacotherapeutics
What is another name for pharmacotherapeutics?
Clinical pharmacology
What is the concern of clinical pharmacology?
The drug’s effects on the body and the body’s response to the drug.
What are the two different effects of drugs?
therapeutic and adverse
Why are animal products being used less often to replace human chemicals?
genetic engineering, synthetic preparations, are safer.
What is a nurse’s position regarding drug therapy?
ADMINISTERING drugs, ASSESSING the effects, INTERVENING to make the regimen more tolerable, provident patient TEACHING, and MONITORING the overall care plan to prevent medication errors. (All of this enhances the effectiveness of drug therapy.)
How do the changes in chemical structure benefit the drugs?
They are more potent, stable and less toxic. Genetic engineering alters bacteria to produce chemicals that are therapeutic and effective.
What is the synthetic version of the active ingredient in marijuana called?
Marinol. Helps prevent N&V in cancer patients w/o the adverse effects of smoking the leaves.
