Chapter 23 questions
| Question | Answer |
|---|---|
| Study of how drugs produce their effect on their desired cell and how drugs are processed in the body | Pharmacodynamics |
| The location where the drug will exert its desired action | Site of action |
| Explains how a drug works and produces its desirable or undesirable effect | Mechanism of action |
| Location where the drug binds to the cell | Receptor site |
| Specific type of drug that produces a certain predicted actions | Agonist |
| Type of drug that does not produce or inhibits the desirable effect and blocks cell receptors | Antagonist |
| The degree to which a drug becomes available to tissues after administration | Bioavailability |
| Occurs when a person requires larger doses of a drug to achieve the same effect | Tolerance |
| The body’s response to a drug | Desired effect |
| Indicates that the body’s response to a drug is directly related to the amount taken | Dose response curve |
| The maximal response that the body has to a drug known as the | Ceiling |
| The measurement of strength of the drug that is required | Potency |
| The amount needed to achieve 50% of the maximal response | ED50 |
| Time required for plasma serum concentration levels to decrease by one half | Half life |
| Half life is written as | T1/2 |
| Length of time in which a drug will continue to have the same degree of effect is know as the | Time response curve |
| The process where the drug is moved from its site of administration into the bloodstream | Absorption |
| What drug bypasses absorption | Intravenous |
| When the dry is moved from the bloodstream to the tissues or receptors | Distribution |
| Movement of a substance across the cell membrane | Passive diffusion |
| Carrier proteins permit specific molecules from passing through certain parts of the cell | Facilitated diffusion |
| Cell engulfs the substance and permits the substance to enter the cell | Pinocytosis |
| The more lipid soluble the drug is the more ______ the drug will be absorbed into the body | Quickly |
| Time is takes the drug to be eliminated from the body | Clearance |
| Process where the drug effects the cell in the body by interacting with receptors can be compared to a _____ and ______ | Lock and key |
| You would use _____________ to find out how drugs are changed in the body from their original form to something the body can use | Pharmacokinetics |
| ________ binds directly to the cell membrane and is not absorbed by the body in any way | Metamucil |
| The______ of a drug governs it’s bioavailability | Absorption |
| Some drugs require immediate access to the body’s cells while others survive longer to be effective because of the ___________ of the drug is time restricted | Bioavailability |
| _______ _________ does not require the cell to expend energy | Facilitated diffusion |
| When a chemical binds with a ________ it’s stimulated to either produce or inhibit an action | Receptor |
| For an oral medication to be absorbed into the body it must go through the ____ _______ _______ which is completed the liver | First pass process |
| When serum concentration is less that 3% it is considered | To be removed from the body |
| Many problems related to drug drug interactions occur when antagonistic drug is added to.... | A number of other antagonistic drugs |
| Drug drug interactions may occur because _____________________ healthy people | Drug testing is never performed on |
| ____ _________ is more important because drugs that are eliminated more slowly than they are absorbed can cause interactions with other substances | Drug clearance |
