| Term | Definition |
|---|---|
| Absorption | The process by which a drug is taken into the body and moves from the site of administration into the blood. |
| Adverse effects | Are undesired, potentially harmful side effects of drugs. They can include nausea and vomiting, drug toxicity, hypersensitivity, and unusual reactions. |
| Agonist | Are drugs that bind to or have an attraction for a receptor and cause a particular response. |
| Antagonist | Drugs that bind to a receptor and prevent a response. |
| Bioavailability | Indicates the degree to which the drug molecule reaches the site of action to exert its effects. |
| Biotechnology | Concepts of genetic engineering and recombinant DNA technology. |
| Biotransformation | the chemical composition of a drug is changed by a process called metabolism. |
| Bolus | Drugs that are given all at once. |
| Contraindication | Reasons against giving a particular drug |
| Distribution | The process in which drug molecules eventually diffuse out of the blood-stream to the site of action. |
| Duration | The time between onset and disappearance of drug effects |
| Emulsion | Type of liquid medication form and can be either water in oil or oil in water, depending on the medication’s solubility. |
| Enteral | Indicates that the medication is taken into the gastrointestinal tract, primarily by mouth. |
| Excretion | Medications taken into the body are eliminated in the process |
| Hypersensitivity | An adverse effect resulting from previous exposure to the drug or a similar drug. |
| Idiosyncratic effect | Type of adverse effect that is thought to occur in people with some genetic abnormality, causing either an excessive or an inadequate response to a drug. |
| Indication | The reason or purpose for giving a medication. |
| Local effect | Some topical agents work at the site of application. |
| Onset | The time between administration of a drug and the first appearance of effects |
| Parenteral | Any route other than the digestive tract, the most common of which are subcutaneous, intramuscular, and intravenous. |
| Pharmacodynamics | The study of how drugs exert their effects on the body, at both the molecular and physiological levels. |
| Pharmacokinetics | Focuses on how the body processes drugs. |
| Plasma protein binding | Drug molecules that bind to proteins contained in plasma |
| Reconstituted | Mixed with a liquid |
| Side effect | A predictable but unintended effect of a drug. |
| Solubility | Ability to be dissolved |
| Solution | A mixture of drug particles |
| Suspension | A mixture of drug particles fully dissolved in a liquid medium |
| Synergist | A drug that enhances the effect of another drug |
| Systemic effect | Medications that exert throughout the entire body |
| Topical | Applied to the skin surface or a mucous membrane-lined cavity. |
| Controlled substances | High abuse potential drug |
| Narcotics | Is a controlled substance because they can be addictive and potentially abused |
| DEA | Drug Enforcement Administration |
| FDA | Food and Drug Administration |
| The Joint Commission | The predominant standards-setting organization, and facilities that obtain its accreditation demonstrate their commitment to meeting certain performance standards. |
| OTC | over-the-counter |
| PDR | Physicians’ Desk Reference |
| USP-NF | United States Pharmacopeia and National Formulary |
