| Question | Answer |
|---|---|
| absorption | The movement of a drug from the dosage formulation to the blood. |
| active transport | The movement of drugs from an area of lower concentration to an area of higher concentration. |
| agonists | Drugs that activate receptors to accelerate or slow normal cellular function. |
| antagonists | Drugs that bind with receptors but do not activate them. |
| bioavailability | The relative amount of an administered dose that reaches the general circulation and the rate at which this occurs. |
| bioequivalency | The comparison of bioavailability between two dosage forms. |
| biopharmaceutics | The study of the factors associated with drug products and physiological processes and the resulting systemic concentrations of drugs. |
| duration of action | The time the drug concentration is above the MEC. |
| enzyme | A complex protein that catalyzes chemical reactions. |
| enzyme induction | The increase in hepatic enzyme activity that results in greater metabolism of drugs. |
| enzyme inhibition | The decrease in hepatic enzyme activity that results in reduced metabolism of drugs. |
| first-pass metabolism | The substantial degradation of an orally administered drug caused by enzyme metabolism in the liver before the drug reaches the systemic circulation. |
| gastric emptying time | The time a drug will stay in the stomach before it is emptied into the small intestine. |
| hydrophilic | Capable of associating with or absorbing water. |
| hydrophobic | Water repelling; cannot associate with water. |
| lipoidal | Fat-like substance. |
| metabolite | The substance resulting from the body's transformation of an administered drug. |
| minimum effective concentration (MEC) | The blood concentration needed for a drug to produce a response. |
| minimum toxic concentration (MTC) | The upper limit of the therapeutic window. |
| nephron | The functional unit of the kidney. |
| onset of action | The time MEC is reached and the response occurs. |
| passive diffusion | The movement of drugs from an area of higher concentration to lower concentration. |
| pharmaceutical alternative | Drug products that contain the same active ingredient but not necessarily in the same salt form, amount, or dosage form. |
| pharmaceutical equivalent | Drug products that contain identical amounts of the same active ingredient in the same dosage form. |
| protein binding | The attachment of a drug molecule to a protein, effectively making the drug inactive. |
| receptor | The cellular material which interacts with the drug. |
| selective (action) | The characteristic of a drug that makes its action specific to certain receptors. |
| site of action | The location where an administered drug produces an effect. |
| therapeutic equivalent | Pharmaceutical equivalents that produce the same effects in patients. |
| therapeutic window | A drug's blood concentration ranges between its MEC and MTC. |
