Question | Answer |
---|---|
absorption rate | how quickly a drug gets into the tissue to produce a therapeutic effect |
administration of medication | Providing one dose of a medication to an individual |
analgesia | A conscious state in which normal pain is not perceived, such as a numbing or sedativeeffect |
antacid | an agent that neutralizes stomach acid |
antiseptic | a substance that inhibits the growth of infectious agents. |
antibiotic | a soluble substance derived from a mold or bacterium that inhibits the growth of other micro-organisms. |
astringent | An agent that causes contraction of the tissues, arrest of secretion, or control of bleeding |
bioavailability | The amount of the drug's concentration when it reaches the target site within a certain time frame. |
antipyretic | a medication used to reduce a fever |
counterirritant | a substance causing irritation of superficial sensory nerves to reduce pain transmission from another underlying irritation |
drug dispensing | Providing more than one individual dose to a person |
antihistamine | A medication used to counteract the effects of histamine; one that relieves the symptoms of an allergic reaction |
drug interaction | The ability of one drug to alter the effects of another drug; it may either intensify (synergistic action) or reduce (inhibit) the effects of the other drug |
drug metabolism | The enzymatic alteration of a drug's structure whereby the original drug is broken down into metabolites |
enteric coated | Drugs covered by acid-resistant materials (e.g., fatty acids, waxes, and shellac) that protect the drug from the acid and pepsin in the stomach |
first-pass effect | Drug metabolism that takes place first in the liver via hepatic enzymes |
half life | the period during which an agent decreases to half its original strength. The longer the half-life of an agent, the slower it leaves the body |
heparin | an anticoagulant that is a component of various tissues and mast cells |
histamine | a powerful stimulant of gastric secretion, constrictor of bronchial smooth muscle, and vasodilator (capillaries and arterioles) that causes a fall in blood pressure |
minimum effective concentration | the minimum concentration of a drug that must be present for that drug to be effective |
rate of dissolution | a condition by which the more rapidly a drug dissolves, the faster the onset of its effects will be |
salicylates | any salt of salicylic acid; used in aspirin |
steroids | a large family of chemical substances, including endocrine secretions and hormones |
therapeutic drugs | prescription or over-the-counter medications used to treat an injury or illness |
therapeutic range | the range between the minimum effective concentration and toxic concentration |
toxic concentration | concentration of drug levels in the blood plasma that are too high and, therefore, increase the risk of toxic effects |
vehicles | substances combined with medications that use enteral routes to facilitate entry into the body |
