| Question | Answer |
|---|---|
| drug form | same as drug preparation |
| transdermal | patch providing constant, even flow of drug over a period of time |
| cap | capsule |
| IM | intramuscular |
| IV | intravenous |
| IVPB | intravenous piggyback |
| route of delivery | most suited means of absorption for intended use |
| subq | subcutaneous |
| R | rectal |
| PO | oral, by mouth |
| tab | tablet |
| susp | suspension |
| supp | suppository |
| gtt | drop |
| elix | elixir |
| parenteral | any route not involving the GI tract |
| capsule | drug contained within a gel type container |
| enteric coated | special coating that resists disintegration by gastric juices |
| time release | delivers a dose of drugs over an extended period of time |
| tablet | disk of the compressed drug |
| lozenge | often have a soothing effect on the throat |
| suspension | liquid form that must be shaken well; the drug is not evenly dissolved in the liquid |
| emulsion | liquid form that contains fats and oils in water |
| elixir | contains an alcohol base |
| syrup | sweetened liquid, common for giving to children |
| solution | liquid in which the drug is evenly dissolved, appearance is clear |
| suppository | is inserted into the rectum, melts at body temperature |
| enema solution | drug is suspended in a solution solely for enema purpose |
| injectable drug forms | solution and powder |
| intravaneous | injected directly into a vein; absorption is immediate |
| intramuscular | injected into a muscle; absorption is rapid |
| subcutaneous | injected into the fatty tissue below the skin, slower absorption |
| intradermal | injected just beneath the skin, as in allegy skin testing |
| epidural | injected into a catheter that has been placed in the spinal canal |
| intracardiac | injected directly into the heart |
| intraspinal | injected directly into the subarachnoid space, containing cerebrospinal fluid |
| intracapsular | injected into the capsule of a joint, to reduce inflammation |
| mucosal drug forms | eye, ear, nose drops; eye ointment; vaginal cremes; rectal and vaginal suppositories; douche solutions; buccal tablet; sublingual tablet |
| dermal application drug forms | creams, ointments, lotion, liniment, dermal patch |
| inhalable drug forms | spray, mist, gas |
| bolus | aka IV push; whole amount of the drug is injected in a short period of time |
| IV infusion | injected into the IV bag, aka IV drip |
| intraperitoneal | drugs administered into the peritoneal cavity, used for chemotherapy or dialysis fluid |
| intrathecal | used to administer drugs within the meninges around the spinal cord |
| intra-arterial | used to administer chemotherapy directly into the area of cancer, can be worn externally |
| pharmacokinetics | the study of how drugs move through the body in the processes of absorption, distribution, metabolism, excretion |
| barriers to drug distribution | blood-brain barrier; placental barrier; selective distribution |
| excretion or elimnation | respiration, perspiration, urination, defecation |
| half-life | the time it takes for half of the drug to be eliminated from the body; determines how frequently a drug should be taken |
| agonist drugs | when a drug displays an affinity or attraction for a receptor and stimulates it; drug that mimics body function |
| antagonist drugs | a drug that has an affinity for a receptor but displays no intrinsic activity |
| synergist | one drug potentiates another drug |
| receptor site | where drugs will attach, the better the fit of the drug the better the expected response |
| competitive antagonist | competes with the agonist for receptor sites, larger doses of the agonist can overcome the antagonist effects |
| noncompetitive antagonist | binds to the receptor site and blocks the effects of the agonist, larger doses of the agonist can't reverse its action |
| types of receptors | adrenergic, cholineric, H1 and H2 |
| contraindication | absolutely should not be given |
| idiopathic | unknown |
| paradoxical | opposite of the expected result |
| idiosyncrasy | unique, unusual response for a drug |
