What is the purpose for drug monitoring? | ID non-compliance; Ascertain effectiveness of dosage; verify therapeutic range; Maximize therapeutic benefit and minimize adverse toxic reaction |
The body sees drugs, etc as______. | foreign material/toxins |
List the four general processes of metabolism. | Absorption; Distribution; Metabolism; Excretion |
What are the 3 routes toxins/drugs are absorbed? | orally; rectally; parenterally (IV, IM) |
What is a metabolite? | By product of metabolism or digestion |
Which stage in the process of metabolism must the drug traverse the membrane when it reaches the tissue site? | Distribution |
How does the body interpret drugs? | Foreign material |
How are soluble and insoluble drugs excreted from the body? | Soluble drugs are excreted through the kidneys, and insoluble drugs must first be converted to soluble by the liver before it can be excreted by the kidneys. |
Why do neonates have little capacity to eliminate drugs? | immature liver and kidneys |
For children the dose is____the adult dose. | 2x; due to very active drug disposition (metabolism) |
In the elderly drug disposition is________. | Decreased |
Elderly have decreased drug disposition due to: | dec albumin 9carrier protein); dec metabolic rate; effects of disease |
How does pregnancy affect drug disposition? | Hormonal chnages; Increased fluid volume |
How does disease affect drug disposition? | hepatic function; cardiac capacity; renal function |
What is the admin data needed for drug testing? | PT name, SSN, DOB, sex; date and time of colection; date/time of last dose; amt of last dose; name of drug; PT diagnosis; |
Which is most important of the admin data? | Time |
What are the sample requirements in drug testing? | Non hemolyzed serum/ plasma |
What guidelines should you consider on collection? | trough, peak |
prior to dose, drug concentration lowest level | trough |
60 min after dose highest level of concentration | peak |
How do you store drugs? | Centrifuge samples; seperate serum/plasma from cells ASAP; most drugs/metabolites stable several days @ RT |
Detects wide variety of drugs? | TLC |
Better ID of drugs than TLC? | GC |
Further specificity & extreme sensativity. | MS |
Measure drugs simultaneously (slow) | HPLC |
Which methodology uses carrier gas to seperate compounds? | Gas Chromatography |
Which methodology id the method of choice? | EIA--uses enzyme |
