Terms (Calculation of Doses) Flashcards
(30 cards)
quantitative amount administered or taken by a patient for the intended medicinal effect
dose
the amount taken at one time
single dose
the amount taken during the course of therapy
daily dose/total dose
the schedule of dosing (ex. QID for 10 days)
dosage regimen
the amount that ordinarily produces the medicinal effect intended in the adult patient
usual adult dose
similarly defined for the infant or child patient
usual pediatric dose
the quantitative amounts of the drug that may be prescribed within the guidelines of usual medical practice
usual dosage range
the amount that produces the desired intensity of effect in 50% of the individuals tested
median effective dose
the amount that produces toxic effects in 50% of the individuals tested
median toxic dose
or priming dose, a larger than usual initial dose may be required to achieve the desired blood drug level
loading dose
the minimum concentration to produce the drug’s desired effects in a patient
median effective concentration (mec)
the concentration that produces dose-related toxic effects
minimum toxic concentration (mtc)
referred to as the primary drug treatment
monotherapy
additional to or supportive of a different primary treatment
adjunctive therapy
administered to protect the patient from contracting a specific disease (ex. vaccines)
prophylactic doses
contain pharmaceutical ingredients which provide the physical features, stability requirements, and aesthetic characteristics desired for optimal therapeutic effects
dosage forms
examples of pharmaceutical ingredients
solvents, vehicles, preservatives, flavorants, fillers
number of doses calculation
number of doses = total quantity/size of dose
size of dose calculation
size of dose = total quantity/number of doses
total quantity calculation
total quantity = number of doses x size of dose
In using the equation, the total quantity and the size of dose must be
in the same unit of measure.
the administration of doses that are much smaller than the usual dose of a drug
*Use of Aspirin in 81-mg amounts (rather than the usual dose of 325 mg) to lower the risk of heart attack and clot-related stroke.
low-dose therapy
the administration of doses that are much larger than the usual dose of a drug
*Commonly associated with the chemotherapeutic treatment of cancer
high-dose therapy
dosing options:
low-dose therapy and high-dose therapy
