Part 1 (1-150) Flashcards
Agency in the US responsible for selecting
appropriate nonproprietary names for drugs
USAN
Official standards for individual drugs and
chemicals formulated into dosage forms are
published in the
USP/NF
Descriptions of the Federal Controlled
Substances Act, Approved Drug Products
with Therapeutic Equivalence Evaluations,
and USP/NF dispensing requirements may
be found in the
USP DI Volume III
Prescription drug descriptions expressed in a
layperson’s terms and useful as handouts for
patients may be photocopied from
US DI Volume II
Most frequently dispensed dosage form in
the US
Oral tablets
Classified as alternative medicine in the US EXCEPT
Allopathy
Alternative medical practice that stresses the
use of extremely small dose of drugs
Homeopathic medicine
Rate of disintegration for most commercial
tablets
sublingual -> uncoated -> coated
Tablet coatings used to mask the bitter tastes
of drugs
film, sugar
Diluent in tablet formulation EXCEPT
Magnesium stearate
Functions of lubricant in tablet formulation EXCEPT
improve tablet wetting in the stomach
Trademarked dosage form, enteric coated
Enseal
Sweetener that is widely employed in
chewable tablet formulation
Mannitol
Starch may be included in tablet formulation
Binder, disintegrant
Commission E Monographs are related to
Herbs
Specific drug is available both oral tablet and
liquid dosage forms
Liquid form absorbs faster

Lead
Solubility of a substance may be expressed
in several ways. When a quantitative
statement of solubility is given in USP, it is
generally expressed as
mL of solvent to dissolve 1g of solute
Although most drugs in pharmaceutical
dosage forms decompose following
first-order kinetics, exceptions are drugs
formulated in
Oral suspensions
Early sign of decomposing epinephrine
solution is the presence of
pink color
Process of grinding a substance to a very
fine powder
trituration
Term “impalpable” refers to a substance that
is
not perceptible to touch
Tartrazine may be included in drug products
coloring agent
Term “chiral” is related to a drug’s
stereoisomerism
Advantages of developing chiral forms of
drug
more direct action, economical
Different crystalline forms (polymorphs) of
the same drug exhibit different
melting point, solubility
Example of nonionic surfactant
sorbitan monopalmitate
Literature lists albuterol with two pKas of 9.3
and 10.3. Description most appropriate for
this drug
weak base
Patients following low sodium diets may
resort to the use of sodium-free salt
substitutes such as NoSalt. Major ingredient
in these products is
Potassium chloride
Potassium supplements are administered in EXCEPT
IV bolus
Statements true about fluorouracil EXCEPT
effective only when administered IV
Black box warning to a pharmacist
PI
Cautions found in drug product inserts in
order of least serious to most serious
Precaution, warning, CI
Comparison of individual amino acids
present in commercial amino acid injection
solution may be found in
Facts and comparison; Trissel’s handbook of injectable drugs
Release of an ingredient from packaging components into the actual product is best described by the term
leaching
Gauge numbers used to size hypodermic
needles reflect the needle
external diameter, cannula
Designation “winged” needles is most closely
associated with which type of injection
IV
Insulin preparations are usually administered
by
SC
Needle most suited for the administration of
insulin solutions
25G 5/8”
Term “venoclysis” is closely associated with
IV Infusion
Designation “mini bottles” refers to
partially filled parenteral with 50 to 150mL volume
Term “piggyback” is most commonly
associated with
Intermittent therapy
Refer to parenteral nutrition
TPN/TNA
Approximate maximum volume of fluid that
should be administered daily by IV infusion to
stabilized patient
4L
Although isotonicity is desirable for almost all
parenterals, it is particularly critical to
SC
Suspension is suitable for EXCEPT
IV
Most appropriate medical order requiring an
intravenous bolus injection
IVP
Even distribution of drug into the blood after
an IV bolus injection can be expected
within 4 mins
Quantities of all ingredients present in
parenteral solutions must be specified on the
label EXCEPT for
isotonicity, and pH adjustors
Usual expiration dating should be placed on
a parenteral admixture prepared in hospital
pharmacy
24hr
Parenteral solutions that are isotonic with
human RBCs have an osmolality of
approximately how many mOsm/L
300
Injectables isotonic with human RBCs
D5W; D 2.5/0.45NS
Osmotic pressure of 1 0.1-mol dextrose
solution will be approximately __ times that
of 0.1-mol sodium chloride solution
0.5
Parenteral solution considered most closely
approximate the extracellular fluid of the
human body
