1. Packaging of a drug is usually not considered to be part of compounding of
a dosage form. - ANSWER False
2. By definition, solutions are homogenous liquid mixtures in which the solute
is dispersed throughout the solvent in molecule-sized particles - ANSWER
True
3. Hydrogen bonding lS the main mechanism of water to dissolve alcohols. -
ANSWER True
4. Coca butter α melts at 23°C; Coca butter β melts at 35°C; therefore, Coca
butter α has a smaller aqueous solubility than Coca butter β. - ANSWER
False
5. For non-ionized drug molecules, the higher the LogP value of a drug, the
greater the lipid membrane permeability of the drug. - ANSWER True
, 6. The weak bases ammonia and morphine have pKb values of 4.76 and 6.13,
respectively. Therefore, ammonia is a stronger base than morphine. -
ANSWER True
7. Dissolution rate of a weak acid drug is expected to increase in a solution
with low pH compared to a solution with high pH - ANSWER False
8. By definition, buffers are made with a strong base, strong acid and their
salts - ANSWER False
9. Weak electrolytes are defined as incompletely ionized in pH range 0-14. -
ANSWER True
10. The buffer capacity depends on two factors: concentration ratio of the salt
to the acid or base; total buffer concentration. - ANSWER True
11. A 1.9% solution of boric acid is physically iso-osmotic (containing same
number of particles) with blood, and therefore will maintain isotonic with
blood. - ANSWER False
12. The importance of using isotonic solutions is to assure that there is no
tissue damage, pain or discomfort when the formulation is administered -
ANSWER True
13. Osmosis across a semipermeable membrane is dependent on the number
and nature of particles that are separated by the membrane. - ANSWER
False
