008. What does the term “bioavailability” mean?
a) Plasma protein binding degree of substance
b) Permeability through the brain-blood barrier
c) Fraction of an uncharged drug reaching the systemic circulation following any route administration
d) Amount of a substance in urine relative to the initial doze
009. The reasons determing bioavailability are:
a) Rheological parameters of blood

b) Oral
c) Intravenous
d) Intramuscular
012. What is characteristic of the oral route?

d) The sterilization of medicinal forms is obligatory
013. Tick the feature of the sublingual route:
a) Pretty fast absorption
b) A drug is exposed to gastric secretion

d) A drug can be administrated in a variety of doses
014. Pick out the parenteral route of medicinal agent administration:
a) Rectal
b) Oral
