How are drugs categorized into pharmacologic classes? Correct
Answers according to their physiologic function (beta-
adrenergic blockers) and primary disease states treated
(anticonvulsants, antiinfectives)
How can drugs be injected? Correct Answers -intradermally
-subcutaneously

How can one accommodate a patient that cannot swallow or is
unwilling to swallow a tablet or capsule or someone with an
enteral feeding tube? Correct Answers capsules, powder, or
liquid contents can often be added to soft foods such as
applesauce or pudding, or dissolved in a beverage
granules contained in capsules are usually for extended drug
release and normally should not be crushed or chewed by the
patient. However, they can often be swallowed when sprinkled
on one of the soft foods.
How have dosage forms been developed to encourage patient
adherence with the medication regimen? Correct Answers
Extended-release tablets and capsules. They release the drug
molecules in the patients GI tract over a prolonged period of
time. This prolongs drug absorption and duration.
-opposite of immediate-release dosage forms which release the
drug immediately after dissolution in the GI tract
How is renal excretion accomplished? Correct Answers through
glomerular filtration, active tubular reabsorption, and active
tubular secretion
-free unbound water soluble drugs and metabolites go through
passive glomerular filtration.
-many substances present in the nephrons go through active
reabsorption and are taken back up into the systemic circulation
,and transported away from the kidney. body's attempt to retain
needed substances
How is the absorbed particles transported to the site of action?
Correct Answers blood or lymph
