20. A 45-year-old female shop assistant is treated for heartburn
with omeprazole. She notes that the effect of a dose of
omeprazole lasts much longer than that of a dose of the
antacid drug calcium carbonate she had previously taken. The
active metabolite of omeprazole binds covalently and
irreversibly to a molecular structure involved in releasing
protons into the gastric juice. Drugs that modify their target
structures through this mechanism are called suicide
substrates. orphan drugs. protein drugs. competitive
antagonists.
enantiomers. - CORRECT ANSWER - A
21. A 36-year-old male has been diagnosed with chronic
myeloid leukemia. His oncologist discusses treatment options
with him. The patient is glad to hear that novel anticancer drugs
used to treat chronic myeloid leukemia have a much better risk-
benefit ratio than older ones, due to their improved selectivity. A
major determinant for the selectivity of a given drug is A) its
target receptor ligand affinity.
