A patient is taking drug A and drug B. The primary care NP notes increased effects of drug B. The NP should suspect that in this case drug A is a cytochrome P450 (CYP450) enzyme:

a. inhibitor.
b. substrate.
c. inducer.
d. metabolizer.


A
If drug A is a CYP450 enzyme inhibitor, it decreases the capacity of the enzyme to metabolize drug B, causing more of drug B to be available. A substrate is a drug acted on by the enzyme. If drug B is an enzyme inducer, it would cause increased metabolism of drug A.
