The patient is scheduled to receive a medication that is an enzyme inducer of the P450 system. What best describes the effect of this medication on the patient?
1. In time, the patient will experience no effect from other medications.
2. In time, the patient will experience increased effects from other medications.
3. In time, the patient will experience a reduced effect from this medication.
4. In time, the patient will experience an increased effect from this medication.
Correct Answer: 3
Rationale: An enzyme inducer will increase the rate of its own metabolism, thereby reducing its effectiveness. An enzyme inhibitor will result in an increased effect of this medication. An enzyme inhibitor will result in an increased effect from other medications. The patient will experience a reduced effect from other medications, not an absence of effect.
