Interactions between your drugs
nicotine fenofibrate
Applies to: Nicotrol Inhaler (nicotine), fenofibrate
MONITOR: Coadministration with fenofibrate may increase the plasma concentrations and risk of adverse effects of drugs that are substrates of CYP450 2C19, 2A6, and 2C9 isoenzymes. The proposed mechanism, based on in vitro data, is decreased clearance due to fenofibrate-mediated inhibition of CYP450 2C19, 2A6, and 2C9.
MANAGEMENT: Until more information is available, caution is advised if fenofibrate is used concomitantly with drugs that are substrates of CYP450 2C19, 2A6, or 2C9 isoenzymes, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring should be considered whenever fenofibrate is added to or withdrawn from therapy with these drugs. Patients should be monitored for the development of adverse effects.

One study (n=12) has reported that there was a significant interactive effect of caffeine and nicotine on subjective arousal such that nicotine decreased arousal only in the presence of caffeine. The exact mechanism of this interaction has not been specified. Further research is needed to examine the subjective and physiological interactions between caffeine and nicotine.
