caffeine ROPivacaine
Applies to: NoDoz Maximum Strength (caffeine) and ropivacaine
Ropivacaine serum concentrations may increase when given with drugs metabolized by the CYP450 isoenzyme 1A2. The theorized mechanism is via competitive inhibition. Information is only available from in-vitro studies. The clinical significance is unknown. Consider monitoring the patient more closely for prolonged or excessive ropivacaine effects if these agents are coadministered.

The effect of grapefruit juice on the pharmacologic activity of caffeine is controversial. One report suggests that grapefruit juice increases the effect of caffeine. The proposed mechanism is inhibition of cytochrome P-450 metabolism of caffeine. However, a well-conducted pharmacokinetic/pharmacodynamic study did not demonstrate this effect. The clinical significance of this potential interaction is unknown.
