Summary
Ropivacaine is metabolized largely by CYP1A2, and ciprofloxacin can reduce its clearance. This may raise plasma ropivacaine levels, especially with prolonged infusion, increasing the risk of systemic local anesthetic toxicity.
What this interaction means in plain words
Ciprofloxacin and Ropivacaine can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Ciprofloxacin belongs to Anti Bacterial; Ropivacaine belongs to Central Nervous System.
Why it happens
Ciprofloxacin inhibits CYP1A2-mediated metabolism of ropivacaine.
What to do
Use the lowest effective ropivacaine dose and be cautious with continuous infusions. Monitor for neurologic and cardiac signs of local anesthetic toxicity.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
