Summary
Tobramycin is nephrotoxic and ototoxic, and carboplatin can also cause renal and hearing toxicity. Inhaled tobramycin has low systemic absorption, so the additive risk is smaller than with injectable aminoglycosides, but it may be higher with renal impairment. Cumulative injury could raise carboplatin exposure.
What this interaction means in plain words
Carboplatin and Tobramycin inhaled 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.
Why it happens
Additive nephrotoxicity and ototoxicity.
What to do
Monitor serum creatinine and review hearing symptoms during concurrent therapy. Consider tobramycin serum levels if renal function declines.
