      Drug Name Ciprofloxacin Probenecid
      Mechanism Quinolone Inhibition of the renal tubular secretion of quinolone
      Key Mechanism Factor 1
Factor Name Renal tubular secretion
Factor Description Renal tubular secretion allows selective transfer of substances from the blood around the capillaries into the renal tubules via filtrate. Drug excretion may be reduced when two drugs compete for renal tubular secretion.
      Mechanism Description
  • Decreased elimination of Ciprofloxacin caused by Probenecid mediated competitive inhibition of renal tubular secretion
