      Drug Name Probenecid Ofloxacin
      Mechanism Inhibition of the renal tubular secretion of quinolone 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 Ofloxacin caused by Probenecid mediated competitive inhibition of renal tubular secretion
