      Drug Name Probenecid Benzylpenicillin (potassium)
      Mechanism Competitive inhibition of renal tubular secretion of penicillins Penicillins
      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 Benzylpenicillin (potassium) caused by Probenecid mediated competitive inhibition of renal tubular secretion
