Mechanism of Probenecid-Avibactam Interaction (Severity Level: Moderate)
Competitive inhibition of renal tubular secretion Click to Show/Hide Mechanism Graph
Drug Name		Probenecid				Avibactam
Mechanism		Competitive inhibition of renal tubular secretion of some cephalosporins				Cephalosporins
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 Avibactam caused by Probenecid mediated competitive inhibition of renal tubular secretion

Recommended Action
Management		Due to a lack of clinical data, concomitant use of avibactam with probenecid is not recommended.
