Mechanism of Lisinopril-Probenecid Interaction (Severity Level: Minor)
Competitive inhibition of renal tubular secretion Click to Show/Hide Mechanism Graph
Drug Name		Lisinopril				Probenecid
Mechanism		ACE inhibitor				Inhibition of the renal tubular secretion of ACE inhibitor
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 Lisinopril caused by Probenecid mediated competitive inhibition of renal tubular secretion
