Sintesi
Iodinated contrast can cause acute kidney injury, and metformin is eliminated unchanged by the kidneys. Reduced clearance leads to metformin accumulation and raises the risk of lactic acidosis.
Cosa significa questa interazione in parole semplici
Contrast media and Linagliptin-metformin can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Perché avviene
Contrast-induced reduction in renal function decreases renal elimination of metformin, causing accumulation.
Cosa fare
Hold metformin at the time of or before the procedure in patients with reduced eGFR, liver disease, alcoholism, heart failure or intra-arterial contrast. Re-check renal function about 48 hours afterward and restart only if it is stable.
Cosa chiedere al farmacista
