Sintesi

Cefotetan has an N-methylthiotetrazole side chain that can cause hypoprothrombinemia and bleeding, which may add to the anticoagulant effect of argatroban. The risk is greater in patients who are debilitated, poorly nourished, or have renal impairment.

Cosa significa questa interazione in parole semplici

Argatroban and Cefotetan can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Argatroban belongs to Cardiovascular; Cefotetan belongs to Anti Bacterial.

Livello di evidenza: Low

Perché avviene

Additive pharmacodynamic effect: the N-methylthiotetrazole group inhibits vitamin K epoxide reductase, reducing clotting factor synthesis.

Cosa fare

Monitor aPTT, PT/INR and for bleeding. Consider a cephalosporin without this side chain, or give vitamin K if coagulopathy develops.
