Elimination of cefmenoxime during continuous haemofiltration.

The elimination of cefmenoxime after single and repeated i.v. dosing was studied in 12 patients with severe renal failure and sepsis during continuous haemofiltration. More than 30% of the drug was found in the filtrate. The sieving coefficient (S) was 0.54. Vss% was unchanged 0.31 l.kg-1 in comparison with patients with normal renal function, whereas the mean t1/2ss was prolonged to about 16 h, and total clearance was reduced 20.8 ml.min-1.1.73 m-2. Once daily administration of 1 g cefmenoxime is suggested as the appropriate dose under such circumstances.
