Hemodialysis-Associated Infections: Treatment with Cephapirin [PDF]

Antimicrobial Agents and Chemotherapy, 1978
Large doses of cephapirin (50 mg/kg) administered during the first and last half hours of routine hemodialysis produced effective antimicrobial serum concentrations for 48 h. Repetitive administration during five successive hemodialysis sessions did not result in accumulation or accelerated metabolism of cephapirin.
