Cefoperazone sodium salt is a cephalosporin antibiotic for inhibition of rMrp2-mediated [3H]E217βG uptake with IC50 of 199 μM. Target: Antibacterial Cefoperazone is a sterile, semisynthetic, broad-spectrum, parenteral cephalosporin antibiotic for intravenous or intramuscular administration. After intravenous administration of 2 g of Cefoperazone, levels in serum rang from 202μg/mL to 375 μg/mL depending on the period of drug administration. After intramuscular injection of 2 g of Cefoperazone, the mean peak serum level is 111 μg/mL at 1.5 hours. At 12 hours after dosing, mean serum levels are still 2 to 4 μg/mL. Cefoperazone is 90% bound to serum proteins.
