Cefamandole lithium
Cefamandole (Cephamandole) lithium is a semi-synthetic second-generation cephalosporin antibiotic with broad-spectrum antimicrobial activity. Cefamandole lithium is resistant to hydrolysis by β-lactamases produced by some Gram-negative bacteria. Cefamandole lithium kills Gram-positive cocci and various Gram-negative bacilli mainly by inhibiting cell wall synthesis, but it is inactive against Pseudomonas, Proteus vulgaris and Providencia stuartii, and its efficacy is affected by inoculum size. The plasma elimination half-life of Cefamandole lithium in rats is only 0.4 h, it is mainly excreted in urine in biologically active form, and it hardly penetrates the non-inflamed blood-brain barrier. Cefamandole lithium is widely used in studies related to bacterial infections.

Biological Activity
Cefamandole lithium (30 μg/mL; 0, 1, 3, 6, 12 h) is hydrolyzed by beta-lactamases from Enterobacter cloacae, Serratia marcescens, and Proteus morganii, allowing bacterial growth to resume after hydrolysis is complete, while Pseudomonas aeruginosa grows despite cefamandole presence prior to hydrolysis[1].
Cefamandole lithium (0.12-64 μg/mL; 18 h) inhibits 90-100% of methicillin-susceptible S. aureus, group A and B streptococci, S. pneumoniae, N. gonorrhoeae, H. influenzae, and S. typhosa[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Cefamandole (50 mg/kg; intravenous administration; single dose) lithium exhibits free drug pharmacokinetic characteristics consistent with a two-compartment model in male Sprague-Dawley rats, with an elimination half-life of 21.6 min[5].
