cefotiam
Cefotiam is a parenteral second-generation cephalosporin antibiotic. It has broad-spectrum activity against Gram-positive and Gram-negative bacteria. As a beta-lactam, its bactericidal activity results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins.
Cefotiam was launched as Pansporin in February 1981 by Takeda Pharmaceutical of Japan and has been available as a generic since February 1993.
==Mechanism of action==
Cefotiam inhibits final cross-linking stage of peptidoglycan production, thus inhibiting bacterial cell wall synthesis. It has similar or less activity against Gram-positive staphylococci and streptococci, but is resistant to some beta-lactamases produced by Gram-negative bacteria. It is more active against many of the Enterobacteriaceae including ''Enterobacter, E. coli, Klebsiella, Salmonella'' and indole-positive ''Proteus'' species.
In clinical use, high concentrations of cefotiam are observed in several tissues (kidney, heart, ear, prostate, and genital tract), as well as in fluids and secretions (bile, ascitic fluid).
