Cefamandole (also known as cephamandole) is a broad-spectrum cephalosporin antibiotic. The clinically used form of cefamandole is an ester form, cefamandole nafate, a prodrug. Cefamandole is no longer available in USA, but it has prescription in UK. Cefamandole under brand name mandol is indicated for the treatment of serious infections caused by susceptible strains of the designated microorganisms such as: lower respiratory infections, including pneumonia, caused by S. pneumoniae. So as urinary tract infections caused by E. coli, Proteus spp.; peritonitis caused by E. coli and Enterobacter spp. Septicemia caused by E. coli; skin and skin structure infections caused by S. aureus; bone and joint infections caused by S. aureus (penicillinase- and non-penicillinase-producing). Like all beta-lactam antibiotics, cefamandole binds to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, causing the inhibition of the third and last stage of bacterial cell wall synthesis. Bacterial cell wall autolytic enzymes such as autolysins then mediate cell lysis; it is possible that cefamandole interferes with an autolysin inhibitor.

The usual dosage range for cefamandol (cefamandole) is 500 mg to 1 g every 4 to 8 hours. In infections of skin structures and in uncomplicated pneumonia, a dosage of 500 mg every 6 hours is adequate. In uncomplicated urinary tract infections, a dosage of 500 mg every 8 hours is sufficient. In more serious urinary tract infections, a dosage of 1 g every 8 hours may be needed. In severe infections, 1-g doses may be given at 4 to 6-hour intervals. In life-threatening infections or infections due to less susceptible organisms, doses up to 2 g every 4 hours (ie, 12 g/day) may be needed.
Infants and Children: administration of 50 to 100 mg/kg/ day in equally divided doses every 4 to 8 hours has been effective for most infections susceptible to Mandol (cefamandole). This may be increased to a total
daily dose of 150 mg/kg (not to exceed the maximum adult dose) for severe infections.

The intracellular activity of cefamandole against phagocytosed Staphylococcus aureus was studied using a sensitive and standardized method of murine peritoneal macrophages. Cefamandole exerted an intracellular antibacterial activity against E. coli which was greater than their extracellular one. With concentrations of antibiotic up to 16 x MBC a dose-dependent decrease of the initial number of intracellular E. coli which ranged from 32% to 90% was observed. However, similar antibiotic concentrations above the MBC affected the viability of extracellular E. coli by only 20% to 30%. The intracellular antibacterial activity of antibiotic against E. coli was further enhanced by immune serum. Cefamandole at 4 x the MBC did not affect the survival of intracellular S. aureus, but killed 41% of extracellular bacteria by 1 h and 99% after 3 h. The data suggest that cefamandole possesses an intracellular antibacterial activity against E. coli that seems at least in part due to a positive cooperation of antibiotic with the O2-independent microbicidal system of macrophages.
