Cefamandole (Mandol) nafate is the formate ester ofcefamandole, a semisynthetic cephalosporin that incorporates D-mandelic acids as the acyl portion and a thiol-containingheterocycle (5-thio-1,2,3,4-tetrazole) in place of the acetoxylfunction on the C-3 methylene carbon atom. Esterification ofthe α-hydroxyl group of the D-mandeloyl function overcomesthe instability of cefamandole in solid-state dosage formsand provides satisfactory concentrations of the parent antibioticin vivo through spontaneous hydrolysis of the ester atneutral to alkaline pH. Cefamandole is the first second-generationcephalosporin to be marketed in the United States.<br>The D-mandeloyl moiety of cefamandole appears toconfer resistance to a few β-lactamases, since some β-lactamase–producing, Gram-negative bacteria (particularlyEnterobacteriaceae) that show resistance to cefazolin andother first-generation cephalosporins are sensitive tocefamandole. Additionally, it is active against some ampicillin-resistant strains of Neisseria and Haemophilus spp.Although resistance to β-lactamases may be a factor in determiningthe sensitivity of individual bacterial strains tocefamandole, an early study indicated that other factors,such as permeability and intrinsic activity, are frequentlymore important. The L-mandeloyl isomer is significantlyless active than the D-isomer.<br>Cefamandole nafate is very unstable in solution andhydrolyzes rapidly to release cefamandole and formate.There is no loss of potency, however, when such solutionsare stored for 24 hours at room temperature or up to 96hours when refrigerated. Air oxidation of the released formateto carbon dioxide can cause pressure to build up in theinjection vial.<p>The D-mandeloyl moiety of Cemandil sodium salt appears toconfer resistance to a few β-lactamases, since some β-lactamase–producing, Gram-negative bacteria (particularlyEnterobacteriaceae) that show resistance to cefazolin andother first-generation cephalosporins are sensitive tocefamandole.
