DESCRIPTION Cephalexin, USP is a semisynthetic cephalosporin antibiotic intended for oral administration. It is 7- (D- α-Amino-α-phenylacetamido)-3-methyl-3-cephem-4-carboxylic acid monohydrate. Cephalexin has the molecular formula C H N O S • H O and the molecular weight is 365.41. Cephalexin has the following structural formula: The nucleus of cephalexin is related to that of other cephalosporin antibiotics. The compound is a zwitterion; i.e., the molecule contains both a basic and an acidic group. The isoelectric point of cephalexin in water is approximately 4.5 to 5. The crystalline form of cephalexin which is available is a monohydrate. It is a white crystalline solid having a bitter taste. Solubility in water is low at room temperature; 1 or 2 mg/mL may be dissolved readily, but higher concentrations are obtained with increasing difficulty. The cephalosporins differ from penicillins in the structure of the bicyclic ring system. Cephalexin has a _D_-phenylglycyl group as substituent at the 7-amino position and an unsubstituted methyl group at the 3- position.
