DESCRIPTION
Cephalexin Capsules, USP is a semisynthetic cephalosporin antibiotic
intended for oral administration.
It is 7-(D-a-Amino-a-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, USP 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
phenylglycyl group as substituent at the
7 amino position and an unsubstituted methyl group at the 3 position.
Each capsule contains cephalexin
monohydrate equivalent to 250 mg (720 µmol) or 500 mg (1439 µmol) of
cephalexin. The capsules also
contain the following inactive ingredients magnesium stearate, capsule
