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
-phenylglycyl group as substituent at the 7-amino position and an
unsubstituted methyl group at the 3-
position. _D_
Each capsule contains cephalexin USP equivalent to 250 mg or 500 mg of
anhydrous cephalexin. The
capsules also contain the following inactive ingredients D&C Yellow
10, FD&C Blue 1, FD&C Green
3, FD&C Yellow 6, ferric oxide black, gelatin, magnesium stearate,
microcrystalline cellulose,
potassium hydroxide, propylene glycol, shellac and titanium dioxide.
