CEPHALEXIN FOR ORAL SUSPENSION USP
Rx only

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.
Cephalexin for Oral Suspension, USP, is a pink colored powder forming
pink colored suspension on
constitution. After mixing, each 5 mL of cephalexin for oral
suspension, will contain cephalexin USP
equivalent to 125 mg (360 µmol) or 250 mg (720 µmol) of anhydrous
cephalexin. The suspension also
contains the following inactive ingredients: colloidal silicon
dioxide, FD&C Red No. 40, sodium
benzoate, strawberry flavor, sucrose, xanthan gum.
