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 white to off white granular
powder with characteristic
flavor, and gives orange colored viscous suspension after
reconstitution with water.
After mixing, each 5 mL of Cephalexin for Oral Suspension, USP, will
contain cephalexin monohydrate
equivalent to 125 mg or 250 mg of anhydrous cephalexin. The
suspensions also contains the following
inactive ingredients: colloidal silicon dioxide, FD&C Yellow No.6,
tutti-frutti flavor, orange flavor,
sodium lauryl sulphate, sucrose and xanthan gum.
