Property：
Cephalexin Monohydrochloride is a
semisynthetic cephalosporin antibiotic with antimicrobial
activity similar to that of CEPHALORIDINE or CEPHALOTHIN,
but somewhat less potent. It is effective against both
gram-positive and gram-negative organisms. The characteristic
of Cephalexin Monohydrochloride is white or almost white
crysalline powder.

Usage:
Cefalexin is used to treat urinary tract
infections, respiratory tract infections, and skin and
soft tissue infections. Cefalexin is also sometimes used
to treat acne.
In addition to being a rational first-line
treatment for cellulitis, cefalexin is a useful alternative
to penicillins in patients with penicillin hypersensitivity.
In patients with mild or questionable history of penicillin
allergy, cephalasporins are now thought to be relatively
safe. Caution should always be taken when prescribing
cephalosporins to those with strong history of true
penicillin hypersensitivity, however, because cefalexin and
other first-generation cephalosporins are known to have a
modest cross-allergy in patients with penicillin
hypersensitivity.
