Active Ingredients:
Cefaclor

Therapeutic actions:
Inhibits bacterial cell wall synthesis by binding to one or more of the penicillin-binding proteins (PBPs) which in turn inhibits the final transpeptidation step of peptidoglycan synthesis in bacterial cell walls, thus inhibiting cell wall biosynthesis. Bacteria eventually lyse due to ongoing activity of cell wall autolytic enzymes (autolysins and murein hydrolases) while cell wall assembly is arrested.

What is it used for?:
Ceclor, a cephalosporin antibiotic, is used in the treatment of ear, nose, throat, respiratory tract, urinary tract, and skin infections caused by specific bacteria, including staph, strep, and E. coli. Uses include treatment of sore or strep throat, pneumonia, and tonsillitis. Ceclor CD, an extended release form of the drug, is also used for flare-ups of chronic bronchitis.
