GENERIC NAME: amoxicillin and clavulanic acid

BRAND NAME: Augmentin, Augmentin XR

DRUG CLASS AND MECHANISM: Augmentin contains amoxicillin and clavulanic acid. Amoxicillin is an antibiotic of the penicillin type. It is effective against some bacteria such as H. influenzae, N. gonorrhea, E. coli, Pneumococci, Streptococci, and certain strains of Staphylococci. Chemically, it is closely related to penicillin and ampicillin. Amoxicillin stops bacteria from multiplying by preventing bacteria from forming the walls that surround them. The walls are necessary to protect bacteria from their environment and to keep the contents of the bacterial cell together. Bacteria cannot survive without a cell wall. Clavulanic acid enhances the effectiveness of amoxicillin against bacteria that are ordinarily resistant to amoxicillin alone.
