Drug Class and Mechanism

Amoxil is an antibiotic that belongs to a class of antibiotics called penicillins.

These antibiotics all have a similar mechanism of action. They do not kill bacteria, but they stop 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.

Amoxil is effective against many different bacteria including H. influenzae, N. gonorrhoea, E. coli, Pneumococci, Streptococci, and certain strains of Staphylococci.
