Uses
Amoxicillin works by binding to penicillin binding proteins within bacteria, which suppress the bacteria’s ability to produce cell walls, leading to death of the bacteria(lysis). Amoxicillin is used to treat a variety of infections including infections of the sinuses, ear, and skin. It can kill gram positive, and some gram negative bacteria.
