By killing the bacteria and preventing its spread in the body, the penicillin class of medications treat various infections. The antibiotic works by preventing penicillin binding protein 1 and other proteins from certain reactions that result in cross linking in the bacterial cell walls. This action prevents the enzymes from building or repairing cell walls. As a consequence, bactericidal action is the outcome, thereby treating the infection. The antibiotic keeps the bacteria in a static phase of growth and prevents it from proliferating. The bactericidal tag is attributed to the mechanism of action where the death of the bacteria helps in treating infections effectively.

Overview of the antibiotic and side effects of amoxicillin

Before we look at the side effects of amoxicillin it is necessary to understand more about the formulation and the manner in which it works. For instance, amoxicillin, like man other antibiotics actually delivers results in a short time, with patients reporting improvements in just a few days.
