Uses and Reactions

Amoxicillin is also a penicillin, it is used commonly as an antibiotic. Amoxicillin is prescribed for patients with a bacterial infections such as streptococcal pharyngitist . Usually used for infections in the ear, nose, or throat. It can be in a liquid or solid state and is taken orally.

Penicillin was made for human use in 1943 by Alexander Fleming, Ernst Chain and Howard Florey. This new discovery helped save many lives especially during World War II. Although, Penicillin improved the lives of many people, there's always room for improvement. Penicillin didn't last very long and didn't proctect the body from all the infected bacteria. Amoxicillin was this new demand of many patients with the bacterial infections.


Amoxicillin comes from penicillin. Penicillin originates from Penicillium mold. Penicillium mold grows in soil, dieing plants, rotten fruits, and other dried foods. Amoxicillin and Penicillin are antibotics, which are forms of bacteria and fungi.
