Difference between Penicillin and Amoxicillin
Penicillin and amoxicillin are antibotics, compounds that stop and destroy bacteria. In fact, penicillin is a precursor to amoxicillin and, in turn, both antibiotics are derived from a fungus called benzylpenicillin . The discovery of penicillin’s effect on bacteria led to a revolution in medical treatment and the development of dozens of other antibiotics, including amoxicillin, which is a cheaper antibiotic that treats a broader spectrum of Gram-positive bacteria and is less likely to cause allergic reactions.
As for amoxicillin, it was originally patented and sold under the trade name Amoxil . As soon as the patent expired, many other patentable amoxicillin/clavulanic acid combinations were developed, including the well-known Augmentin , which is no longer on patent. It is worth mentioning that derivatives of amoxicillin are very common and are found under numerous names.
