The top three antibiotics are Amoxicillin, Amoxicillin clavulanate or Augmentin and Azithromycin.
Amoxicillin is a penicillin type antibiotic which is often the first choice for many common types of infections such as skin infections, pneumonia, ear infections and even urinary tract infections.
Amoxicillin clavulanate or Augementin is a combination antibiotic that combines amoxicillin with clavulanate, which helps to overcome some certain types of bacterial resistance.
Augmentin is frequently used in treating of ear infections, respiratory tract infections and other conditions in which resistance may be a concern.
Azithromycin is a macrolide antibiotic which is effective against a range of bacteria and is often used for skin infections, some sexually transmitted infections and respiratory infections.
The most powerful or potent antibiotics are carbapenems like imipenem and meropenem and are used for more serious infections or when resistance to antibiotics occurs.
Vancomycin is also another powerful antibiotic and is often used as a last resort due to it's effectiveness against multi drug resistant bacteria, although resistance to vancomycin has also emerged in some strains.
A newly discovered antibiotic is Clovibactin, which also shows great promise in combating of multi drug resistant bacteria by targeting of a broad spectrum of pathogens in a unique way.
