Antibiotic Group

11/12/2010

Question:

Hi guy, how many antibiotic groups are there? I found a new medicine call Pyostacine and it belongs to the group of Streptogramin and I have never heard of this group. Is it a new group of antibiotic?

Answer:

Pyostacine is a brand of the antibacterial combination drug containing Quinupristin and Dalfopristin.   The brand name of the product in the United States is Synercid.

This antibiotic is reserved for treatment of life-threatening infections caused by bacteria that are resistant to the standard antibiotic drugs.

This drug belongs to a relatively new class of antibiotics called Streptogramins.

There are numerous classes or groups of antibiotics.   The link below offers additional information on antibiotics as well as antibiotic drug resistance.
