  • 12. CEFTAROLINE fosamil(Teflaro)Teflaro) oIts an advanced generation cephalosporin antibiotic active against methicillin-Resistant Staphylococcus aureus(MRSA) and Gram positive bacteria.It retains the activity of later generation cephalosporins having broad spectrum activity against Gram-ve bacteria.Its currently being investigated for community acquired pneumonia and complicated skin and skin structure infections. Ceftaroline is developed by Forest laboratories,USA and received approval on October 29-2010.
  • 13. FIDAXOMICIN (Dificid) Its the first in a new class of narrow spectrum macrocyclic antibiotic.Its an fermentation product obtained from the actinomycete dactylosporangium aurantiacum subspeices. Its an non-systemic , bactericidal and has demonstarted selective eradication of pathogenic “Clostridium difficile “with minimal disruption to multi speices of bacteria that’s make up the normal healthy Intestinal flora. FIDAXOMICIN is approved by by US FDA on April 10,2011 and is marketed by Optimer Pharmaceuticals by trade name Dificid for the treatment of Clostridium difficile infection. Mechanism of action It works by inhibiting the bacterial enzyme RNA polymerase resulting the death of Clostridium difficile .
