AB Antibiotics  are  the  foundation  of  therapy  for  respiratory  tract  infections.  The  approach  to  use  varies  with  the  type  of  pneumonia,  age  of  the  affected  patient,  presence  of  various  comorbid  illnesses,  risk  factors  for  infection  by  specific  pathogens,  and  severity  of  the  acute  illness.  For  most  patients,  initial  therapy  is  empiric,  aimed  at  a  broad  spectrum  of  potential  pathogens.  Once  culture  data  become  available,  therapy  can  be  pathogen-specific  making  it  possible  to  de-escalate  to  fewer  drugs  with  a  narrower  antimicrobial  spectrum.1  In  some  cases,  initial  empiric  therapy  must  be  continued  because  no  etiologic  pathogen  is  identified.
