Traditionally, serious lower respiratory tract infections (LRTIs) are
treated in hospital and with parenteral antibiotics. During the past d
ecade, there has been an impetus to reduce the overall cost of antimic
robial therapy. The availability of new oral antibiotics with superior
pharmacokinetics profiles and safety has enabled clinicians increasin
gly to consider their use in managing serious infections effectively.
This article retie rvs the current published literature regarding the
practice of switch therapy for LRTIs, examining the evidence for effic
acy, safety, appropriate timing of the switch, the economic benefits,
and the suitability of various antibiotics. There is an emphasis on co
mparing current European and US experience and examining key strategie
s in implementing such programs and means of assessing their impact.
