Sparfloxacin, a new synthetic quinolone antimicrobial agent, was admin
istered to 20 patients with mycoplasmal pneumonia to evaluate its clin
ical efficacy and adverse effects. The efficacy rate was 100%. In all
cases, the subjective symptoms, chest x-ray findings and inflammatory
response improved within 5 days after sparfloxacin administration. The
re were no adverse events including abnormal laboratory values in any
of the patients during the treatment period, and no adverse effects th
at were thought to be due to sparfloxacin were encountered. Since spar
floxacin displays an excellent activity against Mycoplasma pneumoniae
and has a broad spectrum of antimicrobial activity against not only Gr
am-negative bacteria but also Gram-positive bacteria, Legionella, Chla
mydia and acid-fast bacteria, it appears to be useful as the drug of f
irst choice in the treatment of respiratory tract infections.
