Efficacy and tolerability of flurithromycin ethylsuccinate were evaluated in lower respiratory tract infections. One hundred and ten patients (38 women, 72 men; age range 18–87 years) were treates with on 375 mg tablet 12-hourly for a mean duration of 8.7 days. One hundred and five patients were evaluable for efficacy. Overall clinical cure rate was 62.9%; improvement was recorded in 19% of patients for a total satisfactory clinical response rate of 81.9%. Sputum production decreased in most patients, being absent after treatment in 47% (only one patient was negative at baseline); sputum was purulent or mucopurulent in 80% of subjects before and in 20% after treatment. Bacteriological evaluation was possible in 72 patients: pathogen eradication was achieved in 80.2% of cases. Eight patients out of 110 reported adverse reactions, mainly gastrointestinal; in one case treatment had to be discontinued. These results demonstrate that flurithromycin ethylsuccinate is safe and effective in the treatment of lower respiratory tract infections.


Die Wirksamkeit und Verträglichkeit von Flurithromycin Ethylsuccinat wurde bei Patienten mit Infektionen der tiefen Atemwege geprüft. 110 Patienten (38 Frauen, 72 Männer, im Alter von 18–87 Jahren) erhielten zweimal täglich eine Tablette Flurithromycin Ethylsuccinat zu 375 mg. Insgesamt wurden 62,9% der Patienten klinisch geheilt, 19% gebessert. Die Rate an befriedigendem klinischen Ansprechen lag somit bei 81,9%. Bei den meisten Patienten ging die Sputumproduktion zurück. Bei 47% hatte die Sputumproduktion nach Behandlungsende aufgehört (nur bei einem Patienten bestand zu Therapiebeginn keine Sputumproduktion). Purulentes oder mukopurulentes Sputum bestand vor Behandlung bei 80% und nach Behandlng bei 20% der Patienten. Bei 72 Patienten war eine bakteriologische Befundung möglich. In 80,2% der Fälle wurde der Erreger eliminiert. Bei acht der 110 behandelten Patienten traten Nebenwirkungen auf, die meist den Gastrointestinaltrakt betrafen. In einem Fall mußte die Behandlung abgebrochen werden. Diese Ergebnisse zeigen, daß Flurithromycin Ethylsuccinat ein wirksames und sicheres Medikament für die Behandlung tiefer Atemwegsinfektionen ist.
