Efficacy and tolerability of sequential intravenous/oral moxifloxacin therapy in pneumonia: results of the first post-marketing surveillance study with intravenous moxifloxacin in hospital practice.

objectiveThis study aimed to investigate the efficacy, safety and tolerability of sequential intravenous (IV)/oral therapy with moxifloxacin in pneumonia under general hospital treatment conditions. PATIENTS AND

methodsPatients with pneumonia were documented in this non-interventional multicentre study. The patients were treated with IV moxifloxacin or moxifloxacin sequential therapy (IV and oral) in hospitals throughout Germany. Exclusion criteria were limited to the contraindications mentioned in the summary of product characteristics. The participating hospital-based physicians documented the patients' demography, anamnesis, antibiotic pretreatment, concomitant diseases and medications. Moxifloxacin therapy and symptom status were recorded daily up to the ninth day and on the last day of treatment. The physicians assessed the efficacy and tolerability of IV moxifloxacin therapy and reported all adverse events observed within the treatment period.

resultsThe 1749 documented patients had a mean age of 66.2 (SD 15.5) years; 56.4% were males and 43.5% females. The majority (99.3%) were treated with moxifloxacin 400mg once daily. On average, moxifloxacin was given for 7.6 days (SD 3.2). In cases of sequential therapy (78.9% of patients), IV moxifloxacin was switched to oral moxifloxacin after a mean of 4.1 days (SD 1.8). Moxifloxacin produced a significant clinical improvement in 58.2% of patients by day 3 of therapy, in 84.2% by day 5 and in 89.4% by day 7. Recovery occurred in 27.0% of patients by day 5, in 54.0% by day 7 and in 87.0% by day 14. It took a mean of 3.4 days (SD 1.9) until improvement and 7.2 days (SD 3.0) until cure. Overall efficacy of IV moxifloxacin therapy was rated by the physicians as 'very good' or 'good' in 82.9% of patients. Tolerability was rated in 94.3% of patients as 'very good' or 'good'. Adverse events were recorded for 92 (5.3%) patients, but events were considered by the attending physician to be related to moxifloxacin therapy for only 45 patients (2.6%).

conclusionsIV moxifloxacin shows high efficacy in the treatment of pneumonia under routine clinical treatment conditions. IV moxifloxacin relieves pneumonia-associated symptoms rapidly and allows an early switch to oral administration. Because of its high efficacy and very good safety and tolerability profile, moxifloxacin delivers excellent benefits as first-line therapy for pneumonia.
