Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate the efficacy and tolerability of intravenously administered azithromycin given as a 1.5 g single dose compared to 500 mg daily dose over a period of 3 days in patients suffering from community-acquired pneumonia. If azithromycin treatment administered intavenously as a 1.5 g dose can be proven therapeutically equivalent or not inferior to 500 mg administered intravenously over a period of 3 days, treatment of CAP patients can be optimised. This short regimen has the potential for enhancement of patient compliance and will lead to a reduction of costs because of minimisation of hospitalisation days. It even provides the possibility of outpatient treatment administration in patients with minor compliance. ;Secondary Objective: Microbiological cure/failure, frequency of adverse events, death, additionally required therapeutic measures and dynamics of x-ray findings will be evaluated ;Primary end point(s): For the evaluation of clinical efficacy, outcome is defined as clinical cure, failure or indeterminate. Efficacy will be evaluated in both study groups.
