Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Avelox (Moxifloxacin, BAY12-8039)
Treatment: Drugs - Amoxicillin clavulanic acid

Active Comparator: Arm 2 -

Experimental: Arm 1 -


Treatment: Drugs: Avelox (Moxifloxacin, BAY12-8039)
Subjects will be randomised to moxifloxacin 400 mg PO OD (5 days). Subjects will also take placebo tablets, so that each subject takes 3 tablets per day for 7 days. Prior to randomization, subjects are stratified based on co-administration of short-course systemic steroids.

Treatment: Drugs: Amoxicillin clavulanic acid
Subjects will be randomised to amoxicillin-clavulanic acid 875/125 mg PO BID (7 days). Subjects will also take placebo tablets, so that each subject takes 3 tablets per day for 7 days. Prior to randomization, subjects are stratified based on co-administration of short-course systemic steroids.
