Loracarbef (LY163892) vs Amoxicillin/Clavulanate in Bacterial Maxillary Sinusitis

Loracarbef (LY 163892), a beta-lactam antibiotic (carbacephem), was compared with amoxicillin/clavulanate potassium in a 10-day, single-blind, randomized parallel trial in the treatment of acute bacterial maxillary sinusitis. Based on posttherapy aspirate and culture, there was a 95.2% bacteriologic cure rate in patients receiving loracarbef (400 mg twice daily) and an 86.7% cure rate in patients receiving amoxicillin/clavulanate (500/125 mg three times daily) (p = 0.359). Loracarbef was comparable in efficacy to amoxicillin/clavulanate with a more desirable safety profile.
