Pharmacology
Tetracycline-class antibacterial; doxycycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, exhibiting bacteriostatic activity against a broad range of Gram-positive and Gram-negative bacteria.
Ceftolozane is a cephalosporin antibacterial that inhibits bacterial cell wall biosynthesis by binding to penicillin-binding proteins (PBPs); tazobactam is an irreversible beta-lactamase inhibitor that extends ceftolozane activity against beta-lactamase-producing organisms.
