AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
Metronidazole is a nitroimidazole antibiotic approved in 1983 that treats infections caused by obligate anaerobic bacteria and certain protozoa. It works by entering anaerobic organisms, being reduced intracellularly, and generating free radicals that degrade bacterial DNA, leading to cell death. The drug is administered orally as a tablet and remains a foundational antimicrobial agent across multiple therapeutic areas.
LOE Approaching
As a legacy product approaching loss of exclusivity with moderate competitive pressure (30), the brand team is likely focused on cost management and maintaining formulary position rather than growth.
Mechanism of Action
Mechanism of Action Metronidazole, a nitroimidazole, exerts antibacterial effects in an anaerobic environment against most obligate anaerobes. Once metronidazole enters the organism by passive diffusion and is activated in the cytoplasm of susceptible anaerobic bacteria, it is reduced; this process…
