Key Clinical Findings (2020–2023)
- Efficacy: Cefprozil remains effective, with clinical cure rates exceeding 90% in uncomplicated respiratory infections. Resistance remains low but shows increasing MICs (minimum inhibitory concentrations) in S. pneumoniae strains, indicating potential emerging resistance.
- Safety: Consistent safety profile aligned with previous data; minor adverse events include gastrointestinal disturbances and hypersensitivity reactions.
- Resistance Patterns: Surveillance indicates a slight uptick in beta-lactamase-producing bacterial strains, consistent with global antimicrobial resistance (AMR) trends.
Regulatory Updates
- FDA: No new indications or label updates since 2017.
- EMA: Approved for similar indications; ongoing post-market surveillance emphasizes resistance monitoring.
- Clinical Practice Guidelines: Cefzil usage remains recommended for specific infections with no major deviations.
