Cas no 121123-17-9 (Cefprozil monohydrate)

Cefprozil monohydrate is a semi-synthetic cephalosporin antibiotic with a broad spectrum of activity against Gram-positive and Gram-negative bacteria. Its monohydrate form enhances stability and solubility, making it suitable for oral formulations. The compound exhibits efficacy against common pathogens such as Streptococcus pneumoniae, Haemophilus influenzae, and Staphylococcus aureus, making it valuable in treating respiratory, skin, and soft tissue infections. Its β-lactamase stability and favorable pharmacokinetic profile, including high oral bioavailability and prolonged half-life, contribute to its clinical utility. Cefprozil monohydrate is widely used in both pediatric and adult populations due to its reliable absorption and minimal side effects.
