What is Quzil (Cefprozil)?

Quzil (Cefprozil) is a second-generation cephalosporin antibiotic used to treat a wide range of bacterial infections. It is effective against gram-positive and gram-negative bacteria responsible for respiratory tract, ear, throat, and skin infections. Quzil belongs to the anti-infective cephalosporin class and is available in oral suspension and tablet forms for both pediatric and adult patients.

Benefits

Quzil (Cefprozil) offers effective antibacterial coverage with high tolerability and a broad therapeutic range. Key benefits include:

• Treats pharyngitis and tonsillitis caused by susceptible bacteria.
• Indicated for otitis media in pediatric patients.
• Effective for secondary bacterial infections of acute bronchitis and bacterial exacerbations of chronic bronchitis.
• Used to treat skin and skin structure infections in adults.
• Convenient once- or twice-daily dosing regimen.
• Well-tolerated alternative for patients allergic to penicillin (with caution).

Dosage & Usage

Quzil (Cefprozil) is available in the following forms and strengths: 125mg suspension, 250mg suspension, and 500mg tablets. Dosage depends on the type of infection and patient age:

• Pharyngitis and Tonsillitis: Adults and children ≥13 years: 500mg once daily for 10 days.
• Otitis Media (Pediatric): 15mg/kg every 12 hours for 10 days (using oral suspension).

How It Works

Cefprozil, the active ingredient in Quzil, inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs). This prevents the formation of peptidoglycan, a crucial component of bacterial cell walls, leading to bacterial death. As a β-lactam antibiotic, Cefprozil exhibits strong activity against common respiratory and skin pathogens including Streptococcus pyogenes, Haemophilus influenzae, and Moraxella catarrhalis.

Who Should Use Quzil (Cefprozil)

Quzil is suitable for adults and children with bacterial infections of the throat, ear, bronchial tract, or skin. It should be used only under the direction of a healthcare professional. Patients with a known allergy to cephalosporins or penicillins should inform their doctor before use. Dosage adjustments may be required in patients with kidney impairment.
