Cefprozil

Cefprozil in Kenya: Cefprozil Chemical Structure

Mechanism of Action

Second-generation cephalosporin that binds to one or more of the penicillin-binding proteins, which in turn inhibits cell wall synthesis and results in bactericidal activity. Has gram-positive activity that first-generation cephalosporins have and adds activity against P mirabilis, H influenzae, E coli, K pneumoniae, and M catarrhalis

INDICATIONS:

Cefprozil is indicated for the treatment of patients with mild to moderate infections caused by susceptible strains of the designated microorganisms in the conditions listed below:

UPPER RESPIRATORY TRACT

Pharyngitis/tonsillitis caused by Streptococcus pyogenes.

NOTE: The usual drug of choice in the treatment and prevention of streptococcal infections, including the prophylaxis of rheumatic fever, is penicillin given by the intramuscular route. Cefprozil is generally effective in the eradication of Streptococcus pyogenes from the nasopharynx

Otitis Media caused by Streptococcus pneumoniae, Haemophilus influenzae (including β-lactamase-producing strains), and Moraxella (Branhamella) catarrhalis (including β-lactamase-producing strains).

NOTE: In the treatment of otitis media due to β-lactamase producing organisms, cefprozil had bacteriologic eradication rates somewhat lower than those observed with a product containing a specific β-lactamase inhibitor. In considering the use of cefprozil, lower overall eradication rates should be balanced against the susceptibility patterns of the common microbes in a given geographic area and the increased potential for toxicity with products containing β-lactamase inhibitors.

Acute Sinusitis caused by Streptococcus pneumoniae, Haemophilus influenzae (including β-lactamase-producing strains), and Moraxella (Branhamella) catarrhalis (including β-lactamase-producing strains).

LOWER RESPIRATORY TRACT

Acute Bacterial Exacerbation of Chronic Bronchitis caused by Streptococcus pneumoniae, Haemophilus influenzae (including β-lactamase-producing strains), and Moraxella (Branhamella) catarrhalis (including β-lactamase-producing strains).

SKIN AND SKIN STRUCTURE

Uncomplicated Skin and Skin-Structure Infections caused by Staphylococcus aureus (including penicillinase-producing strains) and Streptococcus pyogenes. Abscesses usually require surgical drainage.

CONTRAINDICATIONS:

Cefprozil is contraindicated in patients with known allergy to the cephalosporin class of antibiotics.

ADVERSE REACTIONS:

The adverse reactions to cefprozil are similar to those observed with other orally administered cephalosporins. Cefprozil was usually well tolerated in controlled clinical trials. Approximately 2% of patients discontinued cefprozil therapy due to adverse events.

The most common adverse effects observed in patients treated with cefprozil are:

Gastrointestinal: Diarrhea (2.9%), nausea (3.5%), vomiting (1%), and abdominal pain (1%).

Hepatobiliary: Elevations of AST (SGOT) (2%), ALT (SGPT) (2%), alkaline phosphatase (0.2%), and bilirubin values (<0.1%). As with some penicillins and some other cephalosporin antibiotics, cholestatic jaundice has been reported rarely.

Hypersensitivity: Rash (0.9%), urticaria (0.1%). Such reactions have been reported more frequently in children than in adults. Signs and symptoms usually occur a few days after initiation of therapy and subside within a few days after cessation of therapy.

CNS: Dizziness (1%), hyperactivity, headache, nervousness, insomnia, confusion, and somnolence have been reported rarely (<1%). All were reversible.

Hematopoietic: Decreased leukocyte count (0.2%), eosinophilia (2.3%).

Renal: Elevated BUN (0.1%), serum creatinine (0.1%).

Other: Diaper rash and superinfection (1.5%), genital pruritus and vaginitis (1.6%).

CEFPROZIL DRUG INTERACTIONS

  • Nephrotoxicity has been reported following concomitant administration of aminoglycoside antibiotics and cephalosporin antibiotics.
  • Concomitant administration of probenecid doubled the AUC for cefprozil.
