Cefprozil is a second-generation cephalosporin antibiotic. [1] Originally discovered in 1983, and approved in 1992, [2] it was sold under the tradename Cefzil by Bristol Meyers Squibb until 2010 when the brand name version was discontinued. [3] It continues to be available from various companies in its generic form. [4] It is used in the treatment of pharyngitis, tonsillitis, ear infections, acute sinusitis, bacterial exacerbation of chronic bronchitis, and skin and skin structure infections. [5] It is currently available as a tablet and as a liquid suspension.

Adverse effects

Although there is a widely quoted cross-allergy risk of 10% between cephalosporins and penicillin, research has shown no increased risk for cross-allergy for cefprozil and several other second-generation or later cephalosporins. [6] The most common side effects were increased hepatic lab values (including AST and ALGT), dizziness, eosinophilia, diaper rash and superinfection, genital pruritus, vaginitis, diarrhea, nausea, vomiting, and abdominal pain. [5]

Spectrum of bacterial susceptibility and resistance

Currently, bacteria like Enterobacter aerogenes , Morganella morganii and Pseudomonas aeruginosa are resistant to cefprozil, while Salmonella enterica serotype Agona and streptococci are susceptible to cefprozil. Some bacteria like Brucella abortus , Moraxella catarrhalis and Streptococcus pneumoniae have developed resistance towards cefprozil in varying degrees. Detailed minimum inhibition concentration information is given by the Cefprozil Susceptibility and Resistance Data sheet. [7]

Synthesis

Cefprozil synthesis: Separation of isomers: Cefprozil synthesis.svg
Cefprozil synthesis: Separation of isomers:

Displacement of the allylic chloride in intermediate (1) with triphenylphosphine gives the phosphonium salt (2). This functionality is then converted to its ylide; condensation with acetaldehyde then leads to the vinyl derivative (3); deprotection then gives cefprozil. Semisynthetic oral cephalosporin consisting of ~90:10 Z/E isomeric mixture. [12] [13]
