PRESCRIPTION DRUG
- 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. Cefuroxime axetil tablets are generally effective in the eradication of streptococci from the nasopharynx; however, substantial data establishing the efficacy of cefuroxime in the subsequent prevention of rheumatic fever are not available. Please also note that in all clinical trials, all isolates had to be sensitive to both penicillin and cefuroxime. There are no data from adequate and well-controlled trials to demonstrate the effectiveness of cefuroxime in the treatment of penicillin-resistant strains of Streptococcus pyogenes. - Acute Bacterial Otitis Media caused by Streptococcus pneumoniae , Haemophilus influenzae (including beta-lactamase–producing strains), Moraxella catarrhalis (including beta-lactamase–producing strains), or Streptococcu
Abbreviated New Drug Application
CEFUROXIME AXETIL - CEFUROXIME AXETIL TABLET H.J. HARKINS COMPANY, INC. ---------- CEFUROXIME AXETIL TABLETS, USP To reduce the development of drug-resistant bacteria and maintain the effectiveness of cefuroxime axetil and other antibacterial drugs, cefuroxime axetil should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. DESCRIPTION Cefuroxime axetil tablets contain cefuroxime as cefuroxime axetil. Cefuroxime axetil is a semisynthetic, broad-spectrum cephalosporin antibiotic for oral administration. Chemically, cefuroxime axetil, the 1-(acetyloxy) ethyl ester of cefuroxime, is (_RS _)-1-hydroxyethyl (6_R_,7_R_)-7-[2-(2-furyl)glyoxyl-amido]-3-(hydroxymethyl)-8-oxo-5-thia-1-azabicyclo[4.2.0]-oct-2-ene- 2-carboxylate, 7 -(_Z_)-(_O_-methyl-oxime), 1-acetate 3-carbamate. Its molecular formula is C H N O S, and it has a molecular weight of 510.48. Cefuroxime axetil is in the amorphous form and has the following structural formula: Cefuroxime axetil tablets are uncoated and contain the equivalent of 125, 250 or 500 mg of cefuroxime as cefuroxime axetil. Cefuroxime axetil tablets contain the inactive ingredients colloidal silicon dioxide, croscarmellose sodium, hydrogenated vegetable oil, microcrystalline cellulose and sodium lauryl sulfate. CLINICAL PHARMACOLOGY ABSORPTION AND METABOLISM After oral administration, cefuroxime axetil is absorbed from the gastrointestinal tract and rapidly hydrolyzed by nonspecific esterases in the intestinal mucosa and blood to cefuroxime. Cefuroxime is subsequently distributed throughout the extracellular fluids. The axetil moiety is metabolized to acetaldehyde and acetic acid. 2 20 22 4 10 PHARMACOKINETICS Approximately 50% of serum cefuroxime is bound to protein.
