It will not work for viral infections such as flu or the common cold. Using any antibiotic when you do not need it can make it less effective for future infections.

MECHANISM

Cefuroxime Axetil is a semisynthetic, broad-spectrum cephalosporin antibiotic for oral administration. 


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. 


 

Indications

  • Pharyngitis/Tonsillitis

  • Acute Bacterial Otitis Media 

  • Urinary Tract Infections

  • Gonorrhea

  • Lyme Disease (erythema migrans). 

  • Skin Infections

  • Pneumonia 

  • Post Surgery infection management 

  • Bacterial Infections

 

MECHANISM OF ACTION:

Cefuroxime, like the penicillins, is a beta-lactam antibiotic. By binding to specific penicillin-binding proteins (PBPs) located inside the bacterial cell wall, it inhibits the third and last stage of bacterial cell wall synthesis. Cell lysis is then mediated by bacterial cell wall autolytic enzymes such as autolysins; it is possible that cefuroxime interferes with an autolysin inhibitor. 

Pharmacokinetics:


Bioavailability

37% on empty stomach,

up to 52% if taken after food, 


Half-life

80 minutes 


Excretion

Urine 66-100% Unchanged


Pharmacology:


Cefuroxime is a β-lactam type antibiotic. More specifically, it is a second-generation cephalosporin. Cephalosporins work the same way as penicillins: they interfere with the peptidoglycan synthesis of the bacterial wall by inhibiting the final transpeptidation needed for the cross-links. This effect is bactericidal. Cefuroxime is effective against the following organisms: Aerobic Gram-positive Microorganisms: Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes. Aerobic Gram-negative Microorganisms: Escherichia coli, Haemophilus influenzae (including beta-lactamase-producing strains), Haemophilus parainfluenzae, Klebsiella pneumoniae, Moraxella catarrhalis (including beta-lactamase-producing strains), Neisseria gonorrhoeae (including beta-lactamase-producing strains). Spirochetes: Borrelia burgdorferi. Cefuroxime axetil is the prodrug.

Absorption: It is absorbed from the gastrointestinal tract. Absorption is greater when taken after food (absolute bioavailability increases from 37% to 52%).


Protein binding: 50% to serum protein.


Metabolism: The Cefamy moiety is metabolized to acetaldehyde and acetic acid.

Half life: It's half life is Approximately 80 minutes following intramuscular or intravenous injection.
