Pharmacology
Cefuroxime is a well-characterized and effective antibacterial agent, which has broad-spectrum bactericidal activity against a wide range of common pathogens, including ?ý-lactamase producing strains. Cefuroxime has good stability to bacterial ?ý-lactamase and consequently, is active against many ampicillin-resistant and amoxycillin-resistant strains.

Interaction
No potentially hazardous interactions have been reported.

Contradiction
Cefuroxime is contraindicated in patients with known allergy to Cephalosporins.

Side Effect
Adverse effects to Cefuroxime have occurred infrequently and have been generally mild and transient in nature. Effects reported include rashes and gastrointestinal disturbances. As with other antibiotics, prolonged use may result in the overgrowth of non susceptible organisms e.g. Candida.

Pregnancy
US FDA pregnancy category of Cefuroxime is B. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Cefuroxime have been shown to be excreted in human milk. So, caution should be exercised when Cefuroxime is administered to a nursing woman.

Precaution
Cefuroxime should be given with care to patients receiving concurrent treatment with potent diuretics & who has history of colitis. Cephalosporin antibiotics may in general be given safely to patients who are hypersensitive to penicillin although cross reactions have reported. Cefuroxime has shown, that is not likely to be a problem at the recommended to dose levels.
