Cefuroxime is a parenteral or oral second-generation cephalosporin antibiotic. This antibiotic was discovered by the Glaxo company, now GlaxoSmithKline, and it was first marketed in 1978 as Zinacef. Zinacef was approved by the U.S. Food and Drug Administration on Oct 19, 1983.[1] The generic form of cefuroxime is also called "Ceftin". The 17-year patent for this antibiotic has now expired in the United States, hence the patent "rights" to produce this medication are now irrelevant.

In the United States this antibiotic is also sold as "Zinacef" by Covis Pharmaceuticals.[2] In India, this antibiotic is sold as Supacef by GSK.[3]

Cefuroxime axetil is an acetoxyetyl-ester-prodrug of cefuroxime which is effective orally.[4] In Bangladesh, this drug is available as Xorimax by Sandoz, Turbocef by Beximco Pharmaceuticals Limited.
