It has similar spectrum of activity to cefalexin. RESPIRATORY TRACT INFECTIONS (e.g., tonsillitis, pharyngitis, and lobar pneumonia) caused by group A beta-hemolytic streptococci and S. pneumoniae (formerly D. pneumonia). (Penicillin is the usual drug of choice in the treatment and prevention of streptococcal infections, including the prophylaxis of rheumatic fever. Velosef is generally effective in the eradication of streptococci from the nasopharynx; substantial data establishing the efficacy of Velosef in the subsequent prevention of rheumatic fever are not available at present.) OTITIS MEDIA caused by group A beta-hemolytic streptococci, S. pneumoniae (formerly D. pneumoniae), H. influenzae, and staphylococci. SKIN AND SKIN STRUCTURE INFECTIONS caused by staphylococci (penicillin-susceptible and penicillin-resistant) and beta-hemolytic streptococci. URINARY TRACT INFECTIONS, including prostatitis, caused by E. coli, P. mirabilis, Klebsiella species, and enterococci (S. faecalis). The high concentrations of cephradine achievable in the urinary tract will be effective against many strains of enterococci for which disc susceptibility studies indicate relative resistance. It is to be noted that among beta-lactam antibiotics, ampicillin is the drug of choice for enterococcal urinary tract (E. faecalis) infection.

Noting that 1,4-cyclohexadiene rings are nearly as planar as benzene rings but of greatly different reactivity, a cephalosporin was synthesized with such a moiety.
Birch reduction of D-α-phenylglycine led to diene (2). This was N-protected using tert-Butoxycarbonylazide and activated for amide fromation via the mixed anhydride method using isobutylchloroformate to give 3. Mixed anhydride 3 reacted readily with 7-Aminodesacetoxycephalosporanic acid to give, after deblocking, cephadrine (5).
