As judged by the MIC50 and the MIC90 values, cefpiramide was one of the most active cephalosporins against Pseudomonas aeruginosa (MIC50 2.9 micrograms/ml, MIC90 64 micrograms/ml), staphylococci (MIC50 1.2 micrograms/ml, MIC90 10 micrograms/ml) and Enterococcus faecalis (MIC50 13 micrograms/ml, MIC90 43 micrograms/ml). Cefpiramide had moderate activity against Enterobacteriaceae (MIC50 4 micrograms/ml, MIC90 108 micrograms/ml), comparable to that of the older second-generation cephalosporins.
