tcsc2823 Ceftaroline fosamil

Ceftaroline fosamil is a cephalosporin with activity against Gram-positive pathogens, including methicillin-resistant Staphylococcus aureus (MRSA).

In Vivo: Ceftaroline fosamil is effective against all 10 MRSA isolates used in the dose-ranging studies and requires approximately 17 to 43% fT>MIC (the percentage of time that free drug concentrations remain above the MIC) to produce a 1-log₁₀ kill^[1]. The Ceftaroline Fosamil treatment results in mean reductions of 1.1 to 2.4 log₁₀ CFU, with no relationship to the Ceftaroline Fosamil MIC. The use of high inocula does not affect the Ceftaroline Fosamil efficacy against the three strains tested, with mean decreases of 2.0 to 3.0 log₁₀ CFU^[2].
