I knew you'd say that, same thing the ID guy at my previous institution said. For linezolid to be blown out of the water, we have to pray that ZEPHYR is done right, and the data is analyzed and reported objectively (with Pfizer as the sponsor, HEH). However, at least they are monitoring serum concentrations and maintaining troughs between 15-20. Could actually be a fair fight.

c'mon dood... how will 15mg/kg q12h adjsted to renal fxn give you a trough between 15-20ug/ml? Eh?
15mg/kg give you an extrapolated peak of maybe 20ug/ml..in 2 half lives...trough is 5ug/ml..... at steady state, you're looking at trough of 7ug/ml and peak of 30ug/ml.
I know you can do this in your head...
That study is already f'cked up..... Vanco dosing isn't sufficient. We're shooting at 25mg/kg to get the peak near 40.
