Should the Currently Recommended Twice-Daily Dosing Still be Considered the Most Appropriate Regimen for Treating MRSA Ventilator-Associated Pneumonia with Vancomycin?

Meticillin-resistant (methicillin-resistant) Staphylococcus aureus causes unacceptably high mortality from ventilator-associated pneumonia, even when appropriate early therapy with vancomycin is administered at a dosage of 15 mg/kg every 12 hours. However, because of the poor penetration of vancomycin in epithelial lining fluid, it is unlikely that this dosing schedule always achieves optimal vancomycin exposure in the lung. Conversely, there is probably enough evidence to suggest that continuous infusion enhances vancomycin efficacy with the standard 30 mg/kg daily dosage, thus avoiding the need to use higher daily dosages that could increase the risk of nephrotoxicity. It is worth noting that in the case of fully susceptible pathogens with a minimum inhibitory concentration (MIC) of /=360, so that both pharmacodynamic efficacy targets may be optimized.

About Me
- Pat O'Connor
- Am old enough to understand the difference between the Bay of Pigs - and roasting a pig at a epicurian feast. Been thru the hippy, yippie and yuppie years - always remaining who I am. Very much believe in "Sing your own song - weave your own tapestry" Am young enough to still know the thrill of new discoveries, the beauty of the evening, to celebrate the joy of another tommorow. Survived these many decades with a severe medical problems. Sorting out the maze of now having two lymphomas and all their nasty little companions, but I continue. Besides, being a simple iconoclastic eclectic, have been called many things. An incurable romanticist - with a strong touch of reality. Thinker, intellectual (God, how I hate that term) - been told I am a lion with the heart of the poet. Know how to wage war and conquer my foes - but would rather be known as one who brings hope and life. To bring hope into anothers life is the ultimate of joys. Life should be about bringing hope, peace, vision... a sense of purpose beyond yourself.
