- Daptomycin Transmembrane Clearance by Continuous Venovenous Hemodialysis [ Time Frame: From time of daptomycin administration to 48 hours post dose when subjects were also receiving continuous venovenous hemodialysis ]Quantifies the rate of daptomcyin removal by continuous venovenous hemodialysis.
- Daptomycin Dose Actually Administered [ Time Frame: Time of daptomycin administration ]
- Observed Daptomycin Peak Serum Concentration [ Time Frame: At the end of the daptomycin intravenous infusion (at approximately 30 minutes) ]The maximum concentration of daptomycin in the body after receiving a dose of the drug. This was determined at the end of the daptomycin intravenous infusion at approximately 30 min.
- Daptomycin Volume of Distribution at Steady State [ Time Frame: From time of daptomycin administration to 48 hours post dose ]Volume of distribution quantifies the distribution of daptomycin between the blood and the rest of the body. The greater the volume of distribtion, the greater the extent of daptomycin distribution throughout the body.
- Daptomycin Total Body Clearance [ Time Frame: From time of daptomycin administration to 48 hours post dose when subjects were also receiving continuous venovenous hemodialysis ]Total body clearance represents the rate at which daptomycin is removed from the body. In patients treated with continuous venovenous hemodialysis, the major pathways of daptomycin removal likely are: removal by continuuous venovenous hemodialysis (transmembrane clearance) and breakdown by the liver.
- Daptomycin Half-life [ Time Frame: From time of daptomycin administration to 48 hours post dose when subjects were also receiving continuous venovenous hemodialysis ]Half-life describes the time it takes for the concentration of the daptomycin in the body to decrease by one half.
- Daptomycin Free Fraction [ Time Frame: From time of daptomycin administration to 48 hours post dose ]In the body, daptomcyin may be bound to proteins in the blood or it may not be bound to any proteins (also as the "free" component.) Free fraction describes the percent of daptomycin that is unbound or free. The unbound portion of daptomycin is able to kill bacteria.
