Vancomycin – Timing of next dose based on est. Ke value
Vancomycin – Timing of next dose based on est. Ke value
Vancomycin -Timing of next dose based on estimated Ke value
This program can be used to determine when to administer the next dose of vancomycin after a supratherapeutic trough is obtained. An estimated elimination rate constant is generated from the creatinine clearance which is then used to determine the timing of the next dose based on the desired target trough concentration.
(Note: if the vancomcyin level is drawn early and you want to estimate the actual trough just before the next dose to determine if the current regimen is appropriate -
use the following program
.)
Estimated creatinine clearance
:
(mL/min)
Current trough
:
mcg/mL
Desired trough target (lower concentration)
:
mcg/mL

Trough Calculators
Allows the user to estimate the actual (extrapolated) trough based on the elimination rate constant and the number of hours the level was drawn before the next scheduled dose. A supratherapeutic level may be actually therapeutic if it was drawn just before the next dose.

If you would like to enter the time since the last dose was given, use this version. This new version may be especially useful if the trough was drawn late and thenext dose was delayed. Example: current regimen vanco 1 gram q12h. Trough wasdrawn 12.5 hours after the last dose.
Vancomycin single-level – dose infused early or late
The GlobalRPh vancomycin single-level calculator uses the Vd recommended in Bauer’s text: 0.7 L/kg. Use the advanced version if you wish to manipulate this value.
