Vancomycin - Predicted Trough Value - Level drawn early
This program can be used to determine if the current regimen is appropriate based on an early (supratherapeutic) vancomycin level which is used along with an estimated elimination rate constant to determine the level just before the next dose.
(Note: if a random supratherapeutic vancomcyin level is drawn and you need to determine when to give the next dose based on a desired target trough level -
use the following program
. Overview: 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 target trough concentration.)
Estimated creatinine clearance
Current trough (early supratherapeutic value)
Number of hours trough was drawn PRIOR to next dose
(Note: may use decimals e.g. 3.5 hrs. This time will be used to calculate the estimated trough value just before the next dose is due.)

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.
Trough drawn early? -Estimation Tool based on entered Kel
This new 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.

Use this program 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

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.

The NewMedicalTerms 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.
