Sample problem to aid filling out the table above
Patient is receiving Gentamicin 120mg IVPB q8h. Infusion time is 30 minutes. A peak is drawn 1 hour after the
start
of the infusion and a trough is drawn 5 hours after the
start
of the infusion (note the entries below). The program will take into account the infusion time when calculating the actual peak (do not subtract the infusion time from the number of hours post dose). This program assumes that information provided is based on steady state. If you were to calculate these values by hand, the actual Cmax would occur at the end of the infusion. In this example (t)= 1- 0.5 = 0.5. The Cmin calculation would use a time value of (8 - 5 = 3 hours).
