Patient data is as follows: Ht = 69 in. Wt = 70.5 kg. Scr = 1.33 mg/dL.
The following represent the dosing history:
Based on the following doses and serum concentrations, calculate the following: ke, t1/2, Vd, CL, infusion dose (round down to the nearest 10 mg) over 1 hr, dosing interval (round up to the nearest 12 hr), projected Cpmaxss and Cpminss with target Cpmaxss = 9 mg/L and Cpminss = less than 1 mg/L and time from the last sample to starting the next dose (to the nearest hour).
|Date||Time||Dosage||Infusion Duration||Serum Concentration|
|09/17/15||0900||180 mg||1 hr|
|09/17/15||2100||180 mg||1 hr|
|09/18/15||0900||180 mg||1 hr|
|09/18/15||2100||180 mg||1 hr|
|09/19/15||0900||180 mg||1 hr|
|09/19/15||2100||180 mg||1 hr|
