WebInter-dose AUC (ie, most generally AUC 0–12 h) is more informative than C 0 because it correlates better with rejection in patients with kidney transplants [16–18]. However, AUC 0–12 h estimation based on a complete pharmacokinetic profile requires multiple blood samples over a 12-h period, which is uncomfortable for the patient and costly. Web) found that teicoplanin C trough was correlated with dose/kg on the second or third day of therapy, and with dose/kg, age and CL cr on the fourth day of therapy. In their study, the mean C trough was 15.3 mg/L and the range was 4.9-36.3 mg/L. In the present study, 28/112 (25%) of the teicoplanin C trough measurements were <10 mg/L

WebIn your example if you measured a peak and trough and the AUC is ~500 with a trough of 12 then yes, if the trough is stable the AUC is pretty stable, expect only small fluctuations. For your obese patient if q8h dosing is ok then 1250mg q8h would decrease the AUC proportionally to 558 and the trough would increase to ~15.

WebC trough and AUC 24 using either ref or EqA were correlated more closely (r 2 = 0.94) than with EqB (r 2 = 0.86). Assuming a vancomycin MIC of 1 mg/L, an AUC 24 ≥400 mg⋅h/L was targeted.
