Now, the AUC can be calculated. Commonly, the trapezoidal rule is used to calculate the AUC by hand.

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 WebPer the latest guidelines, AUC-based monitoring is preferred over trough-based monitoring as the most accurate and optimal way to manage vancomycin dosing.

WebJan 5, 2024 · Logistic Regression belongs to the family of generalized linear models. It is a binary classification algorithm used when the response variable is dichotomous (1 or 0). Inherently, it returns the set of probabilities of target class. But, we can also obtain response labels using a probability threshold value. 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.

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.
