Q

Vanco dosing

A
  1. old school (trough based; figure out Cl)
  2. AUC (non-Bayesian) - use peak/trough to calculate AUC
  3. AUC (Bayesian) -obtain random sample and previous knowledge and combine to get Cl

Q

Trough based dosing problems

A

Without the peaks there is no way to know what the area is exactly (neglects the area from the infusion)
