Application of Bayesian estimation for the prediction of an appropriate dosage regimen of amikacin.

abstract：:Increasing costs of research and development in the pharmaceutical industry has necessitated a growing interest in the early prediction of human pharmacokinetics of drug candidates. Of growing interest is the need to understand oral absorption, the most common route of small molecule drug administration. The fraction ...
