Exposure following oral inhalation depends on the deposition pattern of the inhaled aerosol, the extent and rate of oral and pulmonary absorption, as well as systemic distribution and clearance.
Comprehensive QSRR modeling as a starting point in characterization and further development of anticancer drugs based on 17α-picolyl and 17(E)-picolinylidene androstane structures.
The selection of the most promising anticancer compounds from the pool of the huge number of synthesized molecules is a quite complex task.
Application of Physiologically Based Absorption Modeling to Characterize the Pharmacokinetic Profiles of Oral Extended Release Methylphenidate Products in Adults
A previously presented physiologically-based pharmacokinetic model for immediate release (IR) methylphenidate (MPH) was extended to characterize the pharmacokinetic behaviors of oral extended release (ER) MPH formulations in adults for the first time.
