Rat pharmacokinetic studies are commonly utilized in early discovery to support absorption, distribution, metabolism, and excretion optimization of active pharmaceutical ingredients (APIs). The aim of this work was to compare exposures from fit-for-purpose oral suspension and solution formulations in rats to guidance provided by the refined Developability Classification System (rDCS) with respect to identifying potential limits to oral absorption, formulation strategy selection, and to optimize oral bioavailability (BA). This investigation utilized six diverse APIs covering a large range of biorelevant solubility, metabolic stability, and oral BA in rats.

We employed ecological momentary assessment and intervention through ReApp, a mobile app designed to train and promote PCR. We analyzed data from the intervention group of a randomized controlled trial with a total of 100 participants who used ReApp for three weeks.

People exhibit an extraordinary capacity to adjust to stressful situations. Here, we argue that the acute stress response is a major driving force behind this adaptive process. In addition to immediately freeing energy reserves, facilitating a rapid and robust neurocognitive response, and helping to reinstate homeostasis, the stress response also critically regulates neuroplasticity.
