A Pharmacokinetic and Safety Evaluation of Single Oral Doses of Eszopiclone in Pediatric Subjects from 6 to 17 Years of Age with Attention Deficit Hyperactivity Disorder and Insomnia

Conference: American Academy of Child & Adolescent Psychiatry (AACAP)

Eszopiclone is a single-isomer, nonbenzodiazepine, cyclopyrrolone agent that has demonstrated efficacy with both polysomnography (PSG) and patient-reported measures in non-elderly adults with chronic primary…

It’s not gloom and doom if it helps to frame the problem.

It’s not gloom and doom if it helps to frame the problem.

I know, I know — you don’t want to read another doom and gloom blog. But, in a recent article in the National Review* (link is no longer available), Peter Thiel does an excellent job of linking the desperate necessity of advancements in technology and science with the broader societal crises we are now experiencing. Thiel posits that there is a mistaken, but nearly universal, background assumption about easy progress that underlies our unwillingness to tackle difficult problems.

Transporter-Based in vitro-in vivo Extrapolation (IVIVE)

Conference: ISSX
Software: GastroPlus®
Division: PBPK

The use of in vitro data to predict the pharmacokinetics (PK) of drugs whose disposition is mediated by transporters is complicated due to unknown transporter expression levels in individual tissues both…
