Certara’s Best of Blogs 2016
A selection of short essays from our blog, written to empower our customers with modeling and simulation (M&S) and regulatory writing solutions in order to help them solve the toughest drug development problems. Certara staff contributions range in topic from pharmacometrics to systems biology to the growing importance of regulatory writing and sharing clinical trial results.
Read MoreQuantitative Pharmacology Strategies for Pediatric Drug Development
Pediatric patients are not simply small adults. Children differ from adults in both disease pathophysiology and pharmacokinetics/pharmacodynamics (PK/PD). Yet historically, 80 percent of medicines used in children had little to no data guiding prescribers on proper use. In this blog post, I’ll discuss the challenges of developing drugs for children and explain how quantitative pharmacology […]
Read MoreEarly Development and Translational/Quantitative Pharmacology Strategies in Pediatric Drug Development
This seminar described the application of early development strategies to enable development in children, in cases where limited adult data are available. Extensive use of translational science and quantitative modeling and simulation methods are key underpinnings to facilitate the successful execution of these programs.

Impact of Low-dose Ritonavir on Danoprevir Pharmacokinetics: Results of Computer-based Simulations and a Clinical Drug-drug Interaction Study
Danoprevir, a potent, selective inhibitor of the hepatitis C virus (HCV) NS3/4A protease, is metabolized by cytochrome P450 (CYP) 3A. Clinical studies in HCV patients have shown a potential need for a high danoprevir daily dose and/or dosing frequency. Ritonavir, an HIV-1 protease inhibitor (PI) and potent CYP3A inhibitor, is used as a pharmacokinetic enhancer […]
