A set of reference compounds for time-dependent inhibition (TDI) of cytochrome P450 with available literature data for kinact and KI was used to predict clinical implications using the GastroPlusTM software.
A Survey of the Regulatory Requirements for BCS-Based Biowaivers for Solid Oral Dosage Forms by Participating Regulators and Organisations of the International Generic Drug Regulators Programme
The Biopharmaceutics Classification System (BCS) based biowaiver is a scientific model which enables the substitution of in vivo bioequivalence studies with in vitro data as evidence of therapeutic equivalence subject to certain conditions.
Discovery PBPK: How to enhance the expected accuracy of bioavailability predictions for NCEs that are not primarily metabolized
In this webinar, we will review the accuracy of purely in silico estimates of bioavailability and the chemistry classification of new chemical entity (NCE) molecules that are easier or harder to...
Experimental versus theoretical log D7.4, pKa and plasma protein binding values for benzodiazepines appearing as new psychoactive substances
The misuse of benzodiazepines as new psychoactive substances is an increasing problem around the world. Basic physicochemical and pharmacokinetic data is required on these substances to interpret and predict their effects upon humans.
