Modeling of In-use Stability for Tablets and Powders in Bottles

November 28, 2016
#Customer Presentation/ Publications using ASAPprime®

A model is presented for determining the time when an active pharmaceutical ingredient in tablets/powders will remain within its specification limits during an in-use period; that is, when a heat-induction sealed bottle is opened for fixed time periods and where tablets are removed at fixed time points. This model combines the Accelerated Stability Assessment Program […]

Improved Protocol and Data Analysis for Accelerated Shelf-Life Estimation of Solid Dosage Forms

November 23, 2016
#ASAPprime® and Stability Modeling

The concept of an isoconversion paradigm, where times in different temperature and humidity-controlled stability chambers are set to provide a critical degradant level, is introduced for solid-state pharmaceuticals. Reliable estimates for temperature and relative humidity effects are handled using a humidity-corrected Arrhenius equation, where temperature and relative humidity are assumed to be orthogonal. Imprecision is […]

#ASAPprime® and Stability Modeling #Customer Presentation/ Publications using ASAPprime®

In the Handbook of Stability Testing in Pharmaceutical Development, Dr. Ken Waterman discusses how products are assigned a shelf-life which determines the time when a product is considered safe and effective under a relevant storage condition.  A number of factors are used to assign that shelf-life.

The Application of the Accelerated Stability Assessment Program (ASAP) to Quality by Design (QbD) for Drug Product Stability

November 22, 2016
#ASAPprime® and Stability Modeling

An isoconversion paradigm, where times in different temperature and humidity-controlled stability chambers are set to provide a fixed degradant level, is shown to compensate for the complex, non-single order kinetics of solid drug products. A humidity-corrected Arrhenius equation provides reliable estimates for temperature and relative humidity effects on degradation rates. A statistical protocol is employed […]

Accelerated Stability Modeling for Peptides: a Case Study with Bacitracin

November 21, 2016
#ASAPprime® and Stability Modeling

The Accelerated Stability Assessment Program (ASAP) was applied for the first time to a peptide, the antibiotic active pharmaceutical ingredient bacitracin. Bacitracin and its complex with zinc were exposed to temperature and relative humidity conditions from 50 to 80°C and from 0 to 63% for up to 21 days. High-performance liquid chromatography was used to […]
