Pharmaceutical companies conduct stability studies to characterize the degradation of drug products and to estimate drug shelf life.

To determine the shelf life of new medicinal products, long-term stability studies are conducted of at least three registration batches at multiple storage conditions. It is common practice to perform a statistical analysis on the resulting data separately for each storage condition. Although this is a straightforward approach to evaluating the data at each condition, the opportunity exists to combine all of the storage conditions into one single combined analysis that yields benefits without compromise to the estimation of the effect of each storage condition separately. Present external guidance provides little or no direction on treating multiple storage conditions in one combined statistical analysis. Because it has been underexposed in literature, this article presents a combined analysis, and discusses in detail the use of initial results, the imposed restrictions on batch intercepts, and poolability of batches across storage conditions. A case study is presented to demonstrate the differences with an analysis per storage condition and to show the advantages with respect to shelf life estimation.

This book provides a comprehensive and unified presentation of the principles and methodologies of design and analysis of stability studies. The text is well-written and provides a well-balanced summary of current regulatory perspectives. The primary SAS programs macros -comprising STAB-for estimating the expiration dating period of a drug product based on linear regression analysis are listed in the Appendix B and these macros help to reinforce the theory presented in the text. Its clear explanation, plentiful illustrations, moderate mathematical exposition, and inclusion of SAS programming codes make all the materials accessible to most of the applied statisticians working in the biopharmaceutical environment.

ME TOO, что означало: Я. Беккер расхохотался. Он дожил до тридцати пяти лет, а сердце у него прыгало, как у влюбленного мальчишки. Никогда еще его не влекло ни к одной женщине. Изящные европейские черты лица и карие глаза делали Сьюзан похожей на модель, рекламирующую косметику Эсте Лаудер. Худоба и неловкость подростка бесследно исчезли.
