A paper has highlighted a drug product quality assurance programme for personalised preparations, including application of a preventive or corrective measures (CAPA) system.
While determining active intakes and control strategies for short chain alkyl N-nitrosamines was relatively easy to establish, nitrosamine drug substance-related impurities continue to present challenges. Here, Dave Elder reflects on the three main instances of nitrosamine contamination in drug products.
A team of American scientists report on some recent developments in the realm of pharmaceutical stress testing, or forced degradation, practices relating to solid dosage forms, bringing some valuable clarity for drug developers.
Dr Kiren Baines, Analytics Lead at eXmoor Pharma, details some of the critical steps when validating an assay or analytical method, including key considerations for developing an experimental plan aligned with ICH guidelines.
The valsartan nitrosamine contamination issue was probably the most significant quality issue to hit the pharmaceutical industry in a decade. Here, Dave Elder outlines how agencies and manufacturers are dealing with the problem and indicates the knowledge gaps that might be concealing future complications.
Here, Dave Elder discusses the determination of less than lifetime (LTL) limits for highly potent N-nitrosamine compounds and how to ensure safety in dosing.
Glycosylation of therapeutic proteins is important to biologic drug development and is a critical quality attribute that is monitored during manufacturing. Analysis of O-glycans is technically challenging compared to that of N-glycans. In this review, Xiaofeng Shi, Saulius Vainauskas and Christopher H Taron summarise current O-glycan analytical approaches, describe the…

Reducing unnecessary regulatory burden relating to excipients is important for any pharmaceutical manufacturer. In this article, Sunil Kumar Nataraj, Bastiaan Dickhoff and Kalyan Janjanam discuss a rational basis for controlling and specifying conflicting excipient attributes to avoid potentially tedious and complex regulatory processes.
There are significant interpretational differences between the European Medicines Agency (EMA) and US Food and Drug Administration (FDA)’s guidance on active pharmaceutical ingredient (API) starting materials. In this article, Dave Elder explores the ambiguity in guidance from both agencies and addresses why industry struggles to identify and justify starting materials…
