Article Abstract

The remarkable impact of mRNA vaccines on mitigating disease and improving public health has been amply demonstrated during the COVID-19 pandemic. Many new mRNA-based vaccine and therapeutic candidates are in development, yet the current reality of their stability limitations requires their frozen storage. Numerous challenges remain to improve formulated mRNA stability and enable refrigerator storage, and this review provides an update on developments to tackle this multi-faceted stability challenge. We describe the chemistry underlying mRNA degradation during storage and highlight how lipid nanoparticle (LNP) formulations are a double-edged sword: while LNPs protect mRNA against enzymatic degradation, interactions with and between LNP excipients introduce additional risks for mRNA degradation. We also discuss strategies to improve mRNA stability both as a drug substance (DS) and a drug product (DP) including the (1) design of the mRNA molecule (nucleotide selection, primary and secondary structures), (2) physical state of the mRNA-LNP complexes, (3) formulation composition and purity of the components, and (4) DS and DP manufacturing processes. Finally, we summarize analytical control strategies to monitor and assure the stability of mRNA-based candidates, and advocate for an integrated analytical and formulation development approach to further improve their storage, transport, and in-use stability profiles.

The implementation of 3D printing technologies in clinical settings depends on formulations that are not only printable and compliant with quality standards but also physicochemical stable and reliable under real-use conditions. This study evaluated the in-use and long-term physicochemical and rheological stability of two hydrogel inks developed for semisolid extrusion (SSE) 3D printing: one containing pimobendan (PBD) and the other a placebo. PBD is a poorly water-soluble drug used to treat canine heart failure, whose formulation challenges highlight the potential of personalised drug delivery.

Insulin stability is a critical yet underexplored factor affecting diabetes outcomes in Sub-Saharan Africa (SSA). High ambient temperatures, unreliable refrigeration, and weak regulatory oversight may compromise insulin quality during storage and use. Patients often rely on traditional, non-validated methods that risk potency loss.

Dissolution and stability of vigabatrin powder in water, fruit juice, milk, and infant formula.

The prescribing information for the antiseizure medication Vigadrone® (vigabatrin) Powder for Oral Solution advises only reconstituting the powder in water prior to administration and discarding unused solution. However, caregivers may seek to reconstitute vigabatrin in a pediatric patient's preferred liquid rather than water to ease administration. We performed an in-use dissolution and stability study of vigabatrin powder reconstituted in 4 liquids-water, apple juice, whole milk, and infant formula-with testing performed 0, 24, and 48 h after preparation with storage at 2-8 °C in a capped, glass container.

() is a highly detrimental avian pathogen that has resulted in substantial economic losses within the global poultry industry. The existing vaccines, presently in use, fail to offer comprehensive protection. The objective of this study was to create recombinant attenuated vaccine (RASV) strains, namely rSC0130(pS-rRS01790), rSC0130(pS-rBMP), rSC0130(pS-rGrpE), rSC0130(pS-rRS00900), and rSC0130(pS-rRS00275), expressing RS01790, BMP, GrpE, RS00900, and RS00275 proteins, and verify their protective effects.

Cross-linked polyurethane is widely used as a high-performance elastomer, owing to its excellent mechanical properties and superior durability. However, a critical challenge remains in integrating its in-use stability with dynamic behavior during recycling. Herein, supertough and multirecyclable cross-linked polyurethanes were developed through the cooperation of supramolecular chain extenders and noncovalent cross-linkers.
