Where will tomorrow’s drug delivery opportunities come from? Advances in science and technology are opening the door for innovative treatment options and novel delivery mechanisms. At the same time, the integration of advanced analytics and sensor technologies is enabling the development of drug delivery devices that are smarter, more automated, and more connected than ever before.
Tablet land is the narrow, horizontal surface perpendicular to the tablet’s periphery, which creates a junction between the tablet’s periphery and cup. The three primary reasons for incorporating a land into a tablet’s design are to increase the strength of the punch edges, increase the wear characteristics of the inner edge of the punch cup, and reduce the severity of nicks on punch edges.
To improve the suspendibility of a water- insoluble active pharmaceutical ingredient (API) in a sorbitol- based reconstitutable powder for oral suspension formulation using two novel excipients Sentry™Polyox™WSR N80, NF (polyethylene oxide) and Avicel CL-611® NF (microcrystalline cellulose/carboxymethylcellulose sodium).
Rapid and consistent in-vivo drug dissolution is critical for drug absorption. In-vitro dissolutions tests are used to predict in-vivo disintegration and dissolution properties of drug products. The in-vitro disintegration and dissolution times of tablets and capsules can vary significantly based on their composition and processing.
As stated in the International Conference on Harmonisation Harmonised Tripartite Guidance on Pharmaceutical Development, ICH Q8 (R2), “The aim of pharmaceutical development is to design a quality product and its manufacturing process to consistently deliver the intended performance of the product.”1 Several tools are available as guidance issued by FDA such as “Quality Systems Approach to cGMP Manufacturing”2 that includes ideas such as Quality by Design (QbD) in the development process. This guidance, amongst others, lay the framework for expectations of regulatory reviewers in their examination of client submittal documentation.
The pharmaceutical industry has undergone a sea of change in recent years as manufacturers have adapted to the end of the era of large-volume production of mass-market blockbuster drugs. With firms now focusing in on subpopulations of patients, there is a need for lean, adaptable facilities that can switch quickly between multiple products in multiple formats. Modular facilities can meet this need. While not a panacea, for the right project characteristics, ‘Modularity in Design’ can deliver significant and quantifiable long-term value.
Porosity is a characteristic that influences many of the critical quality attributes of finished pharmaceutical products. Porosity can help predict deformation properties during compression, pharmacokinetic behavior within the body, shelf life, moisture penetration, and bioavailability.
