In 2014, the contract manufacturing market for solid dosage forms is anticipated to be $19.6B, representing 58% of the total CMO market value of $33.7B. While the market value percentage for solid dose has been drifting downward — likely related to the shift towards biologics, which are more expensive to develop and manufacture — the propensity to outsource oral solid dosage forms continues to grow modestly.
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.
<p>Excipients are often described as inactive ingredients that assist in the delivery and processing of the active pharmaceutical ingredients. Although this is true, excipients have a much larger influence on final product performance than the term “inactive ingredient” suggests. In fact, choosing the right excipients is a key determinant of the quality and functionality of a pharmaceutical product.</p>
A common problem statement in the pharmaceutical industry is low oral bioavailability of drug candidates with poor aqueous solubility. The literature suggests that a significant majority of new drug candidates are in the Biopharmaceutics Classification System (BCS) class II and IV space, which includes compounds that are dissolution rate, solubility or permeability limited to absorption, or all three. As portfolios across the industry are increasingly focused on these compounds, the need for enabling technologies continues to grow.
