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.
Almac has developed a flexible paediatric dosage form consisting of minitablets filled into stickpacks using a robust manufacturing and filling process suitable for routine commercial manufacture.
Compression tooling and tablet press manufacturers are faced with ongoing challenges in the tablet manufacturing environments. Providing support in all aspects of the tablet compression process should be expected from your tooling and tablet press partner. These services should include: press operator training, maintenance/calibration services, quick delivery of replacement parts, tooling, tablet design and powder formulation support.
To demonstrate the process by which a placebo formulation was designed for an oral solid dose product that would be dispensed to the patient as a fast-dissolve tablet. The tablet is added to water and the resulting solution is dosed as a antibiotic mouthwash. Placebo matching was required not only for the tablet but also for the solution which the patient took.
In this case study, API (X) is a highly insoluble compound with a particle size of approximately 14 microns and targeted as a powder for oral suspension dosage form.
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.
