Addressing the needs of the geriatric population
Q: What role can excipients and dosage forms play in addressing the challenges of treating geriatric patients?
A: Alen Guy, IMCD Group says:
We're all getting older, of course, but worldwide the percentage of people aged 65 and older will grow from 528 million in 2010 to about 1.47 billion in 2050 . Furthermore, people in that age cohort, who now use 30 to 50 percent of prescriptions, will use 60 to 90 percent of them by 2050 . That makes sense when you consider that someone 55 years old has, on average, 2.68 chronic conditions . By the time this person is older than 65, the average reaches 5 chronic conditions . In addition, nearly 40 percent of the elderly suffer from arthritis and another serious health condition, such as cardiovascular disease or diabetes .

Dust containment for tablet manufacturing
Q: What should my company look for in a dust containment system?
A: Luca Di Siervi, Nilfisk says:
High-potency APIs (HPAPIs) continue to be one of the fastest-growing segments in pharma. According to a recent report by Grand View Research, the global market for HPAPIs will reach 34.8 billion by 2025 .
Because HPAPIs are highly toxic, they require a higher level of containment to keep operators safe and also prevent cross-contamination. As a result, my company has seen a growing number of requests for dust containment systems as opposed to the standard filter systems commonly used in the production of less-toxic pharmaceuticals.
Effect of HPC molecular weight on granules and tablets prepared by two wet granulation methods
Berna Ehlig, Edmont Stoyanov, and Wade Tanev, Nisso
In this article, researchers from Nisso present the results of a study that examined how the molecular weight (MW) of different hydroxypropyl cellulose (HPC) grades affected the characteristics of granules and tablets prepared by two wet granulation methods: high shear and fluid bed.
Wet granulation is one of the most commonly used methods of developing solid dosage drug products. Among the advantages of this classical granulation method over other technologies are a narrow particle size distribution (PSD) of the granules, few fine particles that yield little dust, more consistent powder flow, better control of granule size, very good binder homogeneity, and good powder compactability.
The most important excipient group in a successful wet granulation formulation is the binder. Within this group are polymers with different chemistries, mechanical properties, and viscosity ranges. The polymer binder HPC has attracted the attention of formulators in the last decade due to its superior mechanical properties, chemical stability, and multi-functionality. This cellulosic ether appears to work even in challenging formulations with high-dose, poorly compressible drug products, where other binders usually fail. Low-viscosity (low-MW) HPC grades are used as a binder for all types of wet granulation including high-shear, fluid-bed, extrusion, and melt granulation. To select the suitable grade, scientists often must conduct many experiments, adjusting the desired powder and tablet characteristics. In this study, we focused on the influence of the HPC MW on the granule and tablet characteristics in fluid-bed and high-shear wet granulation.

Multiparticulates add important functions to solid dosage formulations. They provide reliable drug delivery, reduce the potential for abuse, and supply a platform for high-potency combination products. Made using conical rotor technology, these very small beads can also carry a large amount of API. That allows a given dose to be delivered in small tablets and capsules, which promotes patient compliance. Compact API loading also facilitates combination products because it allows two or more APIs to fit in an envelope that previously could hold just one. Conical rotor technology offers an economical method of producing multiparticulates.
