HHS Awards $97-Million Vaccine Development Contract

The principles of direct compression haven’t changed in more than a century. So why can the topic still pack a ballroom?

X-ray microtomography has great potential for improving the understanding of the structural features of solid dosage forms and the changes in those features during manufacturing, handling, and storage.This article describes the basic principles of the technique and provides examples of its potential applications.

An increasing number of new compounds are being introduced into pharmaceutical pilot plants.The knowledge base for these compounds regarding their toxicities,physical handling, and cleaning is limited.The authors examine various approaches for addressing the cleaning validation of new compounds and discuss the role of determining appropriate visible residue limits.

To meet the requirements of the USP ^755& Minimum Fill and ^698& Deliverable Volume tests, target fill levels greater than 100% must be established.This article proposes a criterion for establishing an appropriate target fill level such that a sample will have a 95% probability of passing these USP tests at 95% confidence.

The authors argue that chlorine dioxide (CD) is a safe and effective decontaminating agent that can be used for challenging applications.The effectiveness of CD gas for sterilizing complex isolator systems is studied.

The authors study the effects of sweet potato and cocoyam starches on the compressional and mechanical characteristics of a paracetamol tablet formulation using cornstarch BP.

Innovators and generics makers are staking out positions on follow-on proteins and other manufacturing issues.
