This article explores the impact of test volume, microbial distribution, and dilution errors on bioburden testing variability. It presents statistical approaches to estimate percentage error and discusses strategies to optimize microbial enumeration techniques in biopharmaceutical quality control.
There is a great need for sensitive, precise, and easily accessible analytical detection techniques for protein sequencing.
Evaluating Progress in Analytical Quality by Design
The authors present the results of a survey of small- and large-molecule pharmaceutical and biopharmaceutical companies on implementation of Analytical quality by design concepts.
Improving the Dissolution of Poorly Soluble APIs with Inorganic Solid Dispersions
April 1st 2017Solid dispersions based on organic polymers can have stability issues. Inorganic solids, especially those based on silica chemistry, may be suitable alternatives to organic polymers due to their pre-formed pore system, high absorptivity, and commercial availability in pharmaceutical quality. Mesoporous granulated colloidal silicon dioxide has been studied with class II and IV actives of the Biopharmaceutics Classification System for its ability to improve dissolution. Using suitable formulation strategies, the dissolution of these APIs could be significantly increased. The absorption of poorly soluble APIs onto silicon dioxide can, therefore, be considered a viable formulation path to overcome solubility challenges.
