Particles, whether visible or sub-visible, in a drug product are a very serious concern (e.g., obstruction of blood vessels, inducement of immunogenicity). Particles may result from external sources (e.g., dust), manufacturing (e.g., silicone oil), or interaction with the container/delivery systems (protein aggregates). This section presents papers on particle measurement, management and resultant effects.
