Particulate matter in injectable drug products.

Unlabelled: Clinicians have had concerns about particulate matter contamination of injectable drug products since the development of the earliest intravenous therapeutics. All parenteral products contain particulate matter, and particulate matter contamination still has the potential to cause harm to patients. With tens of millions of doses of injectable drug products administered in the United States each year, it is critical to understand the types and sources of particulate matter that contaminate injectable drug products, the possible effects of injected particulate matter on patients, and the current state of regulations and standards related to particulate matter in injectable drug products. Today, the goal of manufacturers, regulators, and standards-setting organizations should be to continue to minimize the risk of particle-induced sequelae, especially in high-risk patients, without trading unnecessary manufacturing burden for minimal safety gains.

Lay Abstract: All injectable drug products are contaminated with some level of solid particulate matter, including, for example, fibers, dust, rubber, and silicone. These materials enter drug products primarily during the manufacturing process. The possible effects on patients of injectable drug products containing particulate matter depend on a number of factors. However, given the large number of patients receiving injectable drug products each year in the United States and the potential for particulate matter to cause harm to patients, it is critical to continue to minimize particulate matter contamination in injectable drug products. Manufacturing standards and regulations have helped improve manufacturing quality. Nevertheless, manufacturers, regulators, and standards-setting organizations must continue to work toward improving manufacturing quality and minimizing the risk of harm from particle contamination, especially in high-risk patients.
