Subvisible particles generated during the preparation or administration of biopharmaceuticals might increase the risk of immunogenicity, inflammation, or organ dysfunction. This study compared the impact of two infusion systems, peristaltic movement and gravity-based, on the level of subvisible particles using intravenous immunoglobulin as a model drug. The results showed that the peristaltic pump was more susceptible to particle generation, while the gravity infusion set with an in-line filter contributed to particle reduction.
Subvisible particles generated during the preparation or administration of biopharmaceuticals might increase the risk of immunogenicity, inflammation, or organ dysfunction. To investigate the impact of an infusion system on the level of subvisible particles, we compared two types of infusion sets based on peristaltic movement (Medi-fusion DI-2000 pump) and a gravity-based infusion system (Accu-Drip) using intravenous immunoglobulin (IVIG) as a model drug. The peristaltic pump was found to be more susceptible to particle generation compared to the gravity infusion set owing to the stress generated due to constant peristaltic motion. Moreover, the 5-& mu;m in-line filter integrated into the tubing of the gravity-based infusion set further contributed to the reduction of particles mostly in the range & GE; 10 & mu;m. Furthermore, the filter was also able to maintain the particle level even after the pre-exposure of samples to silicone oil-lubricated syringes, drop shock, or agitation. Overall, this study suggests the need for the selection of an appropriate infusion set equipped with an in-line filter based on the sensitivity of the product.
