The Rise
Over the past decade, they have become increasingly common in healthcare. Where traditional vials and glass syringes were once standard, they now dominate the delivery of many injectable drugs. Several factors have contributed to the rise of Prefilled Syringes, including improvements in filling technologies, drug stability requirements, and a push for enhanced patient safety. They offer notable advantages over traditional vials and syringes. With a prefilled syringe, the drug is already contained in the syringe, ready for administration. This eliminates steps associated with drawing up medication from a vial using a separate syringe. They help reduce medication errors by eliminating dosing mistakes related to drawing up drugs. They also improve stability for many sensitive biologic drugs that may degrade with multiple entries into vial stoppers. Enhanced Safety and Control Patient safety has been a major driver behind the increased use of prefilled syringes. With traditional vials and syringes, there are more opportunities for dosing errors between drawing up and administering the drug. They remove steps where mistakes can occur, like drawing up the wrong drug or wrong dose. From a manufacturing perspective, prefilling syringes also enhances control over fill volumes and avoids over- or underfilling that can occur when filling syringes manually. Automated filling technology is able to fill syringes with exceptionally high reproducibility and control compared to manual methods. This reduces variation in drug doses delivered and improves dosage accuracy. Improved Use Experience and Convenience The convenience of prefilled syringes is a significant advantage for both healthcare providers and patients. With all standard safety features like needle guards built-in, prep and administration can take just a few simple steps. This streamlines the use process compared to traditional vials and syringes. For patients, they minimize the number of steps required when self-injecting. They offer a ready-to-use format that does not require drawing up medication or air bubbles prior to injection. This simplified experience can help encourage medication adherence, especially for sensitive biologic drugs requiring frequent administration. Challenges with Syringe Systems While prefilled syringes demonstrate clear benefits, they also present unique manufacturing and quality hurdles compared to traditional vials. Tight syringe tolerances require more precise filling equipment and processes to fill syringes reproducibly without defects. Issues like leakage, trapped air or medication adhering to the syringe walls can impact quality if not addressed. Compatibility between the drug formulation and syringe components is also critical. Leachables and extractables from syringe materials like rubber stoppers or coating delamination must not interfere with drug stability or safety. Comprehensive testing and validation studies are necessary to establish syringe systems for new drugs. Looking Ahead with Combination Products As they continue to rise in popularity, combination product innovations are expanding their capabilities. Technologies are being explored to incorporate features like sensors, connected health functions oreven automated injection mechanisms into prefilled syringe platforms. One example is Novartis’ dry powder inhaler integrated with a prefilled syringe containing a liquid component. The syringe automatically times injection of the liquid as the patient inhales, synchronizing delivery of the dual components. Combination systems like these could help improve treatments that currently require multiple delivery devices by streamlining administration in a single, integrated device. Prefilled syringes have established themselves as a preferred delivery method in modern medicine thanks to enhanced safety, control, convenience and compatibility with sensitive biologic drugs. Though manufacturing challenges remain, ongoing refinements are expanding the utility of prefilled syringes and combination product integration is opening new frontiers for their application. With continued adoption, prefilled syringes will likely play an increasingly important role supporting patient-centered care into the future.
