Self-Injection Made Easy

3mL cartridges are proven containers to deliver your larger-volume biologics injections. Pii’s 3mL cartridge kit improves patient compliance by supporting a range of therapies that require frequent injections and variable dosing.

Ready-to-Use 3mL Cartridge-Based Is Ideal for High Volume, High Viscosity, Complex Injectables

The combination of an aging population and more people suffering from chronic diseases is making it difficult for healthcare professionals to effectively treat patients over the long-term, subsequently impacting patient compliance. This has led to increased demand for patient-friendly administration systems, such as single-and dual-chamber cartridges. In fact, industry gurus estimate the global autoinjectors market, which includes cartridge-based systems, to be valued at more than $6.2 billion by 2027.1

Surpasses Injection Volume Limitations

The ready-to-use (RTU) 3mL cartridge-based, single-use is specifically designed to ensure consistency of delivery for high-volume, high-viscosity injectable drug delivery systems.

According to the National Center for Biotechnology Information, subcutaneous (SC) delivery of biologics has traditionally been limited to fluid volumes of 1–2 mL, with recent increases to volumes of about 3mL. This injection volume limitation poses challenges for high-dose biologics, as these formulations may also require increased solution concentration in many cases, resulting in high viscosities which can affect the stability, manufacturability, and delivery/administration of therapeutic drugs.

Currently, there are technologies that can help to overcome these challenges and facilitate the delivery of larger amounts of drug through the SC route. This can be achieved either by enabling biologic molecules to be formulated or delivered as high-concentration injectables (>100 mg/mL for antibodies) or through facilitating the delivery of larger volumes of fluid (>3 mL).2

Glass Cartridges Protect Your Drug

Higher injection volumes and viscosities present a unique challenge to companies as they assess primary packaging component technologies. Primary packaging is of critical importance in biologics as this is the main point of contact between the drug and the device. Additionally, glass is easy to sterilize with heat and can protect medicines from ultraviolet rays. Finally, glass is easily recycled. These are all reasons why the global glass packaging market could reach $7.5 billion by 2028.3
