LG Chem Launches Cartridge-Replaceable Self-Injection Growth Hormone 'Utropin EcoPen'

Spring-Driven Injection for Easy Use with Less Force

Highest Capacity Among Domestic Cartridge-Type Injectors

LG Chem is introducing a new Utropin product equipped with an upgraded pen injector, aiming to expand treatment options for children receiving growth therapy and their caregivers.

On April 21, LG Chem announced the official launch of its first injection solution cartridge replacement set under the Utropin growth hormone brand: "Utropin EcoPen 48" (injection device, hereafter "EcoPen") and the EcoPen-dedicated injection solution "Utropin Cartridge 48IU."

Unlike existing all-in-one cartridge products, the EcoPen is designed so that users can attach and replace a dedicated cartridge, the "Utropin Cartridge 48IU," to the injector, allowing for multiple uses of the pen device.

LG Chem analyzed that the device plays a crucial role in reducing both psychological and physical burdens during long-term, repeated injections. In partnership with Ypsomed, a global drug delivery device company based in Switzerland, LG Chem focused on upgrading the pen injector from the user’s perspective. To provide a more comfortable injection experience, the device features a spring-driven semi-automatic injection method instead of relying on hand pressure, and it accommodates a 48IU cartridge—the largest capacity among domestic growth hormone products.

This allows children with small hands to easily self-inject using the force of the spring instead of pressing force. The injection button length is fixed at 3 mm regardless of the dosage, ensuring consistently low injection pressure.

Additionally, considering the durability required for a reusable injector, the body is made of metal rather than plastic. The device also features a "remaining dose customization" function, which prevents users from setting a dose greater than the remaining amount during the final injection. Features such as a winding sound during injection and real-time dose tracking have been added, enabling users to intuitively monitor the injection process.

Alongside these upgrades, LG Chem launched the EcoPen with the highest capacity—48IU—among domestically available growth hormone products. This extends the cartridge replacement cycle, making daily growth therapy more convenient for users.

Sung Ho Kim, Head of Specialty Care Business Division at LG Chem, stated, "As the top brand in growth hormones, we have been conducting a large-scale Utropin observational study on Korean pediatric patients since 2012. By systematically building real-world treatment data, we will propose optimal therapeutic solutions and at the same time provide an easier and more comfortable injection environment, serving as a strong support for the growth therapy of children with short stature."
