Schreiner MediPharm Enables Digital Adherence Monitoring with New Child-Resistant Smart Blister Wallet

Schreiner MediPharm offers a wide variety of smart blister packs for clinical trials. Now, thanks to the partnership with packaging specialist Keystone Folding Box Co., the expert for the pharmaceutical industry is extending its portfolio by a particularly child-resistant as well as senior-friendly solution. The use of integrated electronics turns blister packaging into a real time e-diary for capturing dosing history data.

Schreiner MediPharm has developed a smart extension for the proven Key-Pak® wallet for oral solid dose medication from U.S. based Keystone Folding Box Company. The novel solution combines a child-resistant paperboard package with state-of-the-art technology for digital adherence monitoring, and is suitable for customization.

Keystone is a leading company in the field of paperboard pharmaceutical packaging. Its Key-Pak® wallet card has become established as a packaging mainstay in clinical trials. To the Key-Pak®, Schreiner MediPharm adds electronic functions for medication adherence monitoring with numerous benefits.

The distinguishing characteristic of the “smart” Key-Pak® wallet is the integration of conductive trace-patterns linked to each of the cavity locations on the wallet card. As a result, data is generated at the moment the patient removes a dose from the wallet. The details, such as time and date of dose removal, and specific cavity location, are stored within the electronics inside the package, and can be transmitted by means of NFC or Bluetooth technology for precise patient compliance tracking.There is also an option to send medication dosing reminders to patients, and to adjust the therapy plan as needed. When used in combination with special software, central tracking as well as data documentation and analysis can be achieved.

The Smart Blister Wallet based on Key-Pak® is both child-resistant and senior-friendly. Ease of use by the patient, in terms of accessing each dose, is accomplished by a push-through safety feature which is a hallmark of the Key-Pak® design. Pharmaceutical companies are provided with a flexible solution that can be customized to any clinical trial and its dosing scheme, such as number of cavities, blister arrangement, and various tablet shapes. By enhancing data quality and optimizing processes, the Smart Blister Package can shorten trial duration, thereby accelerating the approval process for new drugs. In addition, Schreiner MediPharm ensures end-to-end automated production of the Smart Blister Package due to scalable state-of-the-art manufacturing processes. This innovative packaging solution increases efficiency and flexibility in clinical research settings, and emphasizes patient safety and comfort.
