Schreiner launches First-Opening Indication for Prefilled Syringes

Schreiner MediPharm has launched a new tamper-evident security concept for luer-lock syringes: Cap-Lock features a combination of a cap adapter and label that firmly seals prefilled syringes and reliably indicates any first opening.

Schreiner reported it in a press release on Tuesday, saying that this ensures the integrity of the primary container and prevents any undetected opening of the cap.

Further describing Cap-Lock, Schreiner said it is a specially constructed plastic cap adapter that is precisely placed on top of the primary closure of the syringe to equalize the diameter differences of the syringe body and closure. Subsequently, a label with an integrated perforation for tamper evidence is applied that wraps around the syringe body and the bottom part of the cap adapter.

“When a user opens the syringe cap the label is partially destroyed, thus clearly and irreversibly indicating that the cap has been opened. This enables the user to quickly and intuitively tell if the medicine has been tampered with. Thus, patients are protected against administration of potentially counterfeit substances,” Schreiner’s description reads.

The utilization of Cap-Lock in daily healthcare settings is particularly easy, intuitive and safe: The syringe can be opened as usual and, due to the larger diameter, the adapter is easier to twist off even with gloves, the company further explained.

Schreiner MediPharm will present the newly developed Cap-Lock to an expert audience for the first time at “PDA Universe of Pre-filled Syringes and Injection Devices 2019” in Gothenburg/Sweden in October.
