New Innovative Staked Needle Syringe

Schott has developed a new and highly innovative syringe system. The new product was presented under the brand Schott InJentle™ at the Schott Pharma Symposium in Mainz, Germany, in December 2009. SCHOTT InJentle™ was developed for the special needs of highly sensitive drugs. Its unique design offers improved drug stability and a gentle application.

“The drug is not in contact with the needle or the adhesive during storage”, said Carmen Heiter, Product Manager Syringes. “This prevents sensitive drugs from interacting with the adhesive or the metal of the needle.”

The innovative seal design allows the drug only to flow into the needle at the very moment when the syringe is opened. The tamperevident closure enables physicians or patients to determine if the syringe is still unused.

Schott InJentle™ exhibits a whole range of additional advantages. For example, the special geometry of the glass barrel does not require the use of any tungsten during the glass forming process. As a result, the syringe is completely tungsten-free.

“There is a growing segment of biotech drugs that are not only highlyeffective but also very sensitive,” explained Ralf Bouffleur, Vice President Schott Pharmaceutical Packaging. “The reliable protection of these drugs during storage is now calling for innovative packaging solutions like Schott InJentle™.”

Schott InJentle™ allows the use of particularly thin needles up to 32 gauge. “The thinner the needle,” according to Heiter, “the less painful the injection.” As Schott InJentle is very simple to handle, no special training is required for the healthcare personnel. “But although this syringe includes a number of special features, the syringe is delivered with standard nests and tubs”, says Heiter, “and can be filled on standard filling lines”.
A production line is currently being built to manufacture the InJentle syringe, with mass production planned to start at the end of 2010 in St. Gallen, Switzerland. Samples in 1ml long format are available for functionality testing.
