Liquid stick packs : Overview
We pioneered liquid stick-pack technology, and it is widely accepted and preferred over legacy delivery forms by patients in Europe. We foresee this trend coming to North America. Portable, affordable, and safe, it is an excellent alternative to glass ampules, vials and traditional rectangular sachets. Through the Colomiers and Rochester sites, Unither can manage the full development of a drug product or a medical device from conception to the marketing stage, providing the benefit of Unither's development expertise.
Advantages of liquid stick packs
One of the biggest advantages of liquid stick packs technology is its ability to deliver portable, pre-measured doses, thus helping patients take the right dose at the right time.
Unit-doses are easy to carry, robust, simple to use, and protect the product until its expiry date. They are perfect for the modern, active lifestyle.
Liquid stick packs are ideal for syrups, solutions, and suspensions for oral administration and liquid or semi-solid topical formulations. They are thus excellent for cough (dry or productive) and cold treatments, gastroenterology (antacid preparations), pain relief, food supplements and dermatology.
We are able to provide boxes of stick-packs at a similar price to the equivalent quantity in bottles. Our R&D teams are developing new preservative-free formulations that will create new markets for liquid oral and topical products.
We are currently running cGMP stick-pack batches in both France and the US. Both sites are inspected by European Authorities to provide the products to the European markets. The US Site is FDA inspected to supply the American market.
With investment in new liquid stick-packs lines, the increasing capacity developed at Unither enables the sites to welcome new products in development alongside existing products.
We perform tech-transfer of products developed by our customers or third parties, and our highly trained, dedicated R&D teams can fully develop custom drug products and medical devices from the earliest stages.
