Technology

StratoSphereHL™ is a coated microsphere, with an inner core consisting of the drug molecule and a minor amount of a matrix forming excipient, and another excipient forming an outer coating which does not contain any drug.

Neither the excipients, nor the microsphere concept as such, are new to the world of drug delivery. However, we've decided to let each excipient do what it's best at, and to strictly keep them apart. The inner one carries the drug, offering a mild and favourable environment both during manufacturing, storage and use, as well as an exceptionally high payload capacity. The outer one controls the release rate, through a predictable degradation process trigged and maintained by the interstitial aqueous environment in the s.c. or i.m. tissue into which the injection is made.

Sounds simple? We think so, with a combined 40+ years
in drug delivery and microspheres.
