When it comes to administering insulin, many people prefer an insulin pen over the standard syringe and vial because they find pens more convenient and more accurate. And pre-filled disposable pens are easiest of all, because you don’t have to install a new cartridge when the pen is empty–you just toss it out.
Soon there’ll be a new player in the disposable pre-filled pen market: Sanofi-aventis’s SoloStar disposable pen comes pre-filled with Lantus, the long-acting insulin that’s injected once daily. The pen, which can administer doses from one to eighty units per injection, needs to be refrigerated until first use; after that, it’s fine at room temperature for up to 28 days.
A recent study indicated that the SoloStar’s injection force is about thirty percent less than other popular disposable pens. Another study (sponsored by sanofi-aventis) pitted SoloStar against two other established pens. Most of the 510 patients in the study preferred the SoloStar with regard to design and esthetics. In addition, more of them were able to correctly prepare the pen and perform an injection when using SoloStar.
Sanofi-aventis expects the SoloStar pen to hit pharmacies sometime this year.
