Adderall XR is a long acting version of Adderall which lasts up to 12 hours. It is a very effective medicine for the treatment of ADD/ADHD, and in fact is the most prescribed medicine in the US. Adderall XR has two beads in the capsule – an immediate release bead, and a delayed release bead – which ensures that the medicine lasts for a full 12 hours, while only taking the capsule only once per day.
As our awareness of adult ADHD grows, it is clear that many adults need longer acting coverage of their symptoms than just 12 hours. While many youth can finish their important tasks with 12 hours of medication coverage, many adults still have tasks that need getting done for up to 16 hours per day.
Shire, the makers of Adderall XR, were planning to create a 3 bead Adderall medicine. The idea would be to have an immediate release bead (for immediate symptom control), an intermediate long acting bead – which would release approximately 4-6 hours after ingestion (for mid day symptom control), and then a third long acting bead – which would help to provide up to 16 hours of symptom control.
It has been reported that Shire has decided not to pursue the development of this new medicine.
This relates to the fact that its new medication – Vyvanse – has demonstrated efficacy going beyond 13 hours. Perhaps further research will show that it actually goes longer than 13 hours.
I would guess that most of you would NOT feel a sense of loss, because I suspect that you didn’t know that the ‘triple bead’ adderall was a possibility.
