Reply to comment by RabbitFuzz in The Vyvanse patent expires this year. How long does it usually take generic alternatives to get approved, and how much of a reduction in cost is expected on average? by paleselan1

Following that link, it appears that the Vyvanse patents expired on February 24^th . It will be interesting to see whether and how quickly these other manufacturers are able to bring a generic to the market.

The main patent expired Feb 24. But they are granted 6 months beyond that for exclusivity still for pediatric patients and supposed to use this time to study effects on kids. Basically most drug companies get a 6 month extension for pediatrics as they delay generics getting a chance and get extra time to rake in full price money and pretend to be studying effects on kids even if they’ve already had a decade to do so. So we have to wait til after Aug 24 2023.

That’s not how it works. The 6-month extension is granted if the company conducts a study in pediatrics at any point in time. I haven’t looked, but I assume Vyvanse is actually indicated for some pediatric patients already (most ADHD drugs are). The extension is simply an incentive young kids - a patient segment that is often under studied with new products.

Another company, which they sued around 2011, revamped production for the end date.
