Teva oxycodone m/r: old thread

[gauchoamigo]

I have just been reading an old thread about TEVA-US stopping the manufacture of m/r oxycodone tablets. Since oxycodone was only introduced in 1996, how is it possible that US Patent Laws allow such a short period before generics become available? Here where I live, there can not be any generic oxycodone marketed until at least 2016. It's all original name brand stuff. I once tried the US Tevas and I'm afraid that they were so bad that I had to double my normal dosage just to get a little relief from my pain. And that was chewing the danmed things up, too! They seemed soft and chewy, not harder and brittle like originals.
The US must have really short lives on patents for medicines. And one more thing; is it true that you can actually get 30mg i/r oxycodone in the US? The highest instants (OxyNorm) available here are 20mg, and they would only be prescribed under exceptional circumstances, otherwise the highest dose tablet a doc would write you up for would be 5 or 10mg i/r.

It all had to do with an extended

patent due to a lawsuit by Purdue

Ask Roxy stardust she know's

All the particular's

I thought oxycodone came WAY before 1996.

"I believe from reading the Purdue lawsuit that their patent on OxyContin is good until 2013; OxyContin was FDA approved in 1996."--from one of Roxi's sticky threads in this forum. I don't know why Teva and Watson started making generics so far before the patent would expire, but Purdue has put a stop to that.

And yeah, Roxicodone is the brand name of the IR 15 mg and 30 mg oxycodone. There are generics too.

OxyContin was 1996, I'm pretty sure Percocet and Percodan came way before. (Wikipedia says 1950 for Percodan!)

The amount of time a patent is good for depends on a few different things but the main one is the amount of time the maker of the product asks for when applying for a patent and the amount of time they are actually given by the courts. Purdue was able to get a long patnet because they patented the drug; time release oxycodone AND the time release Matrix.
