Even though the next patent for OxyContin (oxycodone ER) isn't set to expire until June 2017, we may see a generic version introduced as early as October 2014. However, this date could be changed, due to lawsuits or other reasons, so it's hard to predict when the drug will actually be available in generic form.
Generic for OxyContin: An Overview
OxyContin® (oxycodone ER) is a prescription pain medication. Although generic OxyContin was available and sold by various different manufacturers in the past, several legal battles have resulted in these generics being removed from the market. Brand-name OxyContin is made by Purdue Pharma L.P.
Generic OxyContin Availability
As the result of several lawsuits and settlements, many of the manufacturers that previously made generic OxyContin products were forced to stop making such products. Only a few manufacturers were allowed to continue to make their generic versions. These manufacturers include IMPAX Laboratories and Mallinckrodt, Inc.
The agreements between these manufacturers and Purdue Pharma L.P. (the manufacturer of OxyContin) were temporary; the agreement with IMPAX has expired and the agreement with Mallinckrodt also appears to have expired. Thus, generic OxyContin is no longer available.
When Will Generic OxyContin Become Available Again?
The first patent for OxyContin expired in April 2013. However, this patent applied to the original OxyContin version, which was easier to abuse than the current version. The next patent is set to expire in June 2017. However, a settlement agreement between the manufacturer of OxyContin and Actavis (a generic manufacturer) allowed a generic version to enter the market as early as January 2014.
Since no generic versions became available in January 2014, the next predictable date to expect the possibility of generic OxyContin is October 2014, when Actavis will be allowed to sell an "authorized generic" version (brand-name OxyContin repackaged as a generic).
This is the earliest predictable date that generic OxyContin will become available again. However, other circumstances could change this date. This could include such things as lawsuits or other patents for specific OxyContin uses.
