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 January 2014. This is due to a settlement between two companies. However, lawsuits or other patents for new uses of the drug could change this date.
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.
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.
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 for OxyContin is set to expire in June 2017. However, a settlement agreement between the manufacturer of OxyContin and Actavis (a generic manufacturer) will allow a generic version to enter the market as early as January 2014.
This is the earliest predictable date that generic OxyContin will become available again. However, there are other circumstances that could change this date. This could include such things as lawsuits or other patents for specific OxyContin uses.
