Rx Update March 2008 OxyContin Update New Strengths to Market OxyContin® (oxycodone extended-release) is a controlled-release opioid analgesic indicated for the management of moderate to severe pain when continuous analgesia is needed for an extended period of time. Marketed by Purdue Pharma L.P., OxyContin was previously offered in only 10mg, 20mg, 40mg and 80mg formulations. In January 2008, additional strengths of brand-name OxyContin became available. These new strengths include 15mg, 30mg and 60mg formulations. The dosages of OxyContin 60mg and 80mg are only indicated for opioid-tolerant patients and should not be used for initial opioid-naïve patients. Generic Supplies Dwindling On December 31, 2006, production of the generic formulation of oxycodone sustained-release was halted due to patent infringement settlements between generic pharmaceutical companies and Purdue Pharma L.P. Generic oxycodone sustained-release formulations were not required to be withdrawn from the market and the supply has remained available, despite production termination from the generic manufacturers. More recently, sporadic supply issues with the generic product have started to appear. In response to dwindling supplies, brand-name OxyContin has switched classification status in the national drug database system from a “brand-with-a-generic-alternative” drug to a “single-source-brand” drug as of early February 2008. This means that members will not incur a copayment penalty when requesting brand-name OxyContin for prescription plans with a mandatory generic plan, and brand claims will adjudicate according to the formulary status of OxyContin (preferred brand copayment for clients on the Catalyst Rx formularies). Pharmacies may also continue to dispense generic oxycodone sustainedrelease until supplies are exhausted. The patient will continue to incur a generic copayment for the generic product. It is anticipated that all supplies of the generic oxycodone sustained-release will soon be exhausted and only the brand formulation of OxyContin will be available. As a result, the client cost for this product will increase. Currently, the average ingredient cost for a one-month supply of a generic oxycodone sustained-release prescription is $225. The current average branded OxyContin ingredient cost for a one-month supply is $527.
