Methods: Data on pharmaceutical opioid sales; drug use by people who inject drugs regularly (PWID); client visits to the Sydney Medically Supervised Injecting Centre (MSIC); and last drug injected by clients of inner-Sydney needle-syringe programmes (NSPs) were obtained, 2009-2014. A cohort of n=606 people tampering with pharmaceutical opioids was formed pre-April 2014, and followed up May-August 2014.
Results: There were declines in pharmacy sales of 80mg OxyContin® post-introduction of the reformulated product, the dose most commonly diverted and injected by PWID. Reformulated OxyContin® was among the least commonly used and injected drugs among PWID. This was supported by Sydney NSP data. There was a dramatic reduction in MSIC visits for injection of OxyContin® post-introduction of the new formulation (from 62% of monthly visits pre-introduction to 5% of visits, August 2014). The NOMAD cohort confirmed a reduction in OxyContin® use/injection post-introduction. Reformulated OxyContin® was cheaper and less attractive for tampering than Original OxyContin®.
Conclusions: These data suggest that, in the short term, introduction of an abuse-deterrent formulation of OxyContin® in Australia was associated with a reduction in injection of OxyContin®, with no clear switch to other drugs. Reformulated OxyContin®, in this short follow-up, does not appear to be considered as attractive for tampering.
