Oxycodone is also better tolerated than tramadol in post-operative pain surgery (Wirz et al. 2005; Riley et al. 2008). Thus, the better analgesic efficacy of oxycodone combined with less deleterious physical side-effects appears to explain why oxycodone became the top choice in moderate-to-severe clinical pain management. Policies and interventions that could keep people in remission (i.e., reduce the return to OUD rate) include removing obstacles to full reintegration into society, such as employment supports (29). Other policies would support people to maintain improvements in social role functioning, which is a predictor of sustained abstinence (30).
- This broad range allowed us to identify potential leverage points for intervention that others have not explored, including fentanyl harm reduction, recovery support, and increases in buprenorphine capacity (as opposed to testing the effects of treatment receipt).
- Similarly, we find strong evidence that synthetic opioid death rates rose disproportionately in areas more exposed to reformulation.
- Nonetheless, buprenorphine’s availability varies widely by state, and people of color are persistently underprescribed this lifesaving medication.
- In Figure 2D, we study the aggregated measure of opioid overdoses (T40.0–T40.4, T40.6), thereby incorporating opioid overdoses not specified as a particular type of opioid.
- Oral oxycodone has better bioavailability (about 60–90%) than morphine and with the same unbound concentrations of oxycodone and morphine in the blood, unbound oxycodone in the brain is as much as six times higher than morphine (Boström et al. 2008).
State Health Facts
- We begin by studying heroin overdoses over a longer time period than previous work, permitting us to test whether their relationship with OxyContin reformulation weakened over time, as we would predict if reformulation led to decreases in initiation.
- As the overdose crisis evolves, communities of color in particular have experienced a surge in fatal overdoses – deaths that are often preventable.
- In the years that followed, attacks on the 12-hour claim largely dropped from the agenda of Purdue’s critics.
- By 2010, one out of every five doctor’s visits in the U.S. for pain resulted in a prescription for narcotic painkillers, according to a Johns Hopkins University study.
As posits the canonical model, opioids induce reward by disinhibiting VTA and NAc dopaminergic neurons through inhibition of GABAergic inputs (Johnson and North 1992; Labouèbe et al. 2007; Barrot et al. 2012; Bourdy and Barrot 2012; Margolis et al. 2012). Therefore, oxycodone may cause robust and stable DA release by decreasing the excitability of GABAergic MSNs (see label 1 on the figure), thus blocking their potential tonic inhibitory action on the DA terminals in the NAc. Oxycodone may also inhibit other NAc interneurons that innervate directly the dopaminergic terminals (label 1) and the GABAergic inputs on these dopaminergic neurons in the VTA (label 1). As our unpublished data suggest, the robust and stable increase in global and phasic releases of DA in the presence of oxycodone might involve the selective stimulation of putative opioid receptor heterodimers or potentially different signaling cascades compared to morphine.

Longitudinal natural history studies that follow a nationally representative group of people with OUD in and out of treatment and remission lasting at least 1 year would be especially useful for improving transition rate estimates once people have developed OUD. Package 2 (Fig. 3B and fig. S4) included the same strategies as package 1, except that we removed the fentanyl harm reduction strategy (#10 in Table 1). Removing the fentanyl harm reduction strategy means that package 2 achieves much smaller annual and cumulative reductions in opioid overdose deaths by 2032 (a maximum of 19.1% annually in 2032 and 11.8% cumulatively) than package 1. These reductions are only slightly larger than the reductions from the fentanyl harm reduction strategy alone (14.2% peak annual reduction in 2025 and a cumulative reduction of 11.3%). The OUD annual reduction as of 2032 is slightly larger relative to baseline (16.3% compared to 15.1%) due to more people with OUD dying absent the fentanyl harm reduction strategy. The fentanyl harm reduction strategy and the two recovery support strategies appear to surpass the effects of naloxone kit distribution by 2032.
Oxycodone in the Opioid Epidemic: High ‘Liking’, ‘Wanting’, and Abuse Liability
Overdose Data to Action (OD2A) is a cooperative agreement that provides funding to 90 health departments under two distinct OD2A programs (State and Local) to reduce drug overdoses and the impact of related harms. This cooperative agreement supports jurisdictions in implementing prevention activities and in collecting accurate, comprehensive, and timely data on nonfatal and fatal overdoses and in using those data to enhance programmatic and surveillance efforts. OD2A focuses on understanding and tracking the complex and changing nature of the drug overdose crisis by seamlessly integrating data and prevention strategies. In Figure 3A, we observe a pattern for cocaine overdoses similar to the one estimated for synthetic opioids (Figure 2B). The results suggest a strong relationship between prior OxyContin misuse and the rise in cocaine overdoses after reformulation, but the effect is delayed. The 2017 estimate is 5.5, implying that a one standard deviation increase in exposure to reformulation increased cocaine overdoses by 1.3 per 100,000.
People most likely to witness an opioid overdose
Table 3 includes the equivalent result from the parametric model, suggesting even larger effects. We estimate a similar, though delayed, pattern for synthetic opioids in Figure 2B. Again, the estimates are flat prior to reformulation, suggesting the absence of confounding trends. We observe a rise in the estimates for synthetic opioid overdoses beginning in 2013, and these effects then escalate precipitously until the end of the sample.
Are people seeking treatment for opioid addiction?
We plot the population-weighted averages by year of the counterfactual overdose rate. We could also plot the counterfactual rates prior to 2010 using the event study estimates—they are close to the observed rates (as should be clear from Figure 4). Each admission record reports up to three substances of abuse at the time of treatment. We consider any admission in which heroin is listed as either the first, second, or third substance as a heroin substance abuse treatment admission. As a complementary measure to help capture escalation to dependence, we study substance abuse treatment admissions in the Treatment Episode Data Set (TEDS) for 1999–2017. The TEDS, which is maintained by the Substance Abuse and Mental Health Services Administration (SAMHSA), includes admissions data from all treatment facilities receiving public funding, whether through federal block grants, Medicaid or Medicare insurance, or other state funding https://ecosoberhouse.com/ sources.
Suspect arrested 1 year after Garden City teen fatally overdoses
From the standpoint of efficiency for shipping and trafficking, fentanyl is easier to transport and sell than how addictive is oxycontin heroin. Fentanyl’s entry into the illicit drug market, in particular in combination with heroin, led to a doubling and tripling of overdose deaths around 2012 to 2013. In Figure 2C, we explore the effect of exposure to OxyContin reformulation on natural and semisynthetic opioids, the category that includes OxyContin.
