THURSDAY, Jan. 11, 2018 (HealthDay Information) — Tamper-resistant opioid drugs — one try to curb prescription painkiller abuse — aren’t stopping overuse and overdosing, not less than in Australia, new analysis exhibits.

“This formulation was developed with the particular goal of decreasing tampering, focusing on behaviors reminiscent of injection or snorting,” stated the research’s lead creator, Briony Larance.

However there was additionally the hope that tamper-resistant formulations of oxycodone would possibly cut back opioid-related harms — reminiscent of overdose — extra broadly, she stated. Larance is a senior analysis fellow on the Nationwide Drug and Alcohol Analysis Centre on the College of New South Wales in Sydney.

“Till this research, it wasn’t clear whether or not or not they might do that,” Larance stated.

Tamper-resistant oxycodone did, nonetheless, cut back oxycodone use and injection by individuals who injected medicine, the research discovered.

Australia is within the midst of an opioid epidemic much like the one in the US. From 1992 to 2012, the speed of opioid use went up 15-fold in Australia, in response to the researchers. Seventy % of opioid overdose deaths in Australia are linked to prescription opioids, reminiscent of oxycodone (OxyContin) and morphine.

In the US, 2 million individuals have been depending on prescription opioids in 2015. And greater than 33,000 Individuals overdosed on opioids in 2015, with near half of these deaths attributed to prescription ache relievers, the U.S. Division of Well being and Human Providers studies.

A controlled-release model of oxycodone has been launched in the US. The drugs are exhausting and like plastic. If crushed, they break into giant items as an alternative of a high quality powder. And if water is added to the tablet, a thick gel-like substance types, making intravenous use or snorting up the nostril troublesome.

However as a result of different government-led efforts to cut back opioid misuse have been launched on the similar time, it is not potential to review the consequences of the controlled-release technique in the US.

A tamper-resistant type of oxycodone turned obtainable in Australia in 2014. The researchers collected knowledge from 17 knowledge sources there, together with opioid gross sales knowledge, well being datasets, surveys of people that inject medicine, and a gaggle of greater than 600 individuals who admitted to tampering with pharmaceutical opioids, Larance stated.


“We didn’t discover any impacts on population-level opioid use, overdose or assist or therapy looking for,” she stated.

“The overwhelming majority of individuals uncovered to pharmaceutical opioids in Australia are prescribed them and don’t inject medicine. This seems to restrict the effectiveness of tamper-resistant formulations as a method to handle population-level points reminiscent of overprescribing, overuse and hurt of opioids,” Larance defined.

“Tamper-resistant medicine are only one a part of a multifaceted technique we’d like in opposition to the opioid epidemic,” he stated. “And while you have a look at anyone intervention by itself, it might appear underwhelming. There will not be one miracle intervention.”

Additionally, it may be troublesome to check individuals utilizing medicine from one nation to a different. There are giant variations even from one area of the US to a different, he added.

So, if tamper-resistant medicine aren’t a solution to the opioid epidemic, what could be completed?

The creator of an editorial accompanying the report, Nabarun Dasgupta, stated there’s “an ideal want to search out extra artistic options.”

Dasgupta is a senior scientist on the College of North Carolina at Chapel Hill’s Faculty of International Public Well being.

“In the US, as we progress into the third decade of the opioid epidemic, we’re beginning to perceive a number of the root causes,” he stated. Issues like poverty and lack of job alternatives can gasoline “problematic drug use,” Dasgupta famous.

One such resolution, he stated, could also be present in Tennessee, a state with an opioid overdose epidemic. The state has made vocational colleges and neighborhood faculties free to its residents. This technique’s effectiveness stays to be seen. However Dasgupta stated it might be extra promising than different options tried prior to now.

The Australia research was revealed on-line Jan. 11 in The Lancet Psychiatry.
