Looking at an old drug repurposed to treat opioid addiction, a new study found long-acting formulation of morphine (SROM) promising for curbing the opioid epidemic.
Many people who overdose on fentanyl have untreated opioid addiction. Left untreated, opioid addiction can have devastating consequences. One of the reasons for the low treatment rates is that current medications have limited ability to retain people in treatment. The Canadian National Guideline for the Clinical Management of Opioid Use Disorder recommends treatment with slow-release oral morphine, also known as SROM—prescribed as a third line of therapy. In this study, we wanted to compare Kadian® and Methadone for the treatment of opioid use disorder.
|QUICK FACT: Slow release oral morphine (SROM) is given once daily and has been proposed for people who do not tolerate or respond to methadone.|
We looked at the scientific literature up until the May of 2018. Then, we wanted to see if SROM (brand name Kadian®) works as well as methadone in the treatment of opioid use disorder. In the study, we included people of any gender, age or ethnicity.
We found four unique clinical trials that met inclusion criteria (n = 471), and compared Kadian® with methadone. Meta-analysis of existing clinical trials suggests SROM (slow release oral morphine) may be as effective in retaining patients in treatment and reducing heroin use.
This is the first meta-analysis of slow release oral morphine (Kadian®). We included new studies that increase the validity of the study. We included previously unpublished data obtained from primary trials. A pooling of data for craving and adverse events was not possible due to inconsistent reporting of outcome measures across trials
SROM seems as good as methadone for the treatment of opioid use disorder but retains people in treatment longer.
While methadone is effective for many patients, these findings suggest SROM may provide benefits in addressing some of the limitations of methadone. We need to expand uptake and retention of people on opioid use disorder treatments. These data should compel public health agencies and decision makers to find therapeutic tools for people who have opioid addiction.
We are running out of options for helping people overcome opioid addiction and abandon contaminated fentanyl. But revisiting this medication, known from cancer treatment, can have a dramatic impact on addiction treatment success because it is not only equally effective as the current treatment options but also better tolerated by patients. Expanding treatment options responds to patients’ needs by offering drugs with fewer side effects.
Kadian® slow-release oral morphine is available in 10mg, 20mg, 50mg, and 100mg capsules, which may be combined as necessary.

Against the use of opioids for chronic non-cancer pain to people who have active substance use disorders advises the third recommendation in the new opioid therapy guidelines (May 8th, 2017).
However, this “strong” recommendation is based on low quality of evidence from studies that rarely involve people with active substance use disorders (SUD). (more…)
What is the future of addiction medicine? What is the future addiction specialist going to look like? Nobody knows what the future is going to look like, but the delegates of the 25th CSAM annual conference imagined answers to these questions in Banff, Alberta at the Banff Centre on Tunnel Mountain. As a first comer to the conference, I had a lot to learn and a lot to write down. Read more below.
