SAN FRANCISCO (KRON) — A brand new research carried out by College of California San Francisco researchers discovered buprenorphine works for treating opioid use dysfunction, however a brand new micro-dosing approach was far much less efficient than hoped.
Through the COVID pandemic, when fentanyl overdose deaths surged in San Francisco and throughout the U.S., medical doctors had been determined to seek out methods of serving to their sufferers battling habit, a UCSF spokesperson stated.
Buprenorphine works by solely partly binding to the receptor that creates the fentanyl “high” with out the extent of euphoria of stronger opioids. Sufferers who’re nonetheless utilizing fentanyl and are handled with buprenorphine suffered from extreme withdrawal signs.

For the research, medical doctors began giving sufferers in San Francisco small doses over a sequence of days to slowly construct up the drug of their methods. This therapy approach can also be referred to as the microdosing method, or low-dose initiation. Of 126 members, simply 34% had been capable of work as much as a full dose of buprenorphine.
Leslie Suen, the research’s writer, stated she was upset by the outcomes, however the findings nonetheless must be shared publicly.
“This doesn’t seem like it’s working the way we had hoped,” stated Suen, an assistant professor at the united states Division of Basic Inside Drugs and an habit medication specialist. “When people expect it to work, and it doesn’t work for them, they feel like there’s something wrong with them.”
The research was revealed Friday in JAMA Community Open titled “Outpatient Low-Dose Initiation of Buprenorphine for People Using Fentanyl.”
The research’s members had been handled at two outpatient substance use dysfunction clinics in San Francisco between Might 2021 and November 2022. They opted both for seven days of taking low doses of buprenorphine earlier than getting as much as an optimum dose (dosing two or thrice a day), or 4 days of therapy (dosing 4 instances a day).
Docs had hoped that slowly introducing the buprenorphine would assist cut back the discomfort of detox, and folks might cease utilizing fentanyl once they felt prepared.
At follow-up visits, 38% of these with the four-day routine achieved profitable buprenorphine initiation and 28% had been profitable on the seven-day protocol, for an total success charge of 34%. Twenty-two p.c stayed on the drug for not less than 28 days.
