There
are three MAT drugs available to treat addiction: naltrexone (brand
name Vivitrol), methadone (brand names Dolophine or Methadose)
& buprenorphine (brand name Suboxone, Subutex, and
Sublicade).
The
only MAT drug appropriate for initiation in the ED is
buprenorphine.
Buprenorphine is a semi-synthetic opioid which
acts as partial agonist at the mu receptor. Buprenorphine does not
produce as much euphoria or as much of the respiratory depression
seen with other opioids. It has a quick onset and long half-life
and is usually administered sublingually. The most commonly used
formulation of buprenorphine is mixed with naloxone for one reason
and one reason only - to prevent diversion and IV drug use. When
taken orally, the buprenorphine effect is predominant; when taken
IV, the naloxone effect is predominant
Any
ED provider can administer buprenorphine in the ED for up to 3
consecutive days in order to bridge a patient to addiction
services.
X-Waivers allow you to prescribe buprenorphine
from the ED, which is a great service you can provide your
patients, particularly in rural communities. In 2019 ACEP will be
producing an ED physician specific X-Waiver training which will
focus exclusively on ED-based care.
