Treating Opioid Addiction with Science-Based Methods: The Reality
“The goal always is reducing or eliminating the use of illicit opioids and other illicit drugs and the problematic use of prescription drugs.”
This statement from Treatment Improvement Protocol (TIP) 43, published by the Substance Abuse and Mental Health Services Administration, challenges the myth of “substitution.” The goal of MAT is harm reduction and the stabilization of patients who would otherwise be unable function without opioids. With supervised MAT programs, these people can be functional members of society, capable of making healthy decisions for their well-being.
The National Institute on Drug Abuse, the Centers for Disease Control and Prevention and the World Health Organization all recognize medication-assisted treatment as the “gold standard” of opioid addiction treatment, and in September 2018, Surgeon General Jerome M. Adams issued a report calling for access to FDA-approved medications — along with behavioral interventions and support groups — as a component of treatment.
The
surgeon general’s report acknowledged an undeniable truth.
“Unfortunately, stigma has prevented many sufferers and their families from speaking about their struggles and from seeking help. The way we as a society view and address opioid use disorder must change — individual lives and the health of our nation depend on it,” he wrote in the preface.
In order to dispel the belief that MAT is just the substitution of one addiction for another, experts have explained how these drugs work.
Methadone, buprenorphine and naltrexone can all be used to treat opioid addiction, but they work in different ways.
Opioid Agonists: Methadone and Buprenorphine
The FDA has approved two opioid agonist drugs for opioid use disorder and mandates that both —as well as a third option, naltrexone — be made available to patients. The FDA has also advised that treatment with any of these medications continue as long as necessary for a patient’s full recovery.
Methadone
Opioid agonists, including methadone, activate opioid receptors in the brain. This means is methadone works like heroin and prescription opioids, but its
long-acting properties reduce cravings and ease withdrawal symptoms without producing euphoria.
This withdrawal-free, euphoria-free state allows patients to function normally by tricking the opioid-dependent brain into believing that it has received its expected dose of heroin or prescription opioids.
Buprenorphine
Classified as a partial opioid agonist, buprenorphine has both agonistic (activating) and antagonistic (blocking) effects. Like methadone, buprenorphine activates opioid receptors but to a lesser degree when it attaches to a person’s opioid receptors. At the same time, it blocks other opioids, such as heroin or morphine, from attaching to the receptor. This limits their euphoria-producing abilities.
Thus, the freedom from withdrawal symptoms and the absence of a high diminish the compulsive drug-seeking behaviors characteristic of addiction.
Additionally, buprenorphine has a ceiling effect, which makes it less likely to cause respiratory depression and other side effects associated with opioid agonists.
Methadone and buprenorphine have the potential for abuse, but when used under medical supervision, the drugs are generally safe and effective in treating opioid addiction. Additionally, SAMHSA mandates that all medication-assisted treatment programs include behavioral therapies and support programs, as well as regular drug testing.
Dr. Kevin Wandler of The Recovery Village talks about the effectiveness of methadone and how the medication helps people overcome opioid addiction.
Opioid Antagonists: Naloxone and Naltrexone
Naloxone and Naltrexone are opioid antagonists, which means they do not activate opioid receptors. They bind to the receptors and block the effects of opioids.
Naloxone
Naloxone can immediately reverse the effects of an opioid overdose.
Doctors sometimes prescribe naloxone with buprenorphine if a patient is at risk of misusing buprenorphine. Suboxone, Zubsolv and Bunavail all contain a combination of buprenorphine and naloxone.
Because the risk of overdose is greater after a period of treatment, when a person’s tolerance is lower, Narcan, a nasal spray formula of naloxone, is an essential component to medication-assisted treatment.
But naloxone has also faced opposition from policymakers and law enforcement who see the drug as an expensive and undeserved indulgence for irresponsible addicts. In Ohio, Sheriff Richard Jones told the Huffington Post that Narcan, the brand name for naloxone, enables people.
“This Narcan, all it does is save people’s lives for another day.”
And in Maine, Gov. Paul LePage, whose controversial comments about traffickers named “D-Money, Smoothie, [and] Shifty” made headlines in 2016, vetoed a bill to increase access to naloxone.
“Creating a situation where an addict has a heroin needle in one hand and a shot of naloxone in the other produces a sense of normalcy and security around heroin use that serves only to perpetuate the cycle of addiction,” LaPage wrote in his veto letter.
Naltrexone
Naltrexone, which is also used to treat an alcohol use disorder, may be used to treat opioid dependence. It is nonaddictive and blocks the euphoric effects of opioids and alcohol. Naltrexone, known by the brand name Vivitrol, is not as tightly regulated as buprenorphine and methadone, and any licensed prescriber can write a script for the medication without limitation.
