Methadone is a full opioid agonist that binds to mu-opioid receptors, reducing withdrawal symptoms and cravings without producing a strong euphoric effect when taken as prescribed. In contrast, buprenorphine is a partial opioid agonist, meaning it also binds to mu-opioid receptors but with a ceiling effect, which lowers the risk of respiratory depression and overdose.
Pros and Cons
Methadone is highly effective for severe opioid use disorder and is taken once daily, but it must be dispensed at a licensed clinic, making access more restrictive. It carries a higher risk of overdose due to its full agonist activity and can cause sedation, respiratory depression, and QT prolongation. Withdrawal from methadone can be more difficult due to its long half-life.
Buprenorphine, on the other hand, is safer because of its ceiling effect and lower overdose risk. It can be prescribed in office settings, making it more accessible. However, it may not be strong enough for individuals with severe opioid dependence. It also has a lower risk of sedation but can cause precipitated withdrawal if taken too soon after opioid use…
