Buprenorphine is a partial agonist at the mu-opioid receptor, meaning it produces less intense euphoria but has longer lasting effects than full agonists because it does not fully occupy the receptor sites. Additionally, buprenorphine has higher affinity for these receptors compared to other opioids and so there is decreased risk for overdose due to respiratory depression (Scheerer et al., 2020). Buprenorphine also has antagonist properties at high doses that contribute to its effectiveness in treating opioid addiction (Gibson & Trafton, 2018)

Pros associated with methadone include its ability to reduce craving and withdrawal symptoms while maintaining relatively consistent levels within the body over time (Gibson & Trafton, 2018). Methadone is also known for its longevity since one dose can produce effects all day long – this helps maintain adherence since fewer doses must be taken each day by patients who may have difficulty remembering or adhering to their medication regimen (Scheerer et al., 2020). Another advantage of methadone is that it reaches peak concentrations quickly after ingestion so there’s less risk from dangerous peaks causing an overdose compared with immediate release formulations like heroin or hydrocodone (Gibson & Trafton, 2018). However, some drawbacks include potential for overuse leading to tolerance development as well as potential abuse liability due to its intoxicating effects when taken in high doses. Additionally, if individuals abruptly stop taking the drug they could experience severe withdrawal symptoms including sweating/fever/nausea/vomiting/diarrhea which can lead them back into substance use behaviors (Scheerer et al., 2020).

In contrast pros associated with buprenorphine include decreased risk from dangerous peaks causing an overdose because peak concentrations occur more slowly due its slow dissociation rate from mu-opioid receptors compared with methadone—meaning fewer overdoses –as well as reduced abuse liability due its lower potency when taken orally versus intravenously or nasally( Scheerer et al.,2020 ). Buprenorhpine’s antagonist properties also make it effective at blocking out other opioids’ reinforcing effect which further reduces potential for misuse or relapse during treatment( Gibson & Trafton ,2018 ). Lastly ,bupernorphine’s ease of administration makes it attractive too those struggling with chronic conditions who need steady dosing throughout the day( Scheerer et al.,2020) . Some cons related to bupreneophrine are that unlike full agonists ,it does not provide complete relief from cravings so abstinence might still be difficult even after taking this medication.( Gibson&Tafton2018 ) There is also debate around whether there could be unexpected side effects on organs such as liver damage caused by metabolites formed while breaking down this drug.( Gibsob & Tarftin2018 ) In addition ,some people may struggle more than others metabolizing this substance leading themto have higher levels build up quicker than anticipated thus increasing adverse reactions( Scheeereretal2020.)
