Episode 396: Buprenorphine, Fentanyl and the Opioid Crisis: What Medication for Opioid Use Disorder Really Does with Nick Casale, PharmD

Maybe someone you love is starting treatment for opioid use disorder and their doctor mentioned buprenorphine, or a monthly shot, and you're thinking, Wait... isn't that swapping one opioid for another? Or maybe you're the one struggling, and the idea of withdrawal feels so terrifying that treatment doesn't feel possible. Those fears make so much sense. And a lot of what we've been told about these medications is confusing, outdated or wrapped up in stigma.In this episode I sit down with Nick Casale, a pharmacist who has spent the last 15 years in addiction medicine, focused on opioid use disorder. Nick started out in a Pennsylvania Medicaid health plan in the early 2010s, right as the opioid crisis was exploding, and watched firsthand how inconsistent, and sometimes punishing, treatment coverage was. Today he works in medical affairs for a pharmaceutical company, talking with clinicians, researchers, and even sheriffs and jail medical directors about what the evidence shows.Nick breaks down how buprenorphine works in the brain (there's a great musical-chairs metaphor in here), why fentanyl has made opioid use disorder so much harder to treat, and what long-acting injections are changing, especially for people leaving jail. And we talk about the part medication can't do alone: counseling, support, peers who've been there. It's a hard topic. The numbers are heavy. But there's real hope here. Treatment works, access is better than it's ever been, and reaching out is a brave first step.In This EpisodeNick's path from retail pharmacy to a Medicaid health plan to addiction medicine, and why he fell in love with this workWhy insurance coverage for opioid use disorder treatment was "all over the board," and how kicking people off treatment for a failed drug screen made things worseWhat buprenorphine is, in plain language: a partial opioid agonist that holds the receptor, eases withdrawal and cravings, and blocks other opioidsThe three waves of the opioid crisis: prescription opioids, then heroin, then fentanyl and other synthetic opioidsHow fentanyl changes the brain by creating more opioid receptors, and why that makes withdrawal so brutalTablets and films vs. long-acting weekly and monthly injections, and why steady levels matter nowMedication for opioid use disorder in jails and prisons, and why the days after release are so dangerousHow buprenorphine can be misused, and why naloxone was added to some formsWhat real-world research is showing beyond clinical tr
