Tramadol/Togo. Der böse Geist aus dem Tablettenkoffer

In Westafrika berauschen sich viele Menschen illegal an Schmerzmitteln, die zum medizinischen Standard gehören. Eine strengere Kontrolle kann für Kranke schwere Konsequenzen haben. (faz.net, 10.07.2020)

Redesigning opioids may not prevent their fatal side effect

The dark side of opioids’ ability to deaden pain is the risk that they might kill their user. The same brain receptors that blunt pain when drugs such as morphine or oxycodone bind to them can also signal breathing to slow down. It’s this respiratory suppression that causes most overdose deaths.

So scientists have hoped to design opioids that are “biased” toward activating painkilling signals while leaving respiratory signaling alone. (Science, USA, 27.02.2020)

Europa. Europa wil beter zicht op gevaarlijke en zeer verslavende synthetische opioïden

Om Europa voor te bereiden op een toename in het aanbod en gebruik van zeer gevaarlijke synthetische opioïden (waaronder fentanyl en fentanyl-achtigen), gaat het Trimbos-instituut de situatie rond deze drugs in kaart brengen. (Trimbos-instituut, Niederlande, 19.02.2020)


Auf dem Weg zu Schmerzmitteln ohne Suchtgefahr: Säurewert am Schmerzherd ist entscheidend

Opioidhaltige Schmerzmittel sind im klinischen Alltag nahezu unverzichtbar, allerdings haben sie starke Nebenwirkungen. Zusätzlich ist es insbesondere in den USA zu massivem Substanzmissbrauch gekommen. Einem Forschungsteam der Charité – Universitätsmedizin Berlin ist jetzt ein wichtiger Schritt hin zu einer neuen Generation von Schmerzmitteln gelungen. Wie die Forschenden im Fachmagazin Scientific Reports* berichten, kommt es bei der Entwicklung neuer Substanzen auf den Säurewert, den pH-Wert, des Schmerzherds an. Denn die Feinabstimmung der Säure-Dissoziations-Konstante, der sogenannte pKa-Wert, eines Opioidmoleküls bestimmt die Gefährlichkeit, darunter das Suchtpotenzial. (Charité – Universitätsmedizin Berlin, 20.02.2020)

In Deutschland gibt es keine Opioidepidemie wie in den USA. Dennoch sind Experten alarmiert und bemüht, diese Analgetikagruppe nur streng indiziert zu verordnen und Risikofaktoren für einen Missbrauch zu definieren. Vor allem postoperativ lassen sich Opioide reduzieren.

Kanada. New research shows more people knowingly use fentanyl, points to importance of comprehensive response to reduce risks 

Fentanyl use by people who use drugs in B.C. has doubled since 2015, and two-thirds of people are aware they’ve taken it, finds new research from the BC Centre for Disease Control (BCCDC). (British Clombia Centre for Disease Control (BCCDC), 24.01.2020)


Fentanyl: The Most Dangerous Illegal Drug in America

Drug overdoses kill more Americans than car crashes, gunshots, or AIDS at its peak. But it's no longer just a crisis of prescription pills or heroin. It's a crisis of fentanyl. Deaths involving it and other synthetic opioids have surged from around 3,000 in 2013 to more than 30,000 in 2018. 

Researchers at RAND recently published the most comprehensive study to date on what's driving the crisis, how it could play out in the future, and what may be done to save more lives. Among their findings: 

Fentanyl is unlike any other drug problem in modern history. It's more useful to think of it as a mass poisoning than as a traditional drug epidemic.

The crisis is likely to get worse. Fentanyl and other synthetic opioids have swept through some parts of the country while leaving others almost untouched. There are signs that's changing.

Confronting the crisis is going to take more than disrupting the supply and getting people into treatment. Innovative, and controversial, responses—such as supervised drug-consumption sites and fentanyl test strips—must be part of the policy discussion. (RAND, USA, 13.01.2020)

Tramadol. 'Safer opioid' has sparked a crisis in vulnerable countries

Reports rolled in with escalating urgency—pills seized by the truckload, pills swallowed by schoolchildren, pills in the pockets of dead terrorists. 

These pills, the world has been told, are safer than the OxyContins, the Vicodins, the fentanyls that have wreaked so much devastation. But now they are the root of what the United Nations named "the other opioid crisis"—an epidemic featured in fewer headlines than the American one, as it rages through the planet's most vulnerable countries.
