Eukodal was apparently a trade name for oxycodone. I guess someone misread a handwritten u as an n when transcribing Morells records?<p>Googling &quot;enkodal&quot; finds a bunch of OCR misses from Google Books, where &quot;eukodal&quot; is mistranscribed with an n, and also an article[0] about how Hermann Göring was admitted to a hospital in 1924 to treat his opioid addiction. The article states that he was addicted to Eukodal, and among other things quotes a medical journal where it is mispelled as &quot;Enkodal&quot;.<p>[0] <a href="http:&#x2F;&#x2F;langbrosjukhus.se&#x2F;hermann-goring&#x2F;" rel="nofollow">http:&#x2F;&#x2F;langbrosjukhus.se&#x2F;hermann-goring&#x2F;</a>
