Dromoran-Roche 2 mg ampoules ( Levorphanol) from the 1950s
I present this package of Dromoran ampoules ( from the Roche company) Each one consits of 2 mg of Levorphanol which is around 7,5 times stronger than morphine as has a longer duration of effects - so 2 mg are equal to 15 mg morphine.
The Box is from the late 1950s and comes a along with a leaflet and a scratch to open the bottles. Has anyone experiences with it ? If so, then I would be interested to hear on how it feels.
