ketobemidone is a prescription opioid in a few countries, it is also reportedly more euphoric than any other opiate does anybody have any information about this drug?
 
25mg of keto is equal to roughly 60mg of morphine. in studies back in the 50s it was indicated that its more addictive than other opiates. the pain relieving effects can be felt at a much lower dose than the euphoric effects, while with morphine for example, euphoria and pain relief are achieved at the same dose level
 
Ketobemidone is C1 in the US.

It's prescribed in Sweden i believe.. but you have to be practically dying to get it.
 
so its like the fentanyl of Sweden...

It's not as nearly potent as fentanyl I.V. This stuff can be rather dangerous in high enough doses, as higher doses may have a NMDA antagonistic tranquilizer like effect with the opiate effect if the painkilling is at a lower dose than the euphoria. This drug may put you in a opiated dissociative "Hole."

I must do a little more reseach... It seems as though the NMDA effects are what is doing most of the painkilling at the standard doses.
 
I have heard of several people on other forums, and on one erowid trip report describing it as being used because it is able to "break through" methadone treatment and still deliver a high probably because of NMDA antagonism. I have also heard that several reports referring to it as the most euphoric opiate because of its intense rush upon administration. However, the current pharmacutical preparations prescribed in sweden use a salt which dramatically reduces bioavailability increasing the required dose, and reducing euphoria. The few people who reported using it prior to the change in preparation that I was able to find described it as the having a greater rush than any other opiate.
Psychedelic Jay- I do not think you are at risk of a dissociative "hole" because its painkilling properties come from the addative combination of NMDA and opiate agonism. This is why it takes less than a euphoric dose to provide pain relief while the NMDA antagonism is comparatively weak against mu opiod action. I also think that this means that it may not be as much of an overdose risk as may be expected because NMDA antagonism is virtually impossible to OD on, and so at euphoric doses you would feel a stronger high, but less risk of overdose because less of the effect comes from opiate receptors, and thus you are less likely to OD.
