A semisynthetic opioid analgesic developed in 1917, prescribed primarily for pain management. It has become extremely popular as a recreational drug in some areas, and carries a high potential for addiction. Reported as being a little more 'stimulating' than other opioids.
⚠️ Dosages reflect that, while nasal bioavailability (BA) may be less than oral BA, nasal administration causes an additional 'rush' (due to quicker onset); this may lead to a subjective experience of greater strength than an equivalent oral dose.
