Therefore, most of the opiate-type analgesics in use today are either extracted from Papaver somniferum or synthesized from those opiates, especially thebaine. [10]
Opioids are among the world's oldest known drugs.

("Divine work is the easing of pain") [15]
Endogenous opioids (enkephalins, dynorphin, endorphin) do not bind specifically to any particular opioid receptor. Receptor binding of the opioid causes a cascade leading to the channel opening and hyperpolarization of the neuron. The opioid receptors have the following channel types: mu, K + channel; l delta, K + channel; kappa, Ca 2+ channel ...
Opioid antagonists remain the standard treatment for respiratory depression following opioid overdose, with naloxone being by far the most commonly used, although the longer acting antagonist nalmefene may be used for treating overdoses of long-acting opioids such as methadone, and diprenorphine is used for reversing the effects of extremely ...

From 2011 to 2021, prescription opioid deaths per year remained stable, while synthetic opioid deaths per year increased from 2,600 overdoses to 70,601. [24]
