The following table lists opioid and non-opioid analgesic drugs and their relative potencies. Values for the potencies represent opioids taken orally unless another route of administration is provided. As such, their bioavailabilities differ, and they may be more potent when taken intravenously. [citation needed]
"Pain ladder", or analgesic ladder, was created by the World Health Organization (WHO) as a guideline for the use of drugs in the management of pain. Originally published in 1986 for the management of cancer pain , it is now widely used by medical professionals for the management of all types of pain .
An analgesic drug, also called simply an analgesic, antalgic, pain reliever, or painkiller, is any member of the group of drugs used for pain management.Analgesics are conceptually distinct from anesthetics, which temporarily reduce, and in some instances eliminate, sensation, although analgesia and anesthesia are neurophysiologically overlapping and thus various drugs have both analgesic and ...

Morphine is the prototype of opioid analgesics [1] [3] Propranolol is the prototype of the beta blockers [4] [5] Chlorpromazine is the prototypical phenothiazine antipsychotic [6] [7] Imipramine is the prototypical tricyclic antidepressant, and itself a derivative of chlorpromazine [6] [8] Diazepam is the prototype of the benzodiazepine [2] [9]
Mechanism of action: Hydrocodone acts primarily as an agonist at the mu-opioid receptors, but is also a weak agonist against the delta opioid and kappa opioid receptors. [ 15 ] Absorption/distribution: The oral formulation can be absorbed from the gastrointestinal tract and remain 20–50% bound to plasma proteins. [ 15 ]
As the opioid pain meds became scarce, a cheaper opioid began to take over the market — heroin. Frieden said three quarters of heroin users started with pills. Federal and Kentucky officials told The Huffington Post that they knew the move against prescription drugs would have consequences.
For example, the supraspinal analgesic properties of the opioid agonist morphine are mediated by activation of the μ 1 receptor; respiratory depression and physical dependence by the μ 2 receptor; and sedation and spinal analgesia by the κ receptor [citation needed].
