Morphine and heroin also produced higher rates of euphoria and other positive subjective effects when compared to these other opioids. [47] The choice of heroin and morphine over other opioids by former drug addicts may also be because heroin is an ester of morphine and morphine prodrug , essentially meaning they are identical drugs in vivo .

Age and pain tolerance are relevant especially in the elderly because if their pain is detected too late, they run the risk of greater injury or delayed treatment of disease. However, current knowledge shows that pain tolerance does not show substantial change with age. [6] Only pain threshold shows an effect: it increases with age.
To the contrary, in rats, (+)-morphine acts as an antianalgesic and is approximately 71,000 times more potent as an antianalgesic than (−)-morphine is as an analgesic. [ 1 ] (+)-Morphine derives its antianalgesic effects by being a selective-agonist of the Toll-like receptor 4 (TLR4), which due to not binding to opioid receptors allows it to ...
Opioid-induced hyperalgesia (OIH) or opioid-induced abnormal pain sensitivity, also called paradoxical hyperalgesia, is an uncommon condition of generalized pain caused by the long-term use of high dosages of opioids [1] such as morphine, [2] oxycodone, [3] and methadone.
Opioids work on opioid receptors in the brain and other organs to produce a variety of morphine-like effects, including pain relief. [2] [3] The terms 'opioid' and 'opiate' are sometimes used interchangeably, but the term 'opioid' is used to designate all substances, both natural and synthetic, that bind to opioid receptors in the brain.

Endorphins may contribute to the positive effect of exercise on anxiety and depression. [43] The same phenomenon may also play a role in exercise addiction . Regular intense exercise may cause the brain to downregulate the production of endorphins in periods of rest to maintain homeostasis , causing a person to exercise more intensely in order ...
Miosis and reduced bowel motility tend to persist; little tolerance develops to these effects. [citation needed] The canonical MOR1 isoform is responsible for morphine-induced analgesia, whereas the alternatively spliced MOR1D isoform (through heterodimerization with the gastrin-releasing peptide receptor) is required for morphine-induced itching.
