New pain relief is eight times stronger than morphine
telegraph.co.uk — A groundbreaking treatment for pain that is eight times stronger than morphine has been discovered by scientists. The revolutionary technique involves an injection that can combat serious discomfort for more than three days - 14 times as long as morphine.

"appears to have few side effects and works by neutralising the chemical in the body that causes the brain to feel pain."
Makes me think that it's not. Morphine works because it stimulates a part of your brain to create chemicals that lessen pain, this seems to neutralize the chemical that causes it in the first place. The fact that it actually neutralizes the chemicals secreted by cells when you're in pain furthers this because, don't quote me on this, but I don't think someone could be addicted to the neutralization of a chemical that is only created when they're in pain. I mean, if it's not in the bloodstream in normal circumstances, the drug shouldn't have much of an effect when a patient takes it when they're not hurting.
I could be totally wrong though. I'm nowhere near a doctor.- isunktheship, on 10/09/2008, -0/+25Side effects may include: ***** AWESOME.
- charlietuna, on 10/09/2008, -0/+1Pop-mech loves everything new. They are never unbiased.
- Casserole69, on 10/09/2008, -0/+6Initially I would say it should be less addictive as well because of what you just said. But, because it neutralizes pain causing chemicals, the body may adapt by increasing the amount of chemicals it synthesizes for pain. Therefore hyperalgesia would probably be a side effect. If hyperalgesia is a side effect, then the person would probably not want to stop taking the drug.
- fadetoone, on 10/09/2008, -3/+26Is it heroin? It's heroin, isn't it?
- Elizle, on 10/09/2008, -3/+3Heroin is synthetic morphine.
- whywait, on 10/09/2008, -3/+23ur synthetic morphine.
- kcap122, on 10/09/2008, -0/+9Wrong. Heroin is chemically modified morphine. Specifically, acetylation at the two benzyl hydroxyl groups.
- TrancePhreak, on 10/09/2008, -5/+4everything is addictive.
- AThoughtOrTwo, on 10/14/2008, -0/+1Breathing is, so is eating, sleeping - a bunch of things.
- DiggzDE, on 10/09/2008, -6/+3Marijuana?
- kcap122, on 10/09/2008, -1/+5No, it's not. The method of action for most painkillers (besides the anti-inflammatories like advil, aspirin, etc) is to activate opiod receptors in the brain. Opiod agonist drugs cause temporary changes that make it harder for neurons to release the "pain signal,": PAP. They also cause the release of dopamine from the same neurons. As a result, you get two effects: diminished sensation, and pleasure. So when it wears off, the nerves overcompensate and can cause withdrawal effects, or compulsion to find more of the drug to continue the dopamine release.
This new class of drugs doesn't enter or interact with nerves in any way. They block PAP from performing its job once it's released by binding to it, or competitively bind PAP receptors. I know that there is also some ongoing research into downregulation of PAP production, but I don't think that's come anywhere near legitimate yet.- kcap122, on 10/09/2008, -1/+1yah sorry correcting myself here, kept saying PAP after i read the article, but meant this thing i forgot the name of, "molecule P" or "factor P" or something
edit: substance p. woot. - bobfell, on 10/09/2008, -1/+2This is not a new class of drugs, it is research into the basic cellular mechanisms of neurons in the brain. PAP is not a signaling molecule with receptors, it is an enzyme that converts a pain signaling molecule, AMP, into a pain suppressing molecule adenosine.
That is why Mark says in the article he hopes to find a way to modify it for oral delivery. As is, it has to be injected with a needle right into the specific nerves that you want to inhibit.
That would be like a nerve block which takes a skilled anesthesiologist to administer.

- newms32, on 10/09/2008, -0/+2Short answer: No
Long answer: Opiates produce pleasure by directly acting on mu opioid receptors on inhibitory neurons that project to an area of the brain called the ventral tegmental area (VTA). The VTA (along with the nearby nucleus accumbens) is responsible for the rewarding effects of many abused drugs such as amphetamine, cocaine and opiates. When the opioid receptors on these cells are activated, their firing is inhibited, but since they're inhibitory cells this results in an increase of activity in the VTA. This is perceived as pleasure and the resulting dopamine surge causes the behavior to be reinforced in subconscious memory in a way similar to how someone can learn so well about something they're excited about. Along with tons of other factors, this can lead to addiction.
The treatment in the article works by getting rid of a chemical that causes pain (probably Substance P but I haven't looked it up). This bypasses the opioid system, so there won't be the reinforcing effects of opiates unless there's some weird roundabout mechanism that I don't know about.- Niightwitch, on 10/09/2008, -0/+1Ah...the elusive Substance P.
- bipolarruledout, on 10/09/2008, -0/+2Heroin was invented by Bayer in the first place because it was believed to be less addictive than morphine.
- newms32, on 10/09/2008, -1/+2To be fair, it is damn good at getting rid of a cough.
- snached, on 10/09/2008, -0/+1Yep. It used to be sold in those cute little Bayer glass bottles.
- jeffsback2223, on 10/09/2008, -0/+1Could be 8 times as illegal as well D:
- rakaur, on 10/10/2008, -0/+1Large animal tranquilizers are derived from fentanyl. Carfentanil is around 10,000 times the potency of morphine.

- Hetman, on 10/08/2008, -3/+84Damn I have seen so many stupid ass Palin articles on digg. When I read the title I thought it said "New Palin relief"
- RgyaGramShad, on 10/09/2008, -3/+20I think we all need some Palin relief after seeing so much of that ***** on digg…
- Hockey13, on 10/09/2008, -3/+3A few stories in the past few days have had the word "pain" in their titles. Every time I see that word on Digg, my mind reads "Palin." Strange.
- DMCer, on 10/09/2008, -0/+3Um, that's already been said.
- mrfunktastic, on 10/09/2008, -0/+1I can't believe you've done this.
- nitsnipe, on 10/09/2008, -4/+2Same here, I almost expected something about Palin being 8 times stronger than McCain.
- VitriolAndAngst, on 10/09/2008, -3/+2Well if it's Palin Relief -- I'll take three, please.
- cloudberries, on 10/09/2008, -2/+7Well, I'll have a whole pack. And an extra shot of McNovocaine
- SpectralSounds, on 10/08/2008, -2/+14I just to be prescribed fentanyl patches. Fentanyl is 81 times stronger than morphine. The patches lasted for 72 hours. So pain killing wise, I'm sure the patches are at least comparable to this new drug. But, I had some crazy ass side effects though. So, less side effects and less dependance would be a good thing if that what this new drug is capable of.
Quiting and withdrawing from serious opiate addiction is no fun whatsoever.- SpectralSounds, on 10/08/2008, -0/+9Obviously all those drugs screwed with my head. I meant to type, "I used to be prescribed...." I'm losing my mind.
- JoshuaGross, on 10/09/2008, -0/+2Holy... 81 times?
In related news, I know a guy who has an overactive liver and the highest legal dose of morphine has no effect on him. I wonder if Fentanyl would work. - connieLingus, on 10/09/2008, -0/+3ahh yes the american way...do new drugs to get off old drugs.
- secrity, on 10/09/2008, -0/+2It is not an opiate and there are people who cannot tolerate opiates.
- FTG1, on 10/09/2008, -1/+1You can chew on those fentanyl patches and it ***** you up for ~8 hours. Depending on your dosage if it's 100 mcg you can stretch that 3 days out till at least a week ;)
- shotgunefx, on 10/09/2008, -0/+1And the messed up thing is that for some cases, it still doesn't do enough.
- elliotys, on 10/09/2008, -0/+1Lets not forget levorphanol. It's 100 x times as potent as morphine.
- gahal, on 10/09/2008, -0/+1All I could think of was fentanyl when I read the headline. I have heard different figures of the potency, from 20x to 80x more potent (per mg) than pure heroin. Keep in mind that fentanyl is normally prescribed in micrograms and not milligrams like most pain killers.
I had a friend that died from a massive OD of fentanyl when he cut open a 3-day patch and ate it. He was an idiot so it was only a matter of time.
When I was young, I used to try lots of different drugs. I only ever injected once though. That night I thought I was trying morphine out of an opened patch. It turned out it was a fentanyl patch that someone had mistaken for a morphine patch. I thought I was dead. For days I was unable to even sit up for more than 30 seconds without starting to faint. It had my heart beating so softly that I was unable to even register a pulse. I could not feel my own heartbeat, and when I had people try to check my pulse they could not find one. I even had some friends try, two that were phlebotomists and one that was a nurse. Of course my heart was still beating, it was just beating so slow and softly that it was very hard to feel via touch.
I have worked with a few people that were prescribed fentanyl lollipops. One of them had Multiple sclerosis, and the lollipops worked wonders for her. She would just suck on it till she was able to function and then would put it away. Far better than a patch, since they could stop ingesting the drug once they had enough.
- NikoKun, on 10/08/2008, -7/+38I'm sure this will be greatly abused, and also have many horrible side effects...
And yet meanwhile a relatively harmless pain reliever like Cannabis, is one of the most illegal drugs out there... -_-- madwaxer, on 10/08/2008, -1/+9The FDA █████ sucks!

oh sry nvm - JDLamb88, on 10/09/2008, -8/+3THC is legal, you can get it in pill form. You just want to smoke weed, hippy.
- kingmanic, on 10/09/2008, -1/+2Absorption rates differ greatly. Studies are on going.
- elliotys, on 10/09/2008, -2/+2Actually Marinol, the pill form of THC has little to no efficacy. The marijuana plant has numerous active cannabinoids that have yet to be isolated, so smoking it, unfortunately for your lungs, is the only way to get any benefit from it.
- gahal, on 10/09/2008, -0/+1Eating works better than smoking for chronic pain management. (that is of course for actual marijuana, not for Marinol). Just make sure it is heated first (cooked with food works for that part).
Eating yields a slower absorption rate, and also a higher overall absorption. This causes less of an instant effect, but a more effective long-term one.
And as a sidenote... Marinol is a joke. It fails on everything that real marijuana works on. Talk to anyone that has taken it.
- OffPiste, on 10/09/2008, -6/+6***** Obama and his anti-weed campaign. Yeah he smoked when he was younger but now he wants to increase enforcement AND continue the current anti-hemp laws.
- kevlar21, on 10/09/2008, -0/+3At least he won't raid medical patients. At least I think I remember him saying that…
- wreckosaurus, on 10/09/2008, -0/+5Anti-weed campaign? Oh shut up, you got any other ***** stories you want to pull out of your ass. You're a right wing troll, and you're very transparent. I see you've recently shifted to trying to pretend to be an Obama supporter:
Old offpiste: "Max this libtard out." "Barrack Hussein Obama. nuff said."
New Offpiste (on the subject of veteran suicide): "Good!! They were probably going to vote for McLame. The overwhelming majority of active duty and vets vote Rethuglican. Less votes for McBush means fewer votes for Obama are needed for him to have a victory come November. Vote Change Vote Obama"
- Hobbes24, on 10/09/2008, -5/+4ok maybe i just don't smoke enough weed to know, but how well does weed relieve pain? because i find it very hard to believe it does a better job than opiates
also, my assumption is that if medical weed were legal, it wouldn't get prescribed for pain simply because it has the very potent and obvious side affect of, well, getting you stoned.
now i know you can say you get high off of opiates too, but that's different, when your on painkillers all that really happens to you (usually) is that your in a good mood (i took medical painkillers for 6 months at one point).
now compare that to getting high, getting high is a MUCH more drastic change in personality and consciousness i know withdrawal from weed is almost non-existent, and from opiates is can be a killer, but i still think they are better for pain
and now, as i've talked in a slightly negative light about marijuana on digg, i shall prepare to be buried into oblivion- JaronDiggGuy, on 10/09/2008, -4/+4Buried for doing that *****, whiny, "I know I just spouted what I think is an unpopular opinion so I know I'll get dugg down now" *****.
- Hobbes24, on 10/09/2008, -0/+3^ well maybe i wouldn't say that if it wasn't true 99% of the time
- shotgunefx, on 10/09/2008, -1/+1As far as a pain killer, it's really not, it may help with muscular pain, and aches, but I don't think anyone is advocating giving you a joint for a broken bone, but it has plenty of beneficial side effects, against glaucoma, nausea control (chemo), anti-anxiety, and increasing of appetite for people who are failing to thrive (AIDs, cancers, etc). I don't think
And no, opiates, especially if abused (which they are all the time) are hugely addictive. And I'll tell you right now, percs, etc can alter your mood just as much as grass. I suppose it depends on the person and the dosage, but I've seen people on percs and oxys doing the "heroin nod" - Hobbes24, on 10/09/2008, -2/+1-shotgun
...i said opiates are very addictive
and i still think it's far easier to tell if a random person is on weed than painkillers, just the way they look, and more importantly the way they talk
but then again that's just my own experiences, maybe i haven't been with enough people who have done tons of either - bobfell, on 10/09/2008, -1/+1I call *****, I was a stoner for years and I could go get high right in the middle of a shift and with a little visiene, no one had a clue. That includes taking tables of 10+ peoples orders without writing anything down.
Painkillers... no can do! Well what are you talking about? NSAIDs? Opiates, no way. - yournightmare, on 10/09/2008, -1/+1bobfell, that's just your experience. I can function normally on high doses of opiates, but if I take one hit of low-grade ***** I'm totally worthless. Not everybody responds to the same drugs the same way you do.

- newms32, on 10/09/2008, -0/+1The whole point of this is to make a painkiller that doesn't have the side effects that all current opioids have, including hydromorphone. Potency isn't a motivating factor at all, we already have etorphine (elephant tranquillizer) which is roughly 10,000x the potency of morphine. You need to adjust the dose before any opioid is taken; one that's 8x as potent will need to be given at 1/8th the dose to avoid overdose.

- TheCollective00, on 10/09/2008, -1/+1"The study published in the journal Neuron involved injecting the protein prostatic acid phosphatase (PAP) into the spines of genetically modified mice who were in serious pain."
Kinda makes you wonder how the scientists caused the mice such pain, doesn't it?- newms32, on 10/09/2008, -0/+11. Hot plate test - set the mouse on a hot plate and time how long it takes to lift their paws and lick them, which is the normal response to heat (a few seconds)
2. Tail flick assay - dip the tail in water that's borderline hot-to-the-touch and time how long it takes them to flick their tail out (again a few seconds)
3. Acetic acid test - inject dilute acetic acid (vinegar) into the intestines and judge analgesia based on behavioral response
There are some variations but those are the most common. Before everyone rushes in to denounce the cruelty, the tests are limited to certain time frames to prevent tissue damage from occuring. If the analgesic is so powerful that the mouse won't remove its tail from the water at all, the test is stopped well before damage would occur.
So yeah, they're in pain, but it's not Guantanamo Bay or anything.- TheCollective00, on 10/09/2008, -0/+0I can accept this. Thanks for putting my conscience at ease.

morphene is already addicting just like oxycotton- rakaur, on 10/10/2008, -0/+1Are you a retard?
Oxycodone (the active ingredient in OxyContin) is about equal to morphine in terms of potency. There is a difference between dependency and addiction.
Also, the whole point of this article is that it provides pain relief on a higher scale than morphine and it's *not a narcotic*.
