Spider venom key to pain relief without side-effects

—————————————————————————————————————————————

Molecules in tarantula venom could be used as an alternative to opioid pain killers for people seeking chronic pain relief.

University of Queensland researchers have designed a novel tarantula venom mini-protein that can potentially relieve severe pain without addiction. . . .

"Our study found that a mini-protein in tarantula venom from the Chinese bird spider, known as Huwentoxin-IV, binds to pain receptors in the body. . . .

Dr Schroeder said the mini-protein had been tested in mouse models and shown to work effectively. . . .

the spider sedates their victim, but then ingests the "poison" itself.
whats the effect on the spider? sleeps after eating a prey?

@roller - I don’t know. But hopefully, if this treatment works you will not need to keep a tarantula in your medicine cabinet. 😳🕷🕸😁

Another means of getting pain relief is to use nitrates. Most research is into transdermal glyceral trinitrate patches but the analgesic properties of nitrates seem to fly under the radar of most of the medical profession.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6017304/ Transdermal and Topical Drug Administration in the Treatment of Pain.
[Nitrates are mainly used in the treatment of ischemic heart disease. However, drugs forming this group also display analgesic and anti–inflammatory effects. It is known that exogenous nitrates stimulate the release of nitrogen oxide (NO) from endothelium cells. This substance is a very strong mediator in many systems, especially in the central and peripheral nervous systems.
It seems that NO exerts its action through the stimulation of an increase in the concentration of guanylyl cyclase, increasing the level of cGMP. NO may also activate sensitivity to ATP potassium channels and, in this way, activate pain relief in the periphery.
It was demonstrated that ointments or patches containing glycerol trinitrate (nitroglycerine) display analgesic efficacy in the following conditions: rheumatoid arthritis, ankylosing spondylitis, costochondritis, muscle–fascial pain, complex regional pain syndrome, bursitis, coccydynia, bone metastases, vulvodynia and venous leg ulcers.
There is data indicating that the local action of nitrates potentiates analgesic effects of “strong” opioids, which indicates that this effect is a result of nitrate absorption and because of their central mode of action. The use of nitrates may be especially useful in patients in whom, due to renal, liver, heart, and GI tract diseases, NSAIDs are contraindicated. The main adverse effect associated with a local application of nitrates is frequent headaches.]
