Some of us have had nasal antihistamines prescribed as part of the ana treatment . . . (after epi given) . . . so thought this was interesting.
But of course the Epi would be quickly absorbed in those nasal tissues.

whoah.
I think compliance rate would increase. I wonder if the temp ranges would be greater.
Glad you saw this ajas. It's one of the things I was thinking we need to be aware of. :)
I can't be the only one recalling a reaction, though, in which this would be, er-- well, useless, to put it bluntly... given the volume and rate of SNOT production going on.
No?
Just me, then. :hiding:

Exactly what I was thinking, and wondering how the increased swelling and congestion might impact efficacy.
Heck, if could be nasal spray, then why not an ORAL SPRAY? Talk about easy and convenient in many instances.
Would be quick absorption there as well? Is intra nasal faster than intra oral?
(And I know those "intra" words should be one whole word each, but the damn autocorrect wanted to make the second one into intraMURAL. GGA!!)
I can envision an epinephrine "kit" with both injectable and spray.
Sweet.
Very interesting! Nasal spray may not work with snotty reactions, but mouth sprays may not work well with swollen tongues or mucous in the mouth either. Could this also lead to sublingual spray? Again, not so great with a swollen tongue.
I don't think this would remove the need to carry injectable epinephrine, but it would certainly make it easier to treat reactions when excessive mucous or swollen tongue isn't present. :)
Intranasal is a distinct route of administration-- absorption through the nasal mucosa is different than sublingual. This is why people snort so many drugs rather than letting them dissolve under the tongue... (No, really!)
If the idea is to produce a dramatic SPIKE in plasma concentration, that is.

Ahem, I can think of another route of ingestion that might work as well... Though I imagine it would not be a terribly attractive option to most folks. :misspeak:
Carry on. ;D

Pretty sure DS1 would volunteer for that over a shot. DS2 likes needles :misspeak: And during the GB blow-up, DH got quite a bit of practice with the other route. He should be eligible for sainthood.
I can't see it replacing an injector but I'd certainly welcome carrying another back-up.
This could really be a great way of carrying a far more stable dose, too--
because it could really readily be packaged as a stable, N2-cushioned ampoule with solid Epi-HCl in a measured dose, just waiting to be smashed and shaken into a measured volume of buffered saline.
High temperatures and lows would be nowhere near the level of concern.
:thumbsup:
Is it sad I get excited about novel methods to carry epinephrine and Benadryl?

They do make an emergency seizure medication that is administered in this way. Had one camper who had it when I was a director.
Imagine explaining that to your co-workers.
Yeah, I was chuckling to myself earlier that man, we only THINK that it's tough to get bystander action with an Epipen...

:yes:
This is a real gem of an observation:
Quote
As a Canadian researcher, Paul M. O'Byrne, has pointed out, one of the biggest weaknesses with all medication is the fact that it doesn't get tested under real-world conditions until it is out in the real world at which point it runs smack into human behavior, not to mention varying phenotypes that respond differently to chemistry. One of those involved in this new nasal enterprise says, "Only a small fraction of diagnosed at-risk anaphylaxis patients carry an auto-injector, which is in part due to needle phobia and lack of training in their use. Our joint product promises to provide patients [and their families] with a needle-free alternative." I am just guessing, but I would say that needle phobia is a very small part of the picture.
The largest barrier, IMO, and based on anecdotal evidence from LAYPERSONS over the years-- is actually flipping that mental switch into the red zone. "Oh, this could result in death. Right. Epinephrine it is."
Denial is a VERY potent force there. I have no idea how you deal with that, other than deliberately setting up a scenario in which to USE epinephrine and see how rapidly it is effective-- which is obviously a horrifically bad idea under any circumstances whatsoever.
Pilots practice emergency scenarios and emergency procedures umpteen times as part of training the brain (& body) to go through the actions with less denial chatter and fear . . . for some/many pilos it works wonders, but for others they still freeze or go into "nah, it can't be THAT" as part of their calculus.
Human behavior still as unpredictable as anaphylaxis. Not good that we have BOTH working together when in the grips of emergency.
Besides needle phobia, there seems to be -- in teens for sure -- EMBARRASSMENT phobia. Don't want to call attention to myself or my medical predicament.
(Ambulance ride with bells and whistles? Cost and negative attention to self also factor in here . . . )
But I digress.
I'd sure opt for nasal epinephrine if available. Not sure if either of my kids would go for that given how bad they hate (refuse) other nasal sprays/drops.
Question: How about eyedrops? Would that work?
I don't think so, Ajas, based on what I know of administration routes.
It won't give the "pulse" of Epinephrine. There is a reason why stimulant drugs of abuse tend to be administered in one of two ways-- injected, or snorted.
One of the EMTs I chatted with in the truck (whee! so many ER trips) said he had seen some studies showing the dispersal of epinephrine from the force of the autoinjector was greater than that of a regular syringe. But you all know how I feel about delivering hearsay. What comes to my mind in nasal spray is did I get it in? Did it puff in enough? What if I miss? Would I overdose accidentally? I guess I get more concerned dosing someone else than myself because I could feel the spray.
CM, understand . . . drops into eyes not being snorted/inhaled up to the top of nose and quick-entrance to brain cavity. Just wasn't sure how much tissue absorption could be counted on with eyes vs snort/inhale via nose . . .
tt -- after reading what you wrote, sounds to me like injection into side of thigh might produce the most "standard" release and response to epinephrine -- not dependent on effectiveness of the inhalation . . . hadn't really thought about that.
But still.
It is GOOD to see the medical establishment (and perhaps fringes too) rethinking mode of imparting epinephrine to the patient.
Investigation and improvement is good. All good.
