Having a history as a child who got asthma regularly until puberty kicked in with a flood of extra hormones I'm still somewhat baffled as to why the old Docs never even once had me try any of the inhaler treatments. Can't forget the old Primatene Mist TV ad from the 70's.
Here's something I once picked up for novelties sake at a local swap meet where both expired OTC and non OTC prescription medications can often be found for pennies. Sometimes the bottles will actually have a name to whom the medications were initially prescribed to printed on them.
epinephrine = norepinephine = noradrenaline = the human body's own natively produced "speed"
I can see some confusion about there being a difference between ephedrine and epinephrine. Especially when their effect is so similar in the human body. Bronkaid's companion product to this one are asthma/broncodilator capsules whos active ingredient is ephedrine.
On a side note my father recently had abdominal surgery to correct something that occurred due to a mild hernia. When I picked him up from the OR he was still dazed in a post fentanyl haze. They were monitoring his vital signs to see if they thought he was stable enough to be released and they noticed that he began having an intermittant, somewhat odd heart flutter at about twice the tempo of where it should be.
I told them that is was most likely my father being socially conscious of being in the situation he was and that their concern for the problem was most likely a further and sustaining source for it. The attending nurses didn't seem to like this suggestion but when the surgeon came for his final check he agreed with me.
He said it could also be partially due to the epinephrine that he'd been given as a local anaesthetic? I knew they used pharma-coke in the form of lidocaine for this but I'd never heard of epinephrine being injected around the direct site of of incision as a local pain killer.
Oh well, I don't work in the medical industry so that's probably why it seems unfamiliar. (and why I also got my terminology wrong as Rhodium clarifies below)
