Yeah, I went a little crazy there with my dream pill, and I didn't need to. This development, itself, is awesome. A antivenom for both hemo and neuro toxic venom! In a pill! How awesome is that?! It will make possible the mass production of antivenom. That will make it readily available and bring the price down.
I think India has the largest number of snake bite deaths in the world. This would allow local medical providers there to begin treatment before sending the patient on to hospitals for treatment. Imagine how many lives will be saved! Closer to home, these could be kept in first aid kits. You're kid gets bit by a copperhead in the woodpile? You could begin treatment right there. It sure would make the drive to the emergency room a lot less harrowing. Hikers could carry it with them. I don't know if hots keeper keep antivenom on hand, but this would make it easier, and so, keeping hots safer.
So, even if it never become a cure all, it has the potential to make already rare snake bite deaths even more so, and that's exciting to look forward to.
