Thanks Angelo, the concept of preventing the pills from dissolving when too many are taken is scientifically possible. Odidi pulls this off, it's an amazing invention.
This is interesting it uses the same concept of some of the cancer drug that uses a linker that carries the drug through blood circulation and only release in the tumor area when acidic lvl increases naturally around and inside the tumor. In this case, when too many drug was taken it changes the condition so that the drug don't release. Sort of backwards of the same concept. Enclose the drug in something that could identify the condition for release or in this case change the condition to prevent drug release. Fascinating stuff.
It was almost a couple of years from the patent application to the patent publication and many times I wondered how it could be possible.
When I read the patent I had one of those "ha ha" moments... "why didn't I think of that"!
You don't get many of those moments in a lifetime.
