So Express Scripts ($100B in annual sales) is going to get taken out by unit dose packaging? WalMart's pharmacy is also testing blister packs + multi-dose...I don't see how this displaces ESI...
I would imagine that the ideal scenario is someone designing completely automated equipment for dispensing pills, verifying the pill visually via OpenCV or other computer vision software and packing the pills in a box ready for delivery. This would do the same for mail-order medication as Kiva did for Amazon warehouse automation.
My guess is that they'll get bought out if it takes off. Other pharmacies will copy the process.
