An anonymous reader writes "The idea is simple — load up a microchip with a whole pharmacy of drugs that are dispensed as needed automatically. The devil has been in the details, since mistakes could kill the patient if, say, a leak developed dumping dangerous cocktails into the bloodstream. This MIT sponsored company, however, claims to have perfected wireless control of a pharmacy-on-a-chip and has just completed the clinical trials to prove it. The test microchip has just 20 doses of a single drug, but their new prototype will house thousands of pin-prick sized drug reservoirs, after which they will seek FDA approval. The elderly (who have complicated drug regime) and soldiers could both benefit from these smart pharmacies-on-a-chip, since drugs can be dispensed even if the patient is unconscious."
