It is all over the news in the past week that FDA has approved the first "digital pill" -- a sensor that can be attached to a pill and enter your digestive system when you take the pill. The approval is only for placebo pills for now so that the company can conduct clinical studies. So, what is the purpose of such sensor on pills? It is not to treat or even diagnosis any medication conditions. Instead, it is to verify that the patient has indeed taken the pill -- so that people who are not taking their pills can receive "reminders" to do so. That has certainly highlighted the big problem of medication compliance and the length people are willing to go in order to make a dent on that problem. However, I have always thought that adding a sensor to the pill with no other purpose than bugging patient is a little extreme. What do you think? Patients would certainly not pay more to take those pills if they have a choice between these and normal pills.
