A significant drawback of modern drugs is that they are designed for an abstract average patient. That is, we are talking about millions of people of different ages, with different physiological characteristics, using the same tablets. Not surprisingly, the effect of their application for everyone is completely different: they help someone, others, on the contrary, are harmed.

Researchers at the University of Copenhagen together with colleagues from the Academic University of Abo (Finland) are convinced that the future is for targeted, individual treatment. The tablets they have developed consist of an "edible" substrate with a QR code applied to it.

To print the code, a conventional inkjet printer with ink consisting of lactic acid, ethanol and food dyes was used. The substrate also consists of fully edible pyrogenic silicon dioxide, glycerol and methyloxypropylcellulose.

In accordance with this technology, doctors will enter into the QR-code all the necessary information about a particular patient, for example, his name, dosage, serial number, instructions for use.

"Address" tablets will help doctors to monitor the taking of medications, the QR code of which the patient scanned before using it using a smartphone.
