Non-adherence on medication is increasing and there are several problems associated with it. There are many challenges in order to have full adherence to the prescribed treatments. Smart pill dispensers are being a new way to support patients who have complex prescriptions. However, those dispensers do not have much capacity and are very simple machines with few components. This paper presents a new architecture for smart pills dispensers based on Events-Driven, a distributed architecture where all the components have weak associations with each other. This architecture proves to be very advantageous for smart pill dispensers, increasing the flexibility and the resilience of these machines.
