ePrescribing in Sweden covers over 65% of all prescriptions. ePrescribing is a highly regulated process with a high demand on availability and security in a complex communication situation with many systems and actors involved. It is an interaction between two markets, healthcare and pharmacy. The purpose of this work is to con-tribute to the development of models to analyse e-services. Three models are used to analyse ePrescribing: the Generic Exchange Model, the Generic Regulation Model and a socio-pragmatic communication framework. The conclusion of this application is that the models contributed to new essential insights and helped to focus on es-sential communication aspects. The analysis contributes to a better understanding of ePrescribing in a general, to be useful both for those who are working with developing ePrescription, taking into account the different legisla-tion and history of prescribing in their countries, and for policy makers who may want to turn the process of ePrescribing into a new direction.
