I would say that in Sweden we have had this copayment system for a very long time, so I don't think I can really answer what the motives were in the beginning. Of course, the thresholds have been changed over time, so it's higher now than it was in the beginning, naturally.
I would say it's mainly a political ambition of affordability and equal access, but I would also say that it is clearly stated that it shouldn't be zero. It should be a copayment and it should be somewhat substantial, and that is because we can see that patients have a tendency to take out too much of the medicine if it's at no cost, and it's not used properly, so there are problems with compliance and medicines being thrown away. That's also a problem for the environment and so on.
