How can I locate pharmaceutical sales or use data for individual drugs?

I am hoping to locate present and historical sales or usage figures for various prescription drugs, and I am not sure where to start. I'm trying to use the data to get a sense of how many people were using a particular drug at different times; I just figured sales volume would be a good indication. For me, rough numbers would be fine. Paying for the data may be an option (especially if it is not too expensive), but I was hoping to find some good free resources. Any help would be greatly appreciated. Market share data for different drugs in a particular class would be similarly useful, especially to the extent that I can also find overall sales or use volume for the overall drug class.
