The effect of patent expiration on sales of branded competitor drugs in a therapeutic class

DrugPatentWatch was used in a recent research study on branded drug sales following generic entry.

In this paper, authors Jeffrey Fujimoto, Daniel M Tien, Sophie Snyder, Jeppe A Hertz, and Stuart Schweitzer analyzed the effect of patent expiration of the first innovative drug in a therapeutic class on competitor sales within the same therapeutic class for five major therapeutic classes.

They found that sales volumes decreased by nearly 50% in the first year following patent expiration, and continued to drop to levels exceeding 60% in the following years. The also noted that the effect of patent expiration was not uniformly negative. In some cases competitors were often able to obtain dominant market share.
