The data suggest that entry barriers have fallen over time for new drug introductions. The increased competitiveness of the pharmaceutical marketplace was likely fueled by changes over time on both the supply and demand sides. The development histories of entrants to new drug classes suggest that development races better characterise new drug development than does a model of post hoc imitation. Thus, the usual distinctions drawn between breakthrough and 'me-too' drugs may not be very meaningful.
