Drug innovation is not in the doldrums: study

Since 1971 there have been troughs and peaks in new chemical entities and new biological drugs coming to market, the study found.

The pipeline slowed to a trickle in 1985, with only nine new drugs introduced but this climbed to a high of 34 in 1997 and again in 2010.

Overall there was a slight increase in introduction of new drugs of 0.16 per year over the four decades, suggesting trends should be viewed long term to gain an accurate picture of the industry’s health, the researchers said.
