The two more modern drugs show a different pattern. Aspirin shows that after the<br />

initial reports that there was a relative lull during the 1910s and 1920s followed by a<br />

more active period, only for reports to fall off again in the 1970s. The advent of<br />

paracetamol in 1956 and ibuprofen in 1962 caused a diminution in Aspirin sales, but<br />

it picked up again after its anti-coagulant properties were found in the 1960s. The<br />

new uses of Aspirin have enlarged the market yet again. The fall off of reports after<br />

1960 probably means that all its adverse effects were then known.
