A survey of the effects of a drug promotion campaign

A postal survey which tried to test the impact of a drug-promotion campaign is described. One hundred and twenty randomly-selected general practitioners were circulated and a 74.8 per cent response was obtained. Of the responders, 92 per cent were aware of the existence of the preparation, and of these responders 69 per cent were unaware either of the pharmacologically approved name of the drug, or the fact that its pharmacologically active constituent was already available under another brand name.
