In my opinion the answer to this question is YES but in the context of developing countries only. As in most of these countries it is not mandatory to have doctor's prescription to buy medicine.

Thanks Dr.Asmat & Dr.Shafiq

I assume NO. Consumers here in country like India trust the doctor more than the medicine and many patients wont even know the name of the medicine. In countries where you have more conscious consumers, this way of promotion may work.

Hope this was helpful.

answewr from Asmat Ali is not only self-centered but also conceited;

What actually DTCA helps is to informing audiences with the existence of new treatments, which is necessary for people world wide;

So that anyone is able to take quick-respond to some slight illness; Consumers were somehow taught as well as advertised;

Although in some casesit would greatly influence the patient-doctoe dialogues;

I consider DTCA as a two edged blade;

By the way, there are only 2 countries in the world that actually permittin the DTCA forms of advertising, New Zealand and USA;

So, hopefully my answer could be useful because I just finished my report in my final year project, and the answers above are unbearable;

SO my answer to this question is, it depends whether the investment which mabufacture spend could fulfill the need of propagating this drugs;

It s a econ and PRA issue;

Yes it is, but as pharmaceutical products are like double edge sword which require art of weighing of benefits vs risk so less likely.
