Well, yeah, that's why they spend money to advertise them. If they were effective drugs, they'd sell well without any pushing.
There is separate physician marketing that is much more sophisticated.
Look at the FDA research on it including a survey of doctor on the impact.

“Most physicians agreed that because their patient saw a DTC ad, he or she asked thoughtful questions during the visit. About the same percentage of physicians thought the ad made their patients more aware of possible treatments.”
