People may be surprised, but drugs, even really good drugs, need to do some marketing. You can argue over what level of marketing is appropriate, but if you had a great drug and didn't do marketing, you'd take a huge hit to revenue.

I've talked to a handful of doctors who actually appreciate their sales rep. That usually happen when the rep tones down the sales routine and focuses more on helping the doctor do their job.
