What if you allow basically the same ad but disallow mention of any brand names - only the generic name or condition to be treated?
Honestly though, it's a good system. I can't actually tell you what brand that ad is for, but I do know that I can talk to my doctor about it if I have issues with PE!
Also, I imagine that the cost of making and running the commercial would be pretty trivial compared to the profits to be made from the sale of the product.
