After you gave me the hint. Otherwise I wouldn't have guessed.
Although I have some experience in this therapeutic area, I don't have time to follow everything I work on on a day-to-day basis. I've worked on 83 different drugs and 18 launches or label extensions over the past four years, so as you might expect data tends to go in one ear and out the other shortly thereafter. Hence the reason I couldn't remember that 1000 mg was a normal daily dose for naproxen.
