The Pryor-Cohen letter Text of the Aug. 10 letter from Sen. David Pryor, D-Ark., and Sen. William Cohen, R-Maine, of the Senate Special Committee on Aging, to Jorge Engel, president and CEO of Berlex Laboratories.

The lawmakers appended four questions arising from prior contacts with the company, which Berlex said it intends to answer this week. The questions are not included here because the context is not clear. However, they relate to the amount of drug covered by the price, Berlex's net revenue and profit per patient, the role of pharmacists and the prospects for deferred billing.

Dear Dr. Engel,
