Abstract
The research and development costs of 68 randomly selected new drugs were obtained from a sur-vey of 10 pharmaceutical firms. These data were used to estimate the average pre-tax cost of new drug development. The costs of compounds abandoned during testing were linked to the costs of com-pounds that obtained marketing approval. The estimated average out-of-pocket cost per new drug is US$ 403 million (2000 dollars). Capitalizing out-of-pocket costs to the point of marketing approval at a real discount rate of 11% yields a total pre-approval cost estimate of US$ 802 million (2000 dol-lars). When compared to the results of an earlier study with a similar methodology, total capitalized costs were shown to have increased at an annual rate of 7.4% above general price inflation. © 2003 Elsevier Science B.V.

1. Introduction
Innovations in the health sciences have resulted in dramatic changes in the ability to treat disease and improve the quality of life. Expenditures on pharmaceuticals have grown faster than other major components of the health care system since the late 1990s. Consequently, the debates on rising health care costs and the development of new medical technologies have focused increasingly on the pharmaceutical industry, which is both a
