Study sample of high-cost drugs.

*Totals are in 2008 Australian dollars. The cumulative costs should be interpreted in light of the fact that the study window caught drugs at different points in their commercial life cycle. Some drugs (e.g. Glyceryl Trinitrate) were being marketed before 1991; others (e.g. Felodipine) were not approved for marketing until later in the 1990s.
