This study builds upon the current published work by
providing environmental fate data on 3 Pfizer products (Table
1). The objective was not only to satisfy our regulatory
obligations for these drug candidates, but more importantly
to (1) publish the environmental fate results on pharmaceuticals
in an area that historically has not been well
presented, and (2) provide recommendations as tohowbetter
implement the OECD 308 (17) guideline for assessing the
aerobic and anaerobic biodegradation of pharmaceuticals
in the context of the EU ERA testing guidance.
