In DFP – and all other quasi Newton methods for that matter – the function’s curvature is approximated by a finite difference. Specifically, WebDFP was assessed by measuring the metabolism of DFP in hepa-tocytes treated with DFP. DFH formation was significantly en-hanced in the DFP-treated cells. In vivo, treating rats with DFP at doses of 10 to 100 mg/(kgzday) for 13 weeks indicated that DFP induced its own metabolism. The C max and plasma drug area under
