Serum uridine levels in patients receiving N-(phosphonacetyl)-L-aspartate.


Serum uridine levels of N-(phosphonacetyl)-L-aspartate-treated patients from Phase 1 and continuing trials receiving 1000 to 2000 mg/sq m/day were measured by reverse-phase high-pressure liquid chromatography. For the five patients studied, the predose serum levels ranged from 2.6 to 64. microM, well within the normal range of 1.9 to 8.9 microM. All serum… (More)
