A simple and rapid differential pulse polarographic method has been developed for the trace determination of dexamethasone sodium phosphate. A well-defined single peak with an Ep value of -1.14 V is obtained in acetate buffer (pH 5.0). The linearity is valid in the range 0.2-1.2 mg/25 mL ( r=0.9992)
