title: Simultaneous determination of ritodrine and isoxsuprine using coupling technique of synchronous fluorimetry and H-point standard addition method.
abstract: Simultaneous determination of two structurally related ss(2) adrenergic receptor agonists namely, Ritodrine HCl (RTH) and Isoxsuprine HCl (ISP) was performed using coupling technique of synchronous fluorimetry and H-point standard addition method. Under optimum conditions, linear determination ranges were 1.48 - 14.80 x 10(-6) mol L(-1) and 1.54 - 15.44 x 10(-6) mol L(-1) for ISP and RTH respectively. RTH and ISP could be determined simultaneously without interference from each other when their concentration ratio varies from 5:1 to 1:5 in the mixed sample. The proposed method was applied to the determination of RTH and ISP in synthetic mixture of pharmaceutical samples, the accuracy and precision of the results were satisfactory.
