A newly developed analytical method characterized by its speed and sensitivity for the determinationof ketotifenfumarate (KTF) in pure and pharmaceutical preparation is established viaturbidimetricmeasurement (0-180o ) by Ayah 6SX1-T-1D Solar cell CFI Analyser. The method was based on the reaction ofphosphomolybdic acid with ketotifenfumarate in sodium chloride medium to form yellowish green precipitate as an ion-pair complex. Turbidity was measured via theattenuation of incident light that collides on the surface precipitated particles at 0-180o . Thechemical and physical parameters were studied and optimized. The calibration graph was linear in the range of 0.5-50 mMol.L-1 , with correlation coefficient r = 0.9976. The limit ofdetection 4.255 µg/sample fromthe step wise dilution forthe minimum concentration in the linear dynamic ranged of the calibration graph with RSD% lower than 0.7% for 9 and 20 mMol.L -1 ( n=6,8 respectively ) concentration of ketotifenfumarate. The method was successfully applied to the determination of ketotifenfumarate in two pharmaceuticals . A comparison was made between the newly developed method analysis and the classical method ,in addition to between twodifferentpharmaceutical preparations (UV- spectrophotometry at wave length 298 nm) usingthe standard additions method via the use of t-test. It was noticed that there was no significant difference between two methods at 95 % confidence levelandnosignificant difference between two drugs.
preparations (UV- Vis spectrophotometry at wave length 465nm) using the standard addition method via the use of t-test. It was noticed that there was no significant difference between two methods at 95 % confidence level & no significant difference for drugs (Ponstidin - SDI- Iraq and Ponamec-Mvc – India) and significant difference for drugs (piostan- pioner- Iraq and ponstan Pfizer-USA).
