- W2394231330 abstract "Aim The content of famotidine was determined using the RP-HPLC with comparison of ChP (2000 version) and USP (26 version). Methods The content of famotidine was determined using the RP-HPLC method The chromatographic conditions at the ChP included the C18 column and the mobile phase was composed of sodium heptanesulfonate (dissolve 2.0 g of sodium-heptanesulfonate in 900 ml of water and adjusted pH to 3.9 by acetic-acid, diluted with water of 1 000 ml)-acetonitrile-methanol (25 ∶6 ∶1). The detection wavelength was 254 nm. The chromatographic conditions at the USP included the C 18 column and the mobile phase was water-methanol-monobasic potassium phosphate buffer solution(31 ∶6 ∶3 and adjusted pH to 5.0 by acetic-acid). The detection wavelength was at 254 nm. Results The linearity was obtained over 0.0125～0.20 g·L -1 (r= 0.999 9 ) for famotidine at the ChP (2000 version) and the linear relation was good. At the USP(26 version) the linearity was obtained over 0.002 024 ～ 0.202 4 g·L -1 (r= 0.999 9 )and the linear relation was good.Conclusions The two linear relation was very good with the density and the peak area. But the USP compares with the ChP to the peak area is lower, but the cost of mobile phase is lower, safer." @default.
