Abstract:RP-HPLC chromatographic method was developed for determination of Hyoscine Butyl Bromide (HBB) and Dipyrone (DIP). In this method, HBB and DIP were separated by using C18 (25 cm×4.6 mm i.d. 5µm particle size) column as a stationary phase and using water: methanol (50:50) v/v pH adjusted to 7.0 with triflouroacetic acid and triethylamine) as a mobile phase, maintaining the flow rate at 1.0 mL min −1 with UV detection at 210 nm. The proposed method was successfully applied for determination of HBB and DIP in pur… Show more
“…Metamizole is a pro-drug, which spontaneously breaks down after oral administration to structurally related pyrazolone compounds [1]. Several methods have been reported for determination of dipyrone either alone or in combination with other drugs; these methods include HPLC [2][3][4][5][6], spectrophotometry [7][8][9] and Rp-TLC [10].…”
