| dc.description | Tirofiban hydrochloride was subjected to the degradation under conditions of hydrolysis (acidic and alkaline degradation), oxidative, thermal and photolytic degradation as prescribed by ICH. A simple and precise liquid chromatographic method has been developed and validated for the simultaneous determination of tirofiban hydrochloride monohydrate (TIR) and its synthetic starting material; tyrosine (TRS). All the chromatographic separations were achieved on Zorbax SB C18, 250 mm×4.6 mm i.d., 5μm column at a flow rate of 1 mL min−1. Isocratic elution based on 0.1 M phosphate buffer (pH 3) - acetonitrile (70:30, v/v) with UV detection at 227 nm was applied. For the stability study separation of TIR from its degradation products was achieved using 0.1 M phosphate buffer (pH 3) - acetonitrile (72:28, v/v) with UV detection at 210 nm. Method validation parameters namely, linearity, accuracy and precision were found to be acceptable over the concentration ranges of 10-250 μg mL-1 for TIR and 1-70 μg mL-1 for TRS. The minimum detection limits were 1.76 μg mL-1 for TIR and 0.13 μg mL-1 for TRS. The optimized method was validated and proved to be specific, robust and accurate for the quality control of the cited drug in drug substance and drug product. | en-US |
