Quantitative nondestructive methods for the determination of ticlopidine in tablets using reflectance near-infrared and Fourier transform Raman spectroscopy

Development and validation of a stability indicating UPLC method for determination of ticlopidine hydrochloride in its tablet formulation

The objective of the current study was the development of a simple, precise and accurate isocratic reversed-phase stability indicating Ultra Performance Liquid Chromatography [UPLC] assay method and validated for determination of ticlopidine hydrochloride in solid pharmaceutical dosage forms. Isocratic separation was achieved on a Zorbax SB-C18 (50 mm × 4.6 mm, 1.8 μm) column using mobile phase of methanol-0.01 M ammonium acetate buffer, pH 5.0 (80:20, v/v) at a flow rate of 0.8 ml min(-1), the injection volume was 4.0 μl and the detection was carried out at 235 nm by using photo-diode array detector. The drug was subjected to oxidation, hydrolysis, photolysis and heat to apply stress condition. The method was validated for specificity, linearity, precision, accuracy, robustness and solution stability. The method was linear in the drug concentration range of 62.5-375 μg ml(-1) with a correlation coefficient of 0.9999. The precision (relative standard deviation - RSD) of six samples was 1.31% for repeatability and the intermediate precision [RSD] among six-sample preparation was 0.77%. The accuracy (recovery) was between 98.80% and 101.50%. Degradation products produced as a result of stress studies did not interfere with detection of ticlopidine hydrochloride and the assay can thus be considered stability indicating.
