Development and Validation of a Stability indicating HPLC Assay Method for determination of Ticlopidine Hydrochloride in Tablet Formulation

The objective of the current study was to developed simple, precise and accurate isocratic reversedphase stability indicating HPLC assay method and validated for determination of ticlopidine hydrochloride in solid pharmaceutical dosage forms. Isocratic RP-HPLC separation was achieved on a Phenomenex Luna C8 (2) column (250 mm ́ 4.6 mm i.d., 5 μm particle size) using mobile phase of methanolammonium buffer (80:20, v/v) at a flow rate of 1.0 ml/min 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 40-160 μg/ml with a correlation coefficient 0.9999. The precision (RSD) amongst sixsample preparation was 0.41 % for repeatability and the intermediate precision (RSD) amongst six-sample preparation was 0.61 %. The accuracy (recovery) was between 99.78 and 99.95 %. 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.
