Abstract

The validation analytical method of the Lapatinib ditosylate assay is crucial to increase testing capability and capacity in strengthening the supervision of post-marketing drugs in Indonesia. A fast, precise, accurate, valid, and efficient test method is needed to carry out the test. A previous study on determining Lapatinib ditosylate assay generally used a C18 column, yet for efficiency, it is also necessary to develop a test method that can use existing resources in the laboratory, where the research used a C8 column. In this study, an analytical method to determine the assay of Lapatinib ditosylate developed using a High-Performance-Liquid Chromatography-Diode Array Detector (HPLC-DAD) system equipped with an autosampler and XBridge ® C8 column (Waters); 250 x 4.6 mm i.d. 5 μm. The mobile phase consisted of pentane-1-sulfonic acid sodium salt 10 mM - acetonitrile (65:35) eluted isocratically at a 0.6 mL/min flow rate. Detection was carried out at a wavelength of 222 nm. The analytical method was validated with test parameters of selectivity, system suitability, accuracy, precision, linearity, detection limit and quantification limit. Results from the validation study demonstrated a retention time of 4.63 minutes, good linear in the concentration range of 0.06 – 0.18 mg/mL with a correlation coefficient and Vx0 of 1.00000 and 0.1%. Test accuracy (% bias) obtained a value of 0.77% with precision (system, method and intermediate) less than 2.0%. The detection and quantification limits were 0.67 µg/mL and 2.02 µg/mL. Based on the research results, it can be concluded that the method developed provides fast, accurate and valid performance.
