ABSTRACT
Chemotherapy is the main treatment modality for certain types of cancer. It is important to monitor and ensure that these chemotherapeutic drugs are potent and effective prior to patient administration. The objective of the study is to evaluate the cytotoxic activity and potency of selected commercially available generic anticancer drugs in comparison with originator using various human cancer cell lines in an in vitro cell-based assay. Half-maximal inhibitory concentration (IC50) of the different chemotherapeutic agents was obtained from an experimentally derived dose-response curve. Relative potency of the drugs was estimated according to Parallel Line assay. This study demonstrated that the selected generic oncology products tested had similar efficacy compared with the originator. Both products showed comparable results as shown both in vitro cytotoxicity assay and statistical analysis. In vitro cell-based cytotoxicity assay promises to be a useful, reliable and rapid method for demonstrating chemotherapeutic drug activity.
