Abstract

Background: Breast cancer (BC) has become the most common cancer among women in India. Both amlodipine, belonging to calcium channel blockers, and nebivolol, belonging to the beta blockers class have proven anticancer mechanisms. However, the effect has not been compared between these drugs till now.

Aim and Objectives: The present study aims to compare the antiproliferation effects of amlodipine and nebivolol against human breast adenocarcinoma MCF-7 cells.

Materials and Methods: Cell viability assay was used to screen the antiproliferation effects of the study drug molecules in MCF-7 cell cultures. The IC50 values were derived graphically by plotting the cell viability against drug concentration.

Results: Both amlodipine and nebivolol exhibited dose-dependent cytotoxicity against BC cells. The IC50 of amlodipine was 166.6 μg/mL and nebivolol was 114.6 μg/mL.

Conclusion: In this study, nebivolol showed potent cytotoxicity compared to amlodipine. This inference may provide further insights into future drug research.
