CADILAP 250mg Tablet 30’s

INTRODUCTION

CADILAP 250MG contains Lapatinib which belongs to the group of medicines called antineoplastic agent. It is used to treat HER2-positive breast cancer which have spread beyond the original tumor or to other organs (advanced or metastatic breast cancer). HER2-positive breast cancer is a breast cancer that tests positive for a protein called human epidermal growth factor receptor 2 (HER2), which is capable of promoting the growth of cancer cells. Lapatinib is generally prescribed with other anti-cancer medicine like capecitabine, trastuzumab (for patients with hormone receptor-negative metastatic breast cancer) or aromatase inhibitor (for patients with hormone sensitive metastatic breast cancer). It slows or stops cancer cells from growing or may kill them.

USES OF CADILAP 250MG

• HER2-positive metastatic breast cancer

HOW CADILAP 250MG WORKS

CADILAP 250MG is an inhibitor of intracellular tyrosine kinase domains of both HER2 and epidermal growth factor receptor (EGFR). It passes through the cell membrane and binds to HER2 and EGFR, found inside the cell. Inhibition of HER2 and EGFR receptors by lapatinib, inhibits the HER2-derived tumor cell growth and division, which in turn reduces tumor cell proliferation.
