Lapatinib i Description
Lapatinib is an inhibitor of EGFR/HER2 (ErbB2) that is currently in clinical trials as a co-administered treatment with other chemotherapeutics. Lapatinib exhibits anticancer chemotherapeutic benefit, inducing apoptosis in breast cancer cells. This compound also downregulates expression of thymidylate synthase in vitro.
Lapatinib is a tyrosine kinase receptor inhibitor used in the therapy of advanced breast cancer and other solid tumors. Lapatinib therapy is associated with transient elevations in serum aminotransferase levels and rare instances of clinically apparent acute liver injury.
Lapatinib is an anti-cancer drug developed by GlaxoSmithKline (GSK) as a treatment for solid tumours such as breast and lung cancer. It was approved by the FDA on March 13, 2007, for use in patients with advanced metastatic breast cancer in conjunction with the chemotherapy drug Capecitabine. Lapatinib is human epidermal growth factor receptor type 2 (HER2/ERBB2) and epidermal growth factor receptor (HER1/EGFR/ERBB1) tyrosine kinases inhibitor. It binds to the intracellular phosphorylation domain to prevent receptor autophosphorylation upon ligand binding.
