Lapatinib manufacturers

Lapatinib is a synthetic, orally-active quinazoline with potential antineoplastic properties. Lapatinib reversibly blocks phosphorylation of the epidermal growth factor receptor (EGFR), ErbB2, and the Erk-1 and-2 and AKT kinases; it also inhibits cyclin D protein levels in human tumor cell lines and xenografts. EGFR and ErbB2 have been implicated in the growth of various tumor types.

Lapatinib is a small molecule inhibitor of several tyrosine kinase receptors involved in tumor cell growth that is 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.
