The mechanism of lapatinib and its application in breast cancer

Abstract

This paper aims to study the synthetic route, mechanism of action and application of lapatinib in breast cancer. As a common malignant tumor, breast cancer poses a serious threat to the life and health of patients. As an effective targeted drug, lapatinib is significant in treating breast cancer. Its pharmacological effects can block the growth and metastasis of tumor cells by inhibiting specific signaling pathways and affect cancer cells metabolism and drug efficacy. Its molecular mechanism is mainly through targeting the epidermal growth factor receptor (EGFR) to inhibit the proliferation and survival of tumor cells. Studies on lapatinibs drug metabolism and pharmacodynamics also described its metabolism and therapeutic effect in vivo. Secondly, the pathophysiology of breast cancer was summarized, including the pathogenesis, clinical manifestations, and molecular biological characteristics of breast cancer. The therapeutic effect, application, efficacy evaluation, and adverse reaction management of lapatinib were analyzed for the application of lapatinib in the treatment of breast cancer. Moreover, the existing lapatinib synthetic routes were described. Lapatinib has a substantial treatment influence and may effectively decrease harmful reactions when used to treat breast cancer. Nevertheless, additional study is required to ascertain its optimal application and possible mechanism of action in breast cancer treatment.
