Targeted drug erlotinib hydrochloride (Erlotinib)

Erlotinib Hydrochloride is a targeted therapy drug commonly used to treat EGFR (epidermal growth factor receptor) mutation-positive non-small cell lung cancer (NSCLC) patients. It belongs to the tyrosine kinase inhibitor (TKI) class of drugs. It interferes with the proliferation and growth of tumor cells by interfering with the activity of EGFR, providing a new direction for tumor treatment.

The targeting properties of this drug make it different from traditional chemotherapy drugs. It can more accurately target abnormal signaling pathways in tumor cells. EGFR is a membrane receptor protein that regulates cell growth, differentiation and survival through signal transduction. In some cancers, EGFR is overactivated, causing tumor cells to proliferate uncontrollably. Erlotinib hydrochloride can slow down the growth and spread of tumor cells by blocking the activation of EGFR.

Erlotinib hydrochloride generally has fewer toxic side effects than traditional chemotherapy. This means patients are likely to experience less discomfort while undergoing treatment and be able to maintain a relatively good quality of life. However, some adverse reactions may still occur, such as skin reactions, nausea, vomiting, diarrhea, etc. Prompt medical supervision and an individualized treatment plan are critical to minimizing these side effects.

The application of erlotinib hydrochloride usually needs to be customized according to the patient's genetic mutation to ensure the best effect of treatment. Doctors will use molecular testing to determine whether the patient's tumor has an EGFR mutation and then choose whether to add erlotinib hydrochloride to the treatment plan.
