Erlotinib Hydrochloride

What Erlotinib Hydrochloride Means in Everyday Medical Language

Erlotinib hydrochloride is a cancer medicine often called by its brand name Tarceva or by research names like CP-358,774 and OSI-774. It belongs to a group of drugs known as tyrosine kinase inhibitors. These drugs work by blocking a protein called the epidermal growth factor receptor (EGFR), which some cancer cells use to grow and multiply. By blocking EGFR, erlotinib may help slow or stop the growth of certain cancers.

Why Erlotinib Hydrochloride Can Matter in Cancer Care

This drug is important because it offers a targeted treatment option for people with non-small cell lung cancer (NSCLC) that has spread and carries specific mutations in the EGFR gene. It is also used together with another chemotherapy drug, gemcitabine, to treat pancreatic cancer that cannot be removed by surgery or has spread. Targeted therapies like erlotinib may work when other treatments do not and often have different side effects compared to traditional chemotherapy.
