1. What is Erlotinib Krka and what is it used for

Erlotinib Krka contains the active substance erlotinib. Erlotinib Krka is a medicine used to treat cancer. The mechanism of action of the medicine involves inhibiting the activity of a protein called epidermal growth factor receptor (EGFR). This protein is involved in the process of growth and spread of cancer cells. Erlotinib Krka is indicated for use in adult patients. This medicine may be prescribed to patients with advanced non-small cell lung cancer. It may be used as a first-line treatment or when the disease has not progressed significantly after first-line chemotherapy, provided that the tumor cells have specific EGFR mutations. Erlotinib Krka may also be used when previous chemotherapy has not stopped the progression of the disease. This medicine may also be prescribed in combination with another medicine called gemcitabine to patients with pancreatic cancer with metastases.
