Dacomitinib

Introduction

Dacomitinib is a prescription medicine used in the treatment of certain types of lung cancer, specifically non-small cell lung cancer (NSCLC). It belongs to a class of targeted therapies known as tyrosine kinase inhibitors (TKIs). Dacomitinib is usually prescribed when cancer has spread or is inoperable, and it targets specific mutations in the epidermal growth factor receptor (EGFR). By interfering with the cancer cells' growth signals, it helps to slow down or stop tumor progression. Always take this medication under the guidance of a qualified oncologist.

Uses of Dacomitinib

• Treatment of non-small cell lung cancer (NSCLC)
• Used when NSCLC has specific EGFR gene mutations
• Prescribed for advanced or metastatic cases

How Dacomitinib Works

Dacomitinib blocks the activity of EGFR (epidermal growth factor receptor), a protein found on the surface of some cancer cells. By inhibiting EGFR, it stops cancer cells from growing and multiplying. This targeted approach makes it more effective for tumors with specific genetic mutations.

Benefits of Dacomitinib

• Targeted therapy with high specificity
• Improves survival rate in EGFR-positive NSCLC patients
• Slows tumor growth and progression
• Oral dosage for convenient at-home use

Dacomitinib should be taken orally once a day, with or without food. Swallow the tablet whole with water and do not crush or chew it. The dosage is determined by your doctor based on your condition and tolerance. If you miss a dose, take it as soon as you remember unless it's close to your next dose—do not double the dose.
