How to use osimertinib in Bangladesh? What are the side effects?

Osimertinib (Osimertinib), developed and produced by AstraZeneca in the UK, is an epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) and a third-generation targeted anti-cancer drug. It is mainly used to treat non-small cell lung cancer (NSCLC) carrying EGFR mutation genes. By specifically inhibiting the activity of the EGFR receptor, it blocks the growth signals of tumor cells, thereby prolonging the patient's survival and improving the quality of life. In recent years, with the development of the generic drug market, multiple versions of osimertinib have appeared on the Bangladeshi market, including Yaopin International version, Incepta Pharmaceutical Factory version, Everest Pharmaceutical version and Beacon version. These generic drugs are more affordable than the original drugs, making this important treatment affordable for more patients.

For locally advanced, unresectable (stage III) EGFR mutation-positive non-small cell lung cancer, an 80 mg tablet is administered orally once daily after platinum-based chemoradiotherapy until disease progression or unacceptable toxicity occurs. For first-line treatment of EGFR mutation-positive metastatic non-small cell lung cancer, 80 mg once daily until disease progression or unacceptable toxicity.
