Treat Cancer with Osimertinib

About – Osimertinib

The medicine Osimertinib is used to treat non-small cell lung cancer that has been detected as having an abnormality in the gene “EGFR”. Usually, Osimertinib is given to patients with cancer that has spread to other parts of the body (metastatic) or to patients who have cancer that has returned after surgery as targeted therapy.

This drug, marketed under the trade name Tagrisso by pharmaceutical API manufacturers,  is an inhibitor of the third generation’s epidermal growth factor receptor tyrosine kinase.

If you have been diagnosed with EGFR abnormality, you will be tested by your doctor and will be prescribed this medication.

How is Osimertinib useful in treating cancer?

As an antitumor medication, Osimertinib is used to treat certain types of non-small-cell lung cancer (NSCLC) after it is removed by surgery. This medication is prescribed for adults with either locally advanced or metastatic NSCLC. As part of the treatment option and protocol, it may also be used as the second or even the first treatment for a certain type of NSCLC that has spread to other body parts. 

Osimertinib is also used by adults who have been unable to get treatment for cancer with other similar radiation therapy medications to treat certain types of cancer that have spread to other parts of the body. It blocks the abnormal protein, which is responsible for causing cancer cells to multiply by blocking its action on them. Cancer cells appear to stop or slow their spread when this action is undertaken, and tumours may shrink as a result.

The EGFR activating mutations in tumours that the EGFR-targeted drugs also target Osimertinib targets (exon 19 deletions and exon 21 L858R). The therapeutic regimen was also designed to kill cancer cells with the T790M mutation of the EGFR, which has been shown to cause resistance to earlier-generation EGFR-targeted medications.
