MECHANISM OF ACTION:
Osimeritinib is similar in action when compared to other tyrosine kinase inhibitor drugs.Osimeritinib is named tyrosine kinase inhibitor of epidermal development factor receptor which is available on the surface of tumor cells
Osimeritinib is non-reversibly converge with mutant type of EGFR at 9 folds than wild sort
