For those diagnosed with advanced NSCLC with an EGFR mutation, Tagrisso (also known as Osimertinib) is considered the gold standard targeted treatment drug globally.
Being the third generation of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR TKIs), it specifically acts on common EGFR mutations such as exon 19 deletion and exon 21 L858R, and T790M resistance mutation.
The main obstacle for the patient and his/her family is the cost. For example, the innovator brand of Tagrisso manufactured by AstraZeneca costs around ₹1,00,000 to ₹1,50,000 per strip (approximately $1,200 to $1,800+ USD).
Fortunately, international healthcare hubs and Indian oncology suppliers provide access to affordable generic Osimertinib 80 Mg substitutes.
These generic alternatives contain the identical active pharmaceutical ingredient at a fraction of the original price.
What is Osimertinib 80 mg and Why is 80 mg the Standard Dose?
Osimertinib acts on the mutated EGFR tyrosine kinase enzymes present in cancer cells to hinder tumor replication and promote apoptosis while accessing the CNS to manage brain metastases.
- Universal Maintenance Dose: The universally accepted dose of osimertinib for treating advanced NSCLC and post-surgical management is a single oral dose of 80 mg per day.
- 40 mg Dose: The 40 mg dose of osimertinib is used only when the patient is unable to tolerate the standard dosage due to adverse events (e.g., diarrhea, skin rash, QT prolongation).
