Afatinib Dimaleate 20mg (Xovoltib)

Afatinib Dimaleate 20mg (Xovoltib)

Xovoltib 20mg contains Afatinib Dimaleate 20mg, an oral targeted anticancer medicine belonging to the tyrosine kinase inhibitor (TKI) class. Afatinib is an irreversible blocker of the ErbB family of receptors, including EGFR, HER2, and HER4, which are involved in signaling pathways that can promote cancer cell growth and survival.

Afatinib is primarily used for selected patients with metastatic non small cell lung cancer (NSCLC) whose tumors have specific activating EGFR mutations. It is also indicated for certain metastatic squamous cell lung cancers that have progressed after platinum based chemotherapy. Treatment selection depends on tumor characteristics, previous treatment, and the patient's overall condition.

Xovoltib 20mg is generally used when a lower afatinib dose is appropriate, such as following dose adjustment because of treatment related adverse effects. The starting dose for EGFR mutation positive NSCLC is commonly higher, so the 20mg strength should be taken only according to the oncologist's instructions.

What is Afatinib Dimaleate 20mg (Xovoltib) Used For?

Xovoltib is used in selected patients with advanced or metastatic lung cancer.

Common Uses

• Metastatic NSCLC with specific EGFR mutations
• NSCLC with EGFR exon 19 deletions
• NSCLC with EGFR exon 21 L858R substitutions
• NSCLC with other non resistant EGFR mutations that may respond to afatinib
• Metastatic squamous cell carcinoma of the lung after progression following platinum based chemotherapy
• Dose adjusted treatment when clinically appropriate

Molecular testing of the tumor is important when determining whether afatinib is appropriate for EGFR mutation positive NSCLC.

How Afatinib 20mg Works

Afatinib targets signaling pathways involved in cancer cell growth.

Mechanism of Action

• Irreversibly blocks EGFR and other ErbB family receptors.
• Inhibits signaling pathways that promote tumor cell growth.
• Reduces proliferation of susceptible cancer cells.
• Interferes with cancer cell survival signaling.
• Helps slow tumor progression in cancers driven by susceptible ErbB signaling abnormalities.

How to Use Afatinib 20mg

Proper administration helps maintain consistent absorption.

Directions for Use

• Take exactly as prescribed by your oncologist.
• Take the tablet on an empty stomach, at least 1 hour before or 2 hours after a meal.

• Take it at approximately the same time each day.
• Do not change the dose or stop treatment without medical advice.
• If a dose is missed, take it when remembered unless the next scheduled dose is due within 12 hours.

The usual starting dose for EGFR mutation positive metastatic NSCLC is 40mg once daily, while 20mg may be used after dose reduction when clinically appropriate.
