Product Introduction:
Spexib 150mg is an oral targeted therapy for patients with advanced or metastatic ALK-positive non-small cell lung cancer (NSCLC). It is typically prescribed when other ALK inhibitors (like Crizotinib) are not effective.
Uses of Spexib 150mg
Spexib 150mg is mainly used for:
-
Non-Small Cell Lung Cancer (NSCLC) – Specifically for ALK-positive advanced or metastatic lung cancer.
-
Patients resistant to Crizotinib (another ALK inhibitor).
-
Lung Cancer with Brain Metastases – Can cross the blood-brain barrier.
-
Maintenance Therapy – Helps slow cancer progression.
-
Improves Symptoms – Helps reduce cough, breathlessness, and weight loss in NSCLC patients.
How Spexib 150mg Works (Mechanism of Action):
-
Ceritinib is an ALK inhibitor that targets and blocks the anaplastic lymphoma kinase (ALK) protein, which is responsible for cancer cell growth.
-
By blocking ALK, Spexib stops the spread and growth of cancer cells.
-
It also works in the brain, helping patients with brain metastases from lung cancer.
✅ Spexib is effective in patients who develop resistance to Crizotinib.
