Lorbrexen 100 mg (Lorlatinib): Uses, Benefits, and Important Information
Lorbrexen 100 mg, also known by its generic name Lorlatinib, is a targeted cancer medicine. It is mainly used to treat patients with a special type of lung cancer called non-small cell lung cancer (NSCLC). This type of lung cancer often has a change in the ALK (anaplastic lymphoma kinase) gene, which helps cancer cells grow and spread. Lorbrexen works by blocking this abnormal gene and stopping the cancer cells from growing.
In this article, we will explain what Lorbrexen 100 mg is, how it works, its benefits, side effects, and precautions you need to know.
What is Lorbrexen 100 mg (Lorlatinib)?
Lorbrexen 100 mg is an oral medication that belongs to a group of drugs called kinase inhibitors. It is specially designed for patients whose lung cancer has ALK-positive mutations. Doctors often prescribe it when other treatments have stopped working or if the cancer has spread to other parts of the body, including the brain.
How Does Lorbrexen Work?
Cancer cells with ALK-positive mutations depend on this abnormal protein to survive and grow. Lorbrexen blocks the action of this protein, making it harder for cancer cells to spread. Unlike some older medicines, Lorbrexen can also cross the blood-brain barrier. This means it can help treat or prevent cancer that spreads to the brain, which is common in ALK-positive lung cancer.
Benefits of Lorbrexen 100 mg
Effective against advanced cancer: Works for patients with ALK-positive lung cancer that has spread.
Brain protection: Helps control or reduce tumors in the brain.
Second-line treatment: Useful when other ALK inhibitors (like crizotinib or ceritinib) are no longer effective.
Improves survival rate: Patients often live longer and maintain better quality of life.
How to Take Lorbrexen 100 mg
Lorbrexen is usually taken once daily by mouth.
It can be taken with or without food.
Patients should swallow the tablet whole with water, not crush or chew it.
Always follow your doctor’s instructions carefully.
Possible Side Effects
Like all cancer medicines, Lorbrexen 100 mg may cause side effects. Some common ones include:
Weight gain
Swelling in hands or feet

Pregnant or breastfeeding women should avoid this medicine, as it may harm the baby.
Patients should have regular blood tests to check cholesterol, liver function, and overall health.
Avoid alcohol and grapefruit products, as they may interact with Lorbrexen.
Conclusion
Lorbrexen 100 mg (Lorlatinib) is a powerful treatment for ALK-positive non-small cell lung cancer. It gives hope to patients whose cancer has spread or stopped responding to other medicines. While it has side effects, careful monitoring and medical guidance can help manage them. If you or your loved one has been prescribed Lorbrexen, always take it as directed and stay in close contact with your healthcare team.
